Typically, May marks the transition from Costa Rica’s dry season to its “green season.” This period signifies a shift in precipitation patterns, with increased rainfall throughout the country. While mornings often remain sunny, afternoons and evenings are more likely to experience showers or thunderstorms. Temperatures remain warm, generally in the high 70s to mid-80s Fahrenheit (mid-20s to low 30s Celsius), but humidity levels also rise.
Understanding the climatological characteristics of this transitional month is crucial for travelers. The increasing rainfall invigorates the lush landscapes, making for vibrant scenery and creating optimal conditions for flourishing flora and fauna. This period can offer lower prices on accommodations and fewer crowds compared to the peak dry season. Planning activities with the awareness of potential afternoon rain allows visitors to fully enjoy the natural beauty and diverse experiences Costa Rica offers. Historically, this shift in weather patterns has played a significant role in the agricultural cycles and cultural practices of the region.
