May marks the transition from Costa Rica’s dry season to its green season. Characteristically, the Pacific coast experiences sunshine in the mornings followed by afternoon showers, while the Caribbean coast typically receives rain throughout the day. Temperatures remain warm, averaging between the mid-70s and mid-80s Fahrenheit (mid-20s to high 20s Celsius). Humidity levels are notably higher on the Caribbean side.
Understanding these typical climatic conditions is crucial for travelers planning trips during this period. Packing appropriately for both sunshine and rain is essential. The shift in weather patterns can impact outdoor activities, and being prepared allows visitors to fully enjoy the diverse ecosystems and activities Costa Rica offers. Historically, May has provided a shoulder season advantage, with fewer crowds and potentially lower prices compared to the peak dry season. This transitional month offers a unique experience of the country’s natural beauty, as the landscape bursts into vibrant green with the arrival of the rains.
