CNN Brasil reports that a forecast El Niño peak in November is raising concern over rain and drought contrasts across Brazil's key farm regions. Excess rain is hurting sugarcane harvesting and winter grains in the Centre-South, while Paraná's winter grain output is forecast at 2.84 million tonnes, down 28%, with wheat down 34% to 1.9 million tonnes.
Coffee areas benefit from moisture, while drought risk threatens Amazon nut production.
A sharp drop in Paraná wheat and barley supply raises Brazil's import needs and supports wheat prices, while El Niño-driven drought risk adds uncertainty to the 2027 corn and soy outlook.
