Papua New Guinea
Narrative updated. “Highland frost, failed rains and a rice shock: the 2026-27 El Niño is already rewriting PNG's food map”
Papua New Guinea is again in the crosshairs of a powerful El Niño, with The Guardian reporting that frost and drought are already raising the risk of food shortages across the highlands. Measured conditions for July–October 2026 show rainfall 10% below the 1991–2020 normal and temperatures 0.4°C above average, a dry-season signal that matters less for its own total than for what it says about the coming wet season. IFPRI's work on rainfall, gender and child nutrition warns that when those rains fail, it is women and young children who absorb the hunger first, while PreventionWeb and Yale Climate Connections flag a brewing 2026-27 event that could disrupt Asia-Pacific rice supply and, by extension, PNG's imported staple.
163.1 mm vs 182.1 mm normal
Reanalysis shows rainfall 10% below the 1991–2020 normal for July–October 2026, a period that is climatologically the dry season in Papua New Guinea, so the more telling signal is the outlook for the coming wet-season rains, which articles expect to arrive late and weak.
News source22.96°C mean vs 22.52°C normal
Mean temperatures ran 0.4°C above normal during the same window, consistent with the warming background that amplifies highland frost risk when clear, dry El Niño nights set in.
News sourceEl Niño typically makes Papua New Guinea drier. Observed rainfall is running -10% — too close to normal to call yet.
NASA POWER (MERRA-2) reanalysis, 9 Jul 2026 – 6 Oct 2026, sampled at the country centroid (-6.0°, 147.0°). Normals are 1991–2020. How this is computed

Observed monthly rainfall against the 1991–2020 climatology
Sector by sector
Highland sweet potato, taro and coffee face frost damage and a shortened growing window, while rain-fed rice planting is expected to slip by about a month.
Dry-season creek and spring levels are likely to fall further in the highlands and Sepik–Fly catchments, straining village water supplies and small-town reticulation.
Child nutrition is expected to deteriorate where the wet season is late, with diarrhoeal and waterborne disease risk rising as communities fall back on unprotected water sources.
Reduced river flow threatens the Ramu and Warangoi hydro schemes, raising the likelihood of load shedding and heavier reliance on costly diesel generation.
Coastal and riverine catches may dip as warmer surface waters shift tuna and reef-fish distribution, while low river flows hamper inland fishing and barramundi breeding.

2023-24
A strong El Niño contributed to delayed wet-season onset and localized food and water stress, foreshadowing the more severe 2026-27 event now brewing.
unsourced background2015-16
One of the strongest El Niño events on record caused drought and frost across the highlands, forcing school closures and emergency relief as gardens failed and water sources dried up.
unsourced background1997-98
A severe El Niño brought prolonged drought and highland frost that destroyed staple gardens and triggered a national food crisis, with emergency food distribution reaching remote communities.
