# El Niño intensifies heat and keeps alert for start of soybean season in Matopiba

> Inmet warns that temperatures in Matopiba, covering parts of Maranhão, Tocantins, Piauí and Bahia, ran more than 2°C above historical maxima in September and October. Rainfall has been irregular at the start of the 2026/27 season, limiting soil moisture recovery in part of the region. The agency links the conditions to El Niño.

## Why it matters

Heat and uneven rain in Matopiba raise the risk of yield losses in one of Brazil's fastest-growing soybean areas. Any shortfall would tighten export supply and support soybean meal prices.
