NOAA’s Climate Prediction Center maintained its El Niño Advisory on November 9, reporting weekly sea-surface temperature departures of 4.7°C in Niño 1+2 and 2.3°C in Niño 3.4, with the August–October RONI at 2.0°C. The CPC said the event is strengthening and put the chance of a strong-to-very-strong El Niño through January–March 2027 above 83%.
A strong El Niño raises the risk of disruptive rainfall and temperature patterns in major crop-producing regions, potentially tightening supplies and supporting prices for exposed crops. The article gives a climate outlook, not a quantified crop impact, so price effects remain uncertain.
