Pacific Dataviz Challenge 2026 · Papua New Guinea
Papua New Guinea’s worst droughts begin seven thousand kilometres away, in the temperature of the Pacific — months before the rain fails. In 2026 that ocean is warming fast. This is what El Niño does to PNG, and what to do about it.
Niño 3.4 anomaly +1.73 °C · July 2026
The problem. Papua New Guinea’s worst droughts are announced months early by a stretch of equatorial ocean seven thousand kilometres away — yet the warning is still easy to miss until gardens freeze and rivers stop. This piece answers that with the official Pacific climate record: it shows where the signal lives, what it does at every altitude in PNG, and a dated preparation calendar for the 2026–27 El Niño now underway.
In 1997, the rain over Papua New Guinea failed. Rivers dropped until the barges that supply whole districts stopped running. Gardens wilted from the coast to the high valleys, and on clear drought nights, highland sweet-potato gardens froze. It was the worst drought the country's modern record had measured. In 2015, it happened again.
Both times, the first sign was not in PNG’s sky. It was in the temperature of seawater seven thousand kilometres east — months before the rain failed.
It is happening a third time — the third time this catastrophe has come: 1997, 2015, and now. 1982 and 2023 were great El Niños in the ocean's record, but neither became this. In 2026 that ocean is warming faster than it did in any of the four — 1982, 1997, 2015, 2023 — at the same point in their onset years. PNG’s National Weather Service declared El Niño in June, after a first advisory on 1 May, and expects the drought to run into 2027.
What follows is the whole story, told through the official Pacific climate record and the reporting of the time: where the drought comes from, what it does to Papua New Guinea — and what can still be done about it.

the hard months ahead — and what to do in them is the last chapter
Chapter one · the map
Two places on this map run Papua New Guinea’s weather: the country itself, and a rectangle of open water on the equator, seven thousand kilometres east. What moves between them is the rain.
The tropical Pacific holds the warmest open ocean on Earth — the western warm pool, which sits just off Papua New Guinea. Warm water makes rising air, and rising air makes rain, so the country's weather rides on that pool. Every few years the pool moves. When it slides east along the equator — El Niño — the rain machine travels with it, and Papua New Guinea's sky runs dry. When the warmth piles back west — La Niña — the rain comes home, often violently. The shift is measured in a rectangle of open ocean called Niño 3.4 (5°N–5°S, 170°W–120°W), seven thousand kilometres east of Port Moresby: sea temperature there changes months before the rain does over land, which is why El Niño and La Niña are detected there first. The coastlines on the map are real (Natural Earth); the warm-pool motion is a drawing of the mechanism, not a measurement.
The tropical Pacific, equator centred · Papua New Guinea west, the Niño 3.4 detection box east
West, in dark ink: Papua New Guinea. East, past the date line: a dashed rectangle of open ocean called Niño 3.4. No land, no towns — just water. But that water decides PNG’s weather.
The sea next to PNG is the warmest open ocean on Earth. Warm water lifts the air above it, and rising air makes rain. That is where the country’s rain comes from.
Every few years the warm water slides east along the equator — and the rain goes with it, into the rectangle. Over Papua New Guinea the sky dries out. That is an El Niño: the start of PNG’s droughts.
Then the ocean swings back. Warm water piles up against PNG again, and the rain returns — often too much of it. Drought and flood are the two ends of the same swing.
The water in Niño 3.4 warms months before the rain fails over Papua New Guinea. So PNG’s droughts are never a surprise — they are announced, far out at sea, with time to prepare.
Chapter one · continued
Why does the warm water move? Go below the map: a cross-section of the equatorial Pacific, where the trade winds run a heat engine the width of an ocean — with two failure modes, El Niño and La Niña.
Below the map of chapter one sits the machinery. The trade winds blow along the equator from South America toward Indonesia, pushing sun-heated surface water ahead of them until it piles up in the west — a layer about 150 metres deep sitting on Papua New Guinea's doorstep, and the reason the air above it rises and rains nearly every afternoon. East, that same wind drags cooler water up from below: the boundary between the warm surface layer and the cold deep — the thermocline — reaches almost to the surface.
