ENSO state — El Niño declared, forecast toward a very-strong winter peak

STAGE: BREAKING

NOAA CPC ENSO Diagnostic Discussion, 11 June 2026: ENSO Alert System Status = El Niño Advisory — "El Niño conditions are present and expected to strengthen into the Northern Hemisphere winter 2026-27." CPC's June 2026 official strength probabilities assign 98% to El Niño persisting and 63% to a very-strong (≥ +2.0°C) event at the November–January peak; an Advisory is CPC's declaration that the event is underway, not merely favored.

The symptoms

✅	CPC alert status at Advisory (event declared, not merely watched)present	"El Niño conditions are present and expected to strengthen into the Northern Hemisphere winter 2026-27." Advisory issued with the 11 June 2026 Diagnostic Discussion; reaffirmed in CPC's 29 June weekly update. This follows a weak 2025-26 La Niña that ended in early 2026. [source]	2026-06-11
✅	Oceanic Niño Index at the +0.5°C El Niño threshold, weekly values climbing past itpresent	ONI for Mar–May 2026 = +0.5°C, the first season at threshold (CPC flags recent ONI values as estimates). CPC's 29 June update lists weekly anomalies: Niño-3.4 +1.2°C, Niño-3 +1.5°C, Niño-1+2 +2.5°C — up from about +0.7°C in early June. Upper-ocean heat content is above average, consistent with continued intensification. [source]	2026-06-29
✅	Seasonal probabilities near-unanimous for persistence through winter 2026-27present	IRI/CPC Quick Look (22 June 2026): 98–100% El Niño probability every season through DJF 2026-27; no probability assigned to La Niña. CPC official strength probabilities (June 2026) for the Nov–Jan peak: 63% very strong (≥2.0°C), 25% strong, 10% moderate, 2% weak; 13 of 24 plume models reach ≥ +2.0°C in Sep–Nov. WMO's May 2026 update had already put JJA odds at 80%, rising above 90% by November. [source]	2026-06-22
◐	Attributable regional impacts materializing (Asian monsoon deficit)partial	India's June 2026 southwest monsoon closed roughly 40–43% below normal — reported as one of the driest Junes in 146 years — with IMD naming strengthening El Niño among the drivers alongside an unfavorable MJO and missing low-pressure systems. IMD cut its season outlook to 90% of the long-period average, with an 84% chance of below-normal-or-deficient rainfall; the South Asian Climate Outlook Forum also forecasts below-average monsoon rain. Marked partial: impacts are early-stage and multi-causal, and other canonical El Niño impact zones (Indonesia, Australia, southern Africa) show forecast risk, not yet documented damage.

—	Food-price coupling active in 2026absent	No documented global staple-price movement attributable to this event as of 1 July 2026. The historical channel is well documented: the 2015-16 very-strong El Niño cut southern African maize production by roughly 25% and doubled maize prices in South Africa and Malawi; the 2023-24 event brought the region's worst mid-season dry spell in over 100 years, with staple prices above the five-year average (FEWS NET alert, Nov 2023; OCHA, Sep 2024). The rice channel — monsoon deficits in India and Thailand, the two largest exporters — is the one now loaded by symptom 4. [source]	2026-07-01
✅	Forecast issued inside the high-skill window (past the spring predictability barrier)present	ENSO forecast skill drops sharply for forecasts made February–May and recovers for those made June–December (NOAA climate.gov, ENSO blog). The Advisory and the 63% very-strong figure are June issuances, anchored on observed +1.2°C conditions rather than springtime model extrapolation. Caveat retained: the strength forecast remains a forecast — the loudly predicted 2014 El Niño, forecast in March before the barrier, collapsed to weak. [source]	2026-06-22

The honest read

Base rate first: El Niño recurs every two to seven years, and most episodes are weak to moderate and pass without global crisis; only three events since 1980 (1982-83, 1997-98, 2015-16) reached the very-strong class CPC now gives 63% odds. Even 2015-16 produced severe regional hunger — not global famine — and every El Niño's ledger is mixed: drought risk in Asia-Pacific and southern Africa arrives alongside a typically quieter Atlantic hurricane season and wetter conditions in parts of the Americas. The 63% is a post-barrier June forecast, historically reliable but not infallible. The stage steps down if CPC withdraws the Advisory or winter probabilities collapse; within BREAKING, the escalation to watch is a realized ONI at or above +2.0°C plus FEWS NET/WFP food-security alerts in late 2026.

The watch

A future automated watcher polls: NOAA CPC ENSO Diagnostic Discussion + Alert System status — https://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_advisory/ensodisc.shtml — updated monthly on the second Thursday (next issuance 9 July 2026); the companion weekly evolution/status PDF at https://www.cpc.ncep.noaa.gov/products/analysis_monitoring/lanina/enso_evolution-status-fcsts-web.pdf refreshes every Monday.. Until then, the stage is reviewed by hand against the same sources — and says so.
