May weather forecast
Saint Lucia

May in Saint Lucia marks a notable shift in the weather as the island fully transitions into the rainy season. Temperatures remain high, ranging from 24°C (75.2°F) to 31°C (87.8°F), similar to April, but the humidity starts to increase noticeably due to the higher levels of rainfall.

May experiences a significant increase in precipitation compared to the preceding months, with the average rainfall jumping to approximately 170mm (6.69"). While the rains are more frequent than in the dry season, they often occur in short, intense bursts, leaving plenty of time for the sun to shine brightly.

All the major cities, including Castries, Soufrière, and Rodney Bay, experience similar climatic conditions. The coastal areas, while sharing the temperature range, continue to enjoy cooler evenings due to sea breezes, a refreshing end to the warm and humid days.

When May transitions into June, the changes in weather are less dramatic, with temperatures remaining consistent. However, rainfall continues to increase, marking a deeper progression into the rainy season. Despite the wetter weather, the island continues to showcase its tropical allure under the warm Caribbean sun.
