Autumn in Brazil officially begins on Friday, March 20, at 11:45 AM, and will last until June 21, with the Federal District experiencing a typical transition from the rainy season to the dry season. The National Institute of Meteorology (Inmet) reports that the region will see a gradual decrease in rainfall volumes. Weather forecasts indicate that temperatures may rise slightly, by up to 0.5 °C above average, compared to historical data.

April is expected to still bear features of the rainy season, with significant rainfall projected ranging from 100 to 140 millimeters for the month. Despite the initial precipitation, Inmet forecasts a noticeable decline in rain levels in the following months, with totals dropping to between 10 and 40 millimeters. This indicates that the month of April can still be characterized by wet conditions, while May and June are anticipated to exhibit the typical characteristics of a dry season in the Federal District.

The seasonal shift is significant as it marks the area's transition into drier conditions, impacting agriculture, water supply, and local ecosystems. Meteorologists emphasize monitoring these changes, as they will influence various sectors in the Central-West region of Brazil, necessitating adjustments in environmental management and planning during this transitional period.
