Where should you go in Costa Rica in may when it comes to the weather?

Remember:
The climate in Costa Rica in may ranges from good to very bad depending on the region and city.

May is the beginning of the rainy season. Paradoxically, the rains do not refresh the atmosphere because the heat is still strongly felt. As some areas receive more rainfall than others, the climate throughout May in Costa Rica is partially suitable.

The Costa Rican East Coast in May

The temperature climbs a notch and the heat continues to be felt, especially in the middle of the day when the thermometer can reach 34° C. The days are still magnificent, but due to an increase in precipitation, sporadic rains occur without warning, especially in the evening. This can spoil night outings.

The Center of Costa Rica in May

If planning a trip to the capital, have waterproof clothing within reach. The weather in Costa Rica throughout May on the central plateau is characterized by misty mornings followed by rainy afternoons. At nightfall, the rains intensify to the point of influencing nocturnal outings.

The West Coast of Costa Rica in May

The peaceful coastline does not escape the pangs of nature. If on the north-west coast, the intensity of the rain is still acceptable; in the south, the rains that occur day and night are so frequent that one will have to be satisfied with the cloud thinnings to enjoy the sun.