In an El Niño the trades fail, sometimes reversing for weeks. The piled-up warm water sloshes back down the equator; the thermocline see-saws — deep in the east, shallow in the west — and the rising, rain-making branch of the circulation moves to the middle of the basin. Over Papua New Guinea the same rearrangement means sinking air: the daily storms switch off, the sky hardens into haze, and the drought of chapter three begins. In a La Niña the trades strengthen past normal and every part of the normal year runs harder: more rain at home, drier east.
This drawing is a schematic of the mechanism — the depths are illustrative, the geography is real — but the engine itself is measured: the sloshing of the warm layer is exactly what the thermometer of chapter two reads.
The equatorial Pacific in cross-section · west left, east right · vertical scale exaggerated ≈ ×160
The trade winds blow steadily along the equator, pushing sun-warmed surface water west until it heaps up against Indonesia and Papua New Guinea — a warm layer 150 m thick. Air rises off it every afternoon: PNG’s ordinary rain.
Every few years the trade winds fail — sometimes reversing for weeks. The heaped-up warm water slides back east, and the rising, rain-making air moves with it to mid-ocean. Over PNG the air sinks instead: clear skies, no rain.
The other failure runs the engine harder: stronger winds, even more warm water against PNG, and heavier rain — floods — while the eastern Pacific turns bone dry. Same machine, opposite fault.
All of this reduces to one number: how warm the water in the Niño 3.4 rectangle is, compared with normal. That number has been recorded for over fifty years — and it is the next chapter.
Chapter two · the far ocean
The temperature of the Niño 3.4 rectangle, condensed to one number a year, is the Oceanic Niño Index. It is the simplest summary of PNG’s drought risk ever devised — here are nearly fifty years of it.
The Oceanic Niño Index tracks the sea-surface temperature of the Niño 3.4 region in the central equatorial Pacific — far east of Papua New Guinea. Most years it sits near zero. Every few years it tips: upward is El Niño, when the Pacific's warm pool drains east away from Papua New Guinea; downward is La Niña, when warmth piles back west. The great El Niños of the record are 1982, 1997, 2015 and 2023. The chart's newest season, 2025–26, is now complete in CPC's table too: a weak La Niña, peaking at −0.6. Naming what came after it, month by month, is what chapter nine is for. (The ONI is NOAA CPC data, the one series in this piece not from the SPC dataflow; see /prep.)
The Oceanic Niño Index — Niño 3.4 sea-surface temperature anomaly (°C), one bar per year, 1979–2025
One bar per year: how much warmer or cooler the Niño 3.4 region was than normal, since 1979.
Most years sit near zero. When the index tips up — El Niño — the Pacific’s warm water has moved east, away from Papua New Guinea, and PNG’s rain is at risk. Down is La Niña: the warmth, and the rain, pile back west.
1982. 1997. 2015. 2023. The four great El Niños of the modern record. Remember these years — the next chapter puts PNG’s rain underneath them.
The 2025–26 season has since been classified — a weak La Niña, peaking at −0.6, the last dip before the 2026 El Niño. Naming what came next, month by month, is what chapter nine is for.
Chapter three · the rain
Here is PNG’s own record: how much rain each year brought, above or below normal. Put it under the see‑saw, and the connection is hard to miss.
The Pacific Community's rainfall-anomaly record for Papua New Guinea (annual, 1979–2025) mirrors the far ocean: when the Oceanic Niño Index spikes upward — El Niño — the rain at home collapses. Eight of the ten driest years in the record are El Niño years; the other two, 1992 and 1993, sit in the trailing warmth of the long 1991–92 event.
Averaged across the record, El Niño years run −5.9 points against +3.8 points in all other years — a correlation of −0.64. Points, not millimetres: the dataflow publishes this series labelled “mm”, but at these magnitudes the values are a relative anomaly index around zero — Papua New Guinea’s rain runs to thousands of millimetres a year, so a true mm-scale national anomaly would read in hundreds. The relabelling changes no ranking and no correlation; the pattern is the point. And not every El Niño year is a drought year in every province — the monsoon and local geography modulate the rain — but every great El Niño on this record met a great shortfall.
The great El Niños of chapter two — 1982, 1997, 2015 — are the great droughts of this chart.

Put simply: when the far ocean warms, store water.

