When Will the 2026 El Niño Actually Hit Crop Supply? Mostly in 2027

Based on the Helios AI El Niño Tracker, July 2026 edition. Download the report for free below.

The market has already voted. Cocoa futures surged to multi-month highs in July on El Niño fears, robusta is back in the headlines, and every desk is asking the same question: how bad does this get, and when?

The second half of that question is the one most analyses skip. Helios AI monitors 34 crop-and-country combinations for the El Niño Tracker, and 24 of them already sit at Warning. But 16 of the 34 reach their highest drought risk in 2027, not 2026. The reason is calendar, not chance: the 2026 harvest is largely locked in before the event peaks, while the 2027 crop is grown straight through the aftermath.

If your coverage, contracts, or budget stop at the 2026 crop, you are looking at the smaller half of this event.

Where does the El Niño stand right now?

The Oceanic Niño Index crossed the +0.5°C El Niño threshold in spring 2026 and reached +0.98°C by the April to June reading, a rapidly developing event still climbing toward its winter peak. NOAA puts the probability of El Niño conditions through the December to February window at 97 to 98 percent, with a 63 percent chance of a very strong event.

That would place this El Niño in the same band as 2015-16 and 2023-24, the two reference events the market remembers. And 2023-24 is exactly why buyers are nervous: that episode helped push cocoa above $10,000 per tonne and reset how the market prices climate risk in soft commodities.

Why does most of the risk land in 2027, not 2026?

The event is projected to peak between November 2026 and January 2027. That peak date is the pivot. Crops whose yield-setting window closes before it are largely insulated this year. Crops whose window opens after it carry the risk into next year.

Tree crops show the delay most clearly. Coffee flowering in September to November sets the following year's crop. Palm bunch development runs five to six months behind a drought hit. West African cocoa pod-set in August to October shapes the main crop harvested into early 2027, and the 2027 pod-set happens in the El Niño's aftermath.

A few numbers from the Tracker's exposure table make the lag concrete. These are Helios AI drought scores, the share of production sitting in drought-flagged areas during the yield-setting stretch, comparing the second half of 2026 with the second half of 2027:

• Indonesian coffee: 8.9 to 39.6
• Vietnamese coffee: 16.1 to 36.9
• Indonesian palm: 2.9 to 28.1
• Chinese wheat: 9.1 to 28.9
• Cameroonian cocoa: 16.5 to 28.9
• Nigerian cocoa: 4.9 to 22.9

Same event, one year of lag. These are weather risk readings, not loss forecasts, and that is the point: most of the origins flagged for 2027 have not even planted the crop in question yet. The value of the signal is lead time.

What does the delayed hit mean for cocoa prices?

Cocoa is where the market is most sensitive, and where history is least helpful.

Across the 12 moderate-plus El Niño events since 1958, West African cocoa shows no consistent yield damage. Côte d'Ivoire averaged +2.1 percent in peak years, Ghana minus 0.6 percent. An analog-only view of this market would see nothing at all.

The forward-looking picture is different. Helios AI's weather forecast concentrates the 2027 cocoa drought load in Ghana, Nigeria, and Cameroon, with Côte d'Ivoire already hitting elevated stress now. Where history and the forecast disagree, the Tracker shows both, because the elevated signal is a weather forecast seeing something the past average cannot.

For a market that rallied roughly 46 percent in a month on El Niño headlines, the practical takeaway is that the fundamental test for West African supply arrives with the 2027 pod-set, after the event peaks, not before it.

Is robusta coffee the biggest delayed risk?

By the numbers, yes. Vietnam and Indonesia together supply roughly half of the world's robusta, and both post the highest 2027 drought scores in the entire Tracker: 36.9 for Vietnam and 39.6 for Indonesia. Ethiopia and Uganda are flagged for 2027 as well, meaning the delayed risk spans both robusta and arabica origins outside Brazil.

Brazil itself moves from 7.0 to 23.2 into 2027. Coffee supply had been recovering after the 2024-25 price spike, which is precisely why a synchronized 2027 stress event across origins would matter: it would interrupt a rebalancing the market is currently pricing as secure.

What about palm, sugar, and the grains?

Palm follows the same script as coffee. Indonesia, Malaysia, and Nigeria all carry their peak risk into 2027, with Indonesia jumping from 2.9 to 28.1.

Sugar splits by geography. Brazil is being hit now, with stress elevated this season. Thailand's risk lands in 2027, and Australia is building toward it.

The grains are quieter but not clean. US corn and soy both carry elevated 2027 readings during the July to August yield window, and Chinese wheat, corn, and soy all flag for 2027. Australian wheat tells the opposite story: historically it takes its hit while an El Niño builds and rebounds hard in the peak year, averaging +17.2 percent, a reminder that one event produces opposite outcomes depending on the crop calendar.

What should procurement teams do before November?

The actionable question is narrow: does your exposure sit before or after November 2026?

The make-or-break growing windows for the highest-risk origins arrive in sequence after the peak. Cameroonian cocoa in January 2027. Australian sugar in April. Then the run of July to August windows across Indonesian coffee and palm, Ugandan coffee, Nigerian palm, Thai sugar, and the US corn belt.

Almost none of those windows have opened yet. That is the reason to map exposure now rather than in hindsight, while there is still lead time to act on it.
