With the arrival of April, Brazil begins to experience the cooler temperatures of the autumn season. The northeastern regions and the Amazon Basin, while still warm, notice a further reduction in temperatures compared to the preceding months. Here, temperatures continue to remain above 30°C (86°F), but the scorching heat of the summer months becomes a memory.

The ocean temperatures along the coasts of north-central Brazil begin to gradually cool from their March peaks, but remain suitable for aquatic activities. The change in season often brings a refreshing ambiance to Brazil's coastline.

In southern Brazil, the temperate climate transitions further towards the cooler side. The highlands and mountains notice a more significant decrease in temperatures, heralding the approach of the cooler months of the year, especially when compared to the upcoming month of May.

April also marks a decrease in rainfall across Brazil. The Amazon region continues to receive substantial rainfall, although less intense than the wet summer months. The northeastern regions maintain their arid conditions, but the overall climate in Brazil becomes less humid, a trend that continues into the subsequent months.
