May weather forecast
São Tomé and Príncipe

In São Tomé and Príncipe, May signals the conclusion of the rainy season. Rainfall levels start to decrease compared to April, though they remain significant, often between 130mm (5.12") and 150mm (5.91"). This continues to support the vibrant green landscapes that characterize the islands.

Despite the change in precipitation, the temperature in May remains stable and consistent with the rest of the year, typically ranging from 22°C (71.6°F) to 30°C (86°F). Coastal cities such as São Tomé and Santo Antonio follow this general trend. However, in higher altitude regions, for instance, the Obo National Park, temperatures can be a bit cooler due to the influence of altitude.

May represents a transitional period in the country's climate, as the heavy rains of the wet season start to recede, giving way to the drier months ahead. The transition into June marks the onset of the dry season, with rainfall levels reducing significantly. Nonetheless, the temperature continues to remain consistent, reinforcing the year-round tropical climate that São Tomé and Príncipe is known for. Despite the decrease in rainfall, the precipitation in May continues to nourish the islands' flora and fauna, including the country's important cocoa plantations.
