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.
