> Above-average temperatures and uneven rainfall have limited soil-moisture recovery in Brazil’s MATOPIBA region at the start of the 2026/27 soybean season. NOAA data showed a 2.47°C Niño 3.4 temperature anomaly in October, and the agency expected strong to very strong El Niño conditions through January–March 2027.
