The autumn season in Brazil officially starts on March 20 at 11:45 AM, but it is expected to arrive without the expected cooling temperatures that many had hoped for. Recent weather models indicate that temperatures will remain above the historical averages during April, May, and June, with the heat of the summer lingering longer than usual. Specifically, April is predicted to feel the most like summer, characterized by warm weather, overcast skies in the afternoons, and sporadic rainfall, as no strong cold air masses are expected to change this situation.

In contrast, May is predicted to bring a more noticeable cooling, particularly as the days shorten and the sun's intensity decreases. By this time, nights across Brazil, especially in the Southern regions and higher altitudes of the Southeastern areas, will begin to feel fresher. This transition represents a significant change from the hotter conditions observed in April. According to Climatempo, a strong polar air mass is not anticipated to reach Brazil until the end of May, which marks the beginning of a more temperate phase in the season.

Overall, the forecast indicates an extended period of warm weather before the typical autumnal coolness sets in later. This extended warmth may have implications for agricultural practices and daily life in different regions, as people adjust their routines to the prolonged summer-like conditions.
