May weather forecast
Brazil

May brings a further cooling trend to Brazil as the country delves deeper into the autumn season. The northeastern regions and the Amazon Basin still manage to hold temperatures above 30°C (86°F), but the heat is noticeably milder compared to the summer months.

The coastal cities, such as Rio de Janeiro, experience a further reduction in temperatures, typically ranging from 22.8°C (73°F) to 27.2°C (81°F). The sea temperatures along the north-central coast start to cool more substantially but remain enjoyable for beachgoers and swimmers.

In southern Brazil, the shift to a cooler climate becomes more evident. The highlands and mountains display an even more significant decrease in temperatures compared to April. This cooling trend signals the approach of the winter season, which becomes more apparent in the upcoming month of June.

May is typically less rainy across Brazil. While the Amazon region still receives a substantial amount of rainfall, it is less intense than in the earlier months. In contrast, the northeastern regions continue their arid conditions, further reinforcing the transition from the humid summer to a drier autumn season. The reduced humidity and cooler temperatures make May a pleasant time to explore Brazil's vast landscapes and rich biodiversity.