Chapter four · the island
Papua New Guinea runs from coral coastlines to 4,500‑metre peaks in the space of a hundred kilometres. Cut the island sideways and walk uphill: an El Niño year reaches every step, and it takes something different from each.
Papua New Guinea is not one landscape but a stack of them: island and coastal communities at sea level; the great lowland river plains of the Fly and the Sepik, where rivers are the roads; the highland valleys around 1,400–2,000 metres, where most of the country's kaukau (sweet potato) gardens grow; and the high slopes running up to Mt Wilhelm at 4,509 metres. An El Niño drought reaches all of it. On the coast and the smaller islands, rain tanks and shallow wells fail first. In the lowlands, the rivers themselves drop — in 1997 and again in 2015 the Fly fell so low that barges stopped, cutting the supply line for everything from food to fuel. In the Highlands the same cloudless weather works twice: by day the sun scorches gardens that have never needed watering, and at night, with no cloud blanket, the ground's heat radiates to space, and gardens above roughly 2,200 metres freeze. The cross-section drawn in this chapter is an illustration — the vertical scale is exaggerated — but the mechanism at each step is the documented record of 1997 and 2015.
Papua New Guinea, with the A–B section line marked from the south coast over Mt Wilhelm to the north
PNG is a mainland with a wall of mountains down its spine, two great rivers, and island provinces scattered across its own sea. Cut the country along the dashed line, A to B, and turn it sideways.
Coastal and island villages drink rain: tanks, shallow wells, small streams. In an El Niño year those fail first — and on an atoll there is no river to fall back on.
On the plains, the rivers are the roads. When the Fly drops, the barges stop — and food, fuel and medicine stop with them. It happened in 1997, and again in 2015.
Up in the valleys, where most of the nation’s kaukau (sweet potato) grows, gardens have never needed watering — the cloud does it. In an El Niño year the cloud is gone: weeks of hard sun, and the vines wilt.
The same cloudless sky that burns the gardens by day lets the ground’s heat escape by night. By dawn, gardens above the frost line are frozen — and dead. Drought here kills twice: by day and by night.
Dry tanks at the coast, stranded barges on the plains, scorched gardens in the valleys, frost on the peaks. One ocean signal, four different disasters — and in 1997 and 2015, PNG faced all of them in the same year.
Field note 01 · the rivers
In the lowlands the river is the road, the market and the water supply at once. Watch the dry season advance — and what fails, in the order it failed in 1997 and 2015. (An illustration of the mechanism, not a gauge record.)
Sandbars surface mid-channel. The deep-draft barges begin to wait for water that isn’t coming.
The barges stop. On the Fly this is the whole supply line — food, fuel, medicine — and in 1997 and 2015 it stayed shut for months.
Pump intakes and shallow wells now sit above the water. The river you can see is water you can’t reach.
Waterholes go bad, and fetching water becomes hours of every day — time that used to be gardening, school, work.
Field note 02 · the frost
Kaukau — sweet potato — is the staple food of the Highlands, and it grows to well past 2,200 metres. It survives up there because cloud works as a blanket. Take the cloud away and watch the same night twice. (An illustration of the mechanism; typical values, not station readings.)
That is why 1997 and 2015 hurt twice at altitude: the drought browned the gardens by day, and its cloudless nights froze what was left — killing the planting material for the next crop too. In the Highlands, an El Niño warning is also a frost warning.
Chapter five · the gardens
A shortfall on a rainfall chart is a shortfall in somebody’s garden. The national harvest record shows where the El Niño years landed — and misses where they landed hardest.
The Pacific Community's national crop-yield record for Papua New Guinea (1961–2024) climbs across the decades. Mark the four driest years — 1982, 1993, 1997 and 2015 — and only 1997 leaves a visible dent. That is itself a finding: most of the country's food grows in subsistence gardens a national yield-per-hectare figure barely sees, so a drought that empties village gardens can pass almost unnoticed in the national average. The deepest losses sit off this ledger. 1997 was the hardest year of the record: drought in the lowlands and frost in the Highlands in the same season — the double mechanism the island chapter and its field notes describe — brought one of the country's worst food emergencies in living memory.
