Autumn 2026 in Brazil, beginning on March 20 at 11:45 AM, is forecasted to be characterized by above-average temperatures and inconsistent rainfall. Meteorologists predict that rainfall will last longer than usual, with a delay in the onset of intense cold. The season will continue until June 21, and typical transitions between summer and winter will exhibit gradual rain reductions, particularly in the interior of Brazil, alongside increased temperature variations over the months.

According to climate experts at Climatempo, autumn will generally be warmer than expected, with most regions experiencing above-average temperatures. The persistent warmth is likely to overshadow the cooler temperatures, with significant cold spells only predicted toward the end of May and into June, indicating a shift in seasonal weather patterns. As autumn progresses, meteorologists expect specific events of colder weather to emerge, particularly in the latter part of the season.

The implications of this weather forecast are significant for agriculture and water management in Brazil, as irregular rainfall and extended heat can impact crop yields and water supply. Farmers and stakeholders in sectors dependent on stable weather patterns may need to adjust their strategies to accommodate these forecasted changes, making it essential for them to stay informed on upcoming weather developments and adapt accordingly.
