Brazil’s INMET forecast puts the probability of very strong El Niño conditions by December at 95%, with the influence expected to continue into early 2027. The outlook points to lower rainfall and higher temperatures in parts of the North, Northeast, and Center-West, while the South could see above-average rain; agronomists recommend region-specific management, staggered planting, and soil cover.
The contrasting rainfall risks could affect crop establishment, fieldwork, and yields, with potential support for prices if dry or excessively wet conditions reduce output. No specific crop loss is established yet, so the price implications remain uncertain.
