NOAA Puts Historic El Niño Odds at 83% as Cocoa Mid-Crop Risk Builds for 2026/27

El Niño is still strengthening, and the odds of a historic event are rising. NOAA's Climate Prediction Center said in its October ENSO update that sea surface temperature anomalies have exceeded +4.0°C in parts of the eastern equatorial Pacific, with the Niño-3.4 index at +2.1°C, and put the probability of a historically strong event at 83% for October to December. For cocoa, the forecast splits the season in two: adequate rainfall for the West African main crop now building at ports, but a drier-than-normal January-to-March window that would strike the 2026/27 mid crop — the period when El Niño impacts typically bite hardest.

Niño-3.4 at +2.1°C; Historic Event Odds at 83% for October–December

The October ENSO Diagnostics Discussion from NOAA's Climate Prediction Center describes a coupled ocean-atmosphere system that strengthened further through September. Niño region indices reached +2.1°C in Niño-3.4, +3.0°C in Niño-3 and +3.9°C in Niño-1+2, with subsurface readings in excess of +10.0°C at depth in the eastern Pacific. CPC now assigns a 54% chance of a historic event — a three-month RONI value of +2.5°C or more, which would exceed every El Niño back to 1950 — for September–November, rising to 83% for October–December and holding at 70% for November–January. A strong-to-very-strong El Niño is rated likely, at greater than 83%, through January–March 2027. An earlier September assessment reported by Reuters had put the probability of a very strong event above 90%. The next scheduled CPC update lands on November 12.

The Regional Split: Safe Main Crop, Exposed Mid Crop

ECMWF's seasonal forecast, run September 1 and tracked by IBEX Commodities, maps the risk window precisely. For October–December the signal favors Ivory Coast and Ghana, with a 40–50% chance of above-normal rainfall — adequate for the main crop now arriving at ports. From January–March the signal reverses: below-normal rainfall becomes the most likely outcome, with the probability of landing in the driest quintile at 30–50% in Ivory Coast and 50–70% in Ghana, overlapping the Harmattan season and the period when the mid crop sets.

Ecuador faces the opposite problem. Coastal areas carry a 70–100% probability of rainfall in the wettest quintile for January–March, the heart of the wet season — a flood and harvest-disruption risk in the world's third-largest producer. The metric to watch is Niño-1+2 persistence rather than the peak: only two events in the past 45 years, 1997–98 and 1982–83, held above +3.0°C through the wet season, and both delivered rainfall more than double the neutral-year average. Indonesia, the largest Asian origin, carries the strongest dry signal of all for October–December, at a 70–100% probability of the driest quintile, though that eases considerably by the first quarter.

Markets Are Already Pricing the Risk

Trade estimates for the 2026/27 balance span an unusually wide range: Hedgepoint sees a surplus of 111,000 tons, Guan Chong has flagged a deficit of 300,000 to 400,000 tons, and general consensus sits at a deficit of 150,000 to 250,000 tons. The futures curve has repriced accordingly. ICE contracts for end-2026 delivery moved from roughly $3,400 per ton implied in early April to above $6,000 by early September, with 2027 positions holding above $6,200 for most of the year, according to PricePedia. Analyst surveys followed: the Consensus Economics August range for December 2027 ran $4,300 to $6,000 per ton, up from $2,800 to $3,800 in April.

The repricing has not been linear. New York December fell 8.8% in the week to September 22 as near-term supply weighed, then sold off again on October 1 to a low of $5,051 before buyers stepped in, closing at $5,448, up 2.06% on the day — a rebound traders read as a defense of the $5,300–$5,400 channel. Origin governments are reacting too: Indonesia raised its October cocoa export benchmark by 7.88% to $5,686 per ton, citing El Niño concerns over West African output.

What This Means for Buyers

• The risk is back-loaded. October–December rainfall favors the main crop; the threatened window is the January–March mid crop. Nearby price dips driven by arrival data do not remove 2027 risk.

• Review forward cover for first-half 2027 deliveries. The curve already prices 2027 above $6,200 per ton; waiting for a return to April levels means betting that the El Niño signal fails.

• Check Ecuador exposure. Flood risk through the wet season can disrupt the third-largest origin; confirm your supplier's origin mix and contingency stocks.

• Watch three markers. Weekly Ivorian arrivals through December, Niño-1+2 persistence into Ecuador's wet season, and CPC's November 12 update.

Our Position

Huanda Cocoa sources cocoa beans from West Africa, including Ivory Coast and Ghana, and processes them at three FSSC 22000 certified facilities in Cambodia, China and Indonesia, with COA documentation on every batch and exports to more than 62 countries. We are tracking ENSO indices and West African rainfall through our origin channels while contracting 2026/27 raw material. Buyers reviewing coverage for first-half 2027 deliveries can request current offers through our cocoa powder page; our earlier report on the dry spell is available at Ivory Coast cocoa arrivals flat as dry spell clouds the main crop.
