Autumn officially began in the Baixada Santista region of São Paulo at 11:45 AM on Friday, heralding a gradual transition in weather patterns. Unlike abrupt temperature drops, the region is expected to maintain warm conditions until April, with a forecast for milder temperatures thereafter. This seasonal change follows a notably unstable summer characterized by rainfall above historical averages.

During the onset of autumn, Bahia’s weather is anticipated to be less variable compared to the preceding months, although some rain is still possible, particularly in the initial days of the season. Meteorologist Franco Cassol from the Santos municipal government highlighted that the most significant temperature changes are expected to manifest in April, with May likely marking the establishment of more noticeable cooler temperatures.

This year's autumn arrives with greater stability than summer, even as the region continues to experience residual warmth. The transition into winter in June will further enhance the cooling trends, suggesting a significant shift in the local climate as the season progresses, which will impact both the environment and residents' daily lives.
