Climate Impact Company's September 15, 2025 alert says confidence is rising for an El Niño transition in 2026, with a marine heatwave in the Northeast Pacific a possible driver. It notes worsening drought across the Midwest to Northeast US and Ohio Valley, persistent Central/East Brazil drought, and easing drought in Central Europe.
Worsening US Midwest dryness and a Brazil drought that persists into planting season support corn and soybean prices, while the possible 2026 El Niño shifts South American risk later.
After 1,465 past bullish weather events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
After 1,079 past bullish weather events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
After 453 past bullish weather events, Soybean Meal moved a median +0.5% over 5 sessions (55% higher; middle half -1.6% to +2.7%), and +0.5% over 20.
