May marks the transition between Costa Rica’s dry season and the “green season,” or rainy season. This transitional period typically brings sunshine in the mornings with increasing chances of afternoon showers or thunderstorms, particularly in the inland and mountainous regions. Coastal areas generally experience less rainfall. Temperatures remain warm, averaging in the mid-80s Fahrenheit (around 30 degrees Celsius), with humidity levels gradually rising.
Understanding the climatic nuances of this period is beneficial for travelers planning trips to Costa Rica. The shoulder season offers potential advantages such as lower prices and fewer crowds compared to the peak dry season. The increased rainfall revitalizes the lush landscapes, creating vibrant scenery. Additionally, the afternoon showers often leave the air refreshed and cooler for the evening. Historically, this transition period signifies the return of rains essential for the country’s diverse flora and fauna.