National crop yield, kilograms per hectare, 1961–2024
The national harvest, measured as crop yield from 1961 to 2024. Mostly it climbs: better seed, better roads, better prices.
Now mark the four driest years: 1982, 1993, 1997, 2015. Only 1997 dents the line — 1982 and 1993 land mid-climb. A national average can absorb what a village cannot.
The dips look small. But most of PNG’s food grows in subsistence gardens that a national statistic barely counts. The worst losses are off this chart — in the villages the field notes just described.
1997 hit twice in one season: drought in the lowlands and frost above 2,200 metres. The gardens died — and so did the cuttings needed to replant them, which is why the hunger outlasted the drought.
Interlude · the aftermath
The end of an El Niño is its own disaster. The rain returns all at once, onto slopes the drought has stripped bare — and brings floods and landslides.
A drought kills the ground cover and bakes the soil hard. Hungry families move their gardens down into the riverbeds — the only damp land left. Then the ocean swings back. When the 2015–16 El Niño broke, the Wahgi valley in Jiwaka Province went almost straight from drought into floods and landslides that hit around five thousand households — the same communities that had just spent a year hungry.
So an El Niño year is paid for twice: once in the drought, once when it ends. The prepared response is known too — plant the flood-safe ground first, keep drains and slopes clear through the dry, and treat the first big rain as a warning, not a celebration.

Chapter six · the long record
El Niño comes and goes — it always has. What is new sits underneath it: the sea around Papua New Guinea, measured one number a year since 1850.
The Pacific Community's record of Papua New Guinea's sea-surface-temperature anomaly runs annually from 1850 to 2025. For a century it wobbles near zero; from the late 20th century it climbs; 2025 — at +1.1 °C — is the warmest reading in all 176 years. The sea-level record is shorter (satellite era, 1993–2023) and rises about 0.2 m across it. And one pointed footnote: the local sea is not what dries the gardens — warm local years are actually slightly wetter (correlation +0.48), because Papua New Guinea's rain lives on its warm water. The drought signal is genuinely remote, which is what makes it readable months ahead.
Sea-surface temperature, departure from the long-term average (°C), 1850–2025
The sea around PNG itself — one temperature reading a year, starting in 1850. Watch the year counter.
For the first hundred years: wobble. Warm years, cool years, no trend.
Then the climb. 2025: +1.1 °C — the warmest sea in the entire 176-year record.
Not just warmer — higher. Sea level around PNG has risen about 0.2 m since the satellite record began in 1993, which is why king tides and storm surges reach further inland than they used to.
The local sea is not what dries the gardens — warm local years are actually wetter (correlation +0.48). PNG’s droughts really are made by the far ocean. And that is the good news: a signal made far away can be read months in advance.

+1.1 °C
the sea around Papua New Guinea last year — the warmest in 176 years of record.
Chapter seven · the ledger
The see‑saw of El Niño is natural. The warming underneath it is not — and almost none of it is made in PNG.
In the Pacific Community's record, Papua New Guinea's greenhouse-gas emissions run between 0.9 and 1.7 tonnes of CO₂-equivalent per person across 1970–2024, ending at 1.0 — flat for half a century. The world average is about 6.6 tonnes per person (EDGAR, 2023 — the one reference figure in this piece not from the SPC dataflow, documented in /prep). The warming that raises the sea and sharpens the droughts of the earlier chapters is overwhelmingly made elsewhere; the consequences are carried here.
Greenhouse-gas emissions per person per year · one dot = 100 kg of CO₂-equivalent
One dot for every 100 kg of greenhouse gas emitted per person, per year.
The world average: 6.6 tonnes per person. Sixty-six dots.
Papua New Guinea: 1 tonne. Ten dots — and in fifty years of record, never more than 1.7.
The warming that sharpens PNG’s droughts is overwhelmingly made elsewhere, and PNG cannot wait for the rest of the world to fix it. What the country can do is be ready — and readiness starts with watching the signal. That is the next chapter.
Chapter eight · the watchers
The last chart of the record isn’t a temperature. It’s attention — PNG’s meteorological monitoring network, one number a year, since 1951.
