What is the Weather Like in Costa Rica in May?
Early May still feels like the dry season, but as the month progresses, you’ll notice more rain, signaling the start of the green season. This period is characterized by occasional afternoon showers that offer some much-needed reprieve from the daytime heat. While the rain increases in most regions, places like Guanacaste can experience dry conditions with only brief showers.
Temperatures in May are a continuation of the warm weather typically associated with the dry season, typically ranging from the mid-70s to the mid-80s Fahrenheit (24-30°C).

The end of May marks the beginning of the rainy season in most of the country. While the first half of the month might still have some dry days, rainfall increases as the month progresses. Showers often occur in the afternoons or evenings, with mornings generally staying clear. The first rains of the season rejuvenate the landscape, painting the landscape with green.
