Kiribati
Score moved 8 → 7 (severe impact → high impact). “A record-strength El Niño is already rewriting Kiribati's dry season — and the real test comes with the November rains”
A rapidly intensifying, early-onset El Niño — described by WMO and Carbon Brief as a possible 'super' event — is now the dominant climate signal for Kiribati, with the Pacific island nation sitting squarely in the canonical wetter-than-normal corridor. Measured reanalysis for 9 July–6 October 2026 shows rainfall at +146% of the 1991–2020 normal and mean temperatures +0.3°C above average, even though this window falls in Kiribati's climatological dry season, so the anomaly is best read as a preview of an enhanced November–April wet season. ReliefWeb's Asia-Pacific snapshot and Islands Business reporting both flag the heightened risk of flooding, coastal inundation and waterborne disease as the peak El Niño impact period of November–March approaches.
800.8 mm vs 325.8 mm normal
Reanalysis shows rainfall at +146% of the 1991–2020 normal for 9 July–6 October 2026, a period that is climatologically Kiribati's dry season, so the meaningful signal is the outlook for the coming wet season rather than a percentage against a near-zero baseline.
News source28.41°C mean vs 28.07°C normal
Mean temperature for the same window ran +0.3°C above normal, a modest warming consistent with the strong El Niño state described in the articles.
News sourceEl Niño typically makes Kiribati wetter. Observed rainfall is running +146% — in line with the canonical response.

Sector by sector
Enhanced wet-season rains from November could waterlog pulaka and taro pits on low-lying islets, risking root rot even as freshwater lenses recharge.
Heavy rainfall is expected to replenish household and community rainwater tanks, but saltwater intrusion and contamination during flood events remain a serious concern.
Standing water and flooding raise the risk of diarrhoeal disease, typhoid and dengue outbreaks, with heat stress and nutrition stress compounding vulnerability in crowded South Tarawa settlements.
Increased cloud cover and rainfall may reduce solar output on outer islands, while storm damage to cables and fuel deliveries could interrupt diesel-based generation.
Warmer surface waters and altered currents are likely to shift tuna and coastal reef-fish distributions, disrupting both subsistence catch and government revenue from distant-water fishing licences.

2023-24
A strong El Niño delivered above-average rainfall to Kiribati's central and eastern islands, with coastal flooding and wave inundation reported in South Tarawa during the peak wet season.
unsourced background2015-16
A powerful El Niño contributed to prolonged drought across the Gilbert Islands, prompting a government-declared state of emergency in 2016 and large-scale water deliveries to outer islands.
unsourced background1997-98
One of the strongest El Niño events on record brought severe drought to western Kiribati and extreme rainfall to the central and eastern islands, forcing water rationing in South Tarawa and damaging subsistence crops.