The Pacific Community's record of Papua New Guinea's meteorological monitoring network runs from 1951, when the country reported a single station, to 2026, when it reports six. Six is the SPC indicator's own count, not the whole national network: Papua New Guinea's full observing network — manual, automatic and aviation stations — has always been far larger, but few stations keep the continuous, climate-quality records this dataset runs on, and coverage stays sparse. It is the least dramatic series in the dataset and the most important: every chart in this piece exists because someone kept measuring. And because Papua New Guinea's droughts are made by a far ocean that tips months before the rain fails, watching is not bookkeeping — it is early warning. The ocean has already tipped: the warning is chapter nine, month by month. The one open line in this yearly record — the 2025–26 season — is now classified too: a weak La Niña, peaking at −0.6, the last dip before the ocean tipped.
Meteorological monitoring stations reported, 1951–2026
This one isn’t a temperature — it’s who is watching. In 1951, Papua New Guinea reported exactly one meteorological monitoring station.
Today it reports six — the long-record core of the network. Every chart in this piece exists because someone kept measuring.
PNG’s droughts are made by a far ocean that tips months before the rain fails. So watching is not bookkeeping — it is early warning: time to fill tanks, plant differently, move supplies.
On 1 May 2026, this network — with the ocean instruments behind it — issued the warning: El Niño, months before the expected peak. The next chapter is that warning, month by month.
July 2026
+1.73 °C
the far ocean at July — warmer than 1982, 1997, 2015 or 2023 stood at the same point. By late August the weekly reading was about +2.60 °C.
Chapter nine · now
Every chapter so far reads the past, one year at a time. This one runs month by month, because it is happening now: in the first half of 2026 the far ocean warmed faster than in any event on record, and by August the official outlook expected a very strong El Niño. The one chart here that looks ahead is labelled as an estimate — on the chart itself.
Ocean data through July 2026 · live coverage to 19 August 2026
Month by month, the last three years hold the whole see-saw: the 2023–24 El Niño peaking near +2 °C, a weak La Niña through 2024 and 2025, then a fast reversal in early 2026 — from −0.40 °C in January to +1.73 °C by July. Laid over the 4 great El Niños of the record, 2026 at July is warmer than 1982 (+0.34), 2023 (+0.97), 1997 (+1.21) and 2015 (+1.35) were at the same point: this event is developing faster than any of its precedents. The months ahead are not yet measured, so the chart continues the 2026 line along the four precedents, weighting each by how closely its January–July matched 2026's. That gives a peak around +1.85 °C in November 2026, inside a range of +1.40 to +2.21 — an estimate, labelled as such.
The estimate should be read as a floor, not a ceiling. The quoted weekly Niño 3.4 index for the week centred 19 Aug 2026 was about +2.60 °C — above anything the four precedents reached by that month, and above the whole range the estimate allowed for it. All 4 precedents were cooler than 2026 at July, which is why paths drawn from their own levels run low. Started from where 2026 actually is, the same 4 trajectoriesput August at +1.90 and peak near +2.56 °C. The official outlook agrees: as of mid-August 2026 an El Niño Advisory is in effect, the chance of a very strong event (≥ +2.0 °C) through the 2026–27 fall and winter is put above 90 % — with a 69 % chance the peak exceeds every El Niño since 1950.
On a calendar, that means the hard months — failing rain, falling rivers, frost-prone highland nights — run from now to about March 2027, which is also where Papua New Guinea's National Weather Service puts the end of the drought; on the faster reading they run to about May 2027. The swing back to heavy rain arrives around June 2027, and the first big rain on drought-bared slopes brings floods and landslides of its own.
Niño 3.4 anomaly (°C), month by month · observed to July 2026, plus one cited weekly reading
Month by month, the last three years: the 2023–24 El Niño, a weak La Niña through 2024–25 — then, in early 2026, a fast flip. January: −0.40 °C. April: +0.74. July: +1.73 and climbing. PNG’s National Weather Service issued its first El Niño advisory on 1 May 2026.
Lay 2026 over the 4 great El Niños, month for month. At July of their first year: 1982 +0.34., 2023 +0.97., 1997 +1.21 (the drought that emptied the rivers)., 2015 +1.35. 2026 stands at +1.73 — above all four: no event in this 57-year record has started this fast. The ringed marker, just past the line's end, is the quoted weekly reading for late August — about +2.60 °C, a different product from the monthly series: marked, never joined to the line.
