May weather forecast
Belize

May represents a transitional period in Belize as the country moves from the dry season into the wet season. During May, average temperatures fluctuate between a low of 24°C (75.2°F) at night and a high of 31°C (87.8°F) during the day. While the daylight duration remains around nine hours, humidity levels start to rise, causing the perceived temperatures to feel higher.

Coastal areas like Belize City and tourist-favorite San Pedro continue to enjoy a refreshing sea breeze, offering some respite from the increasing warmth and humidity. However, as the influence of the northern trade winds diminishes, the country starts to feel the effects of the approaching wet season.

Rainfall in May sees a substantial increase compared to April, with an average of 138mm (5.43") across the country. The start of May typically remains dry, but by the end of the month, rainfall significantly increases, especially in the southern and inland regions. Cities such as Dangriga and Punta Gorda receive the highest precipitation.

Compared to June, the following month, May is slightly cooler and less rainy. Despite the imminent onset of the wet season, the earlier part of May still offers suitable conditions for outdoor activities, including visits to Belize's archaeological sites and marine explorations along the Belize Barrier Reef. Towards the end of the month, as the rainfall increases, indoor activities and visits to museums and cultural centers become more appealing.