Nobody has measured the rest of 2026, so the chart continues the red line along the only guide that exists: the 4 precedents. That path peaks near +1.85 °C around November, inside the precedents’ +1.40-to-+2.21 range. It is an estimate, drawn dashed — not an official forecast. The official outlook agrees: a very strong event (above +2.0 °C) in late 2026, holding into early 2027.
Treat that band as a floor, not a ceiling. The estimate for August was +1.19, inside a range up to +1.49 — and the quoted weekly reading, about +2.60 °C, sits above the whole band. Re-run the same four paths from 2026’s own level and they peak near +2.56 °C — the lighter dashed line. Plan for at least the precedents, and possibly more.
Now to about March 2027: the hard months — failing rain, falling rivers and dams, frost nights above 2,200 m. PNG’s weather service gives the same end date, and on the faster reading it runs to about May 2027. Around June 2027: the rain returns — and the first heavy rain on drought-bared slopes brings floods and landslides. The last chapter is what to do in each of these windows.

Interlude · 2026, on the record
The 1997 and 2015 documents above come from archives. These are being written now: the declaration, the directives, the frost reports and the first impacts of the 2026 event, as reported. Seven documents — and they follow the old pattern exactly.
The official drought early-warning system, mid-escalation — the same DEWS tiers chapter four maps, filling in for 2026.
The official confirmation, on the record: after a first advisory on 1 May 2026, the national service’s director confirmed in June that El Niño conditions are established — and named what they will do to the country.
The national directive: every province and district told to prepare before conditions worsen, with outlooks pointing to El Niño persisting through the second half of 2026.
The capital’s version of the drying river: the dam that waters and powers Port Moresby, drawn down under a rain that has not come.
The forecast horizon lengthens. The national service names the six Highlands provinces under warning and puts the end of the drought in the first quarter of 2027 — the same calendar chapter nine’s estimate arrives at from precedent alone.
The first impacts on the domestic record — and they follow the exposure map of 1997 and 2015 exactly.
The far-ocean signal chapter nine reads, updated. The 13 August discussion moved the official expectation again: not just a very strong event, but a real chance of one that exceeds every El Niño since 1950.
External links; summaries are our own reading of each document as of 19 August 2026. Compare with the 1997 and 2015 shelf above: the same provinces, the same altitudes, the same rivers. The difference this time — the warning came first.
What to do
Nobody can stop an El Niño, and nothing will cool the far ocean. But this one has been announced months in advance, and the record shows exactly what fails, in what order: water first, then the rivers, then the gardens, then the frost — and the floods at the end. Here is what to do with that warning, and when.
01
The ocean signal is public and runs months ahead of PNG’s rain. Follow the PNG National Weather Service and NARI’s drought updates — and when a drought alert is named for your province, treat it as a start date for action, not a headline.
02
Fill tanks and containers while rivers and rain still run; fix gutters and protect wells. Communities should map their water sources and agree on rationing before the dry deepens — after the taps fail, every option costs more.
03
Shift gardens toward drought-hardy staples — cassava, taro, banana, resilient kaukau varieties — and protect planting material. Above 2,200 m, prepare for frost nights: cover and mulch what you can, and hold back cuttings to replant after.
04
The drought ends in water. Through the dry months: clear drains and waterways, keep new gardens out of riverbeds, and plan where people and supplies go if slopes slip. Treat the first heavy rain around June 2027 as a warning, not a celebration.
The same list exists at national scale: fund the weather service and the drought early-warning system, pre-position food, fuel and medicine for the river towns, and release drought funds on the ocean’s calendar — before the emergency, not after it.

The ocean has already announced this El Niño. 1997 and 2015 wrote the playbook, in hunger and frost and flood. This time, Papua New Guinea can use it.
Every official series used in this piece, drawn small and together: Papua New Guinea's sea-surface and land-surface temperature anomalies, its rainfall anomaly, sea level, crop yield and greenhouse-gas emissions per person — each the annual national record from the Pacific Community, on the Pacific Data Hub. The warming lines climb, the rainfall spikes down in the El Niño years, the sea rises, and the emissions that drive it all stay near the floor.
