Overall, the weather across Costa Rica is humid with a regular rainy season and rains falling intermittently at other times of the year. The tropical climate is best for taking in the sun’s rays, but you can plan a custom trip to Costa Rica during the wet or dry season and still ensure good weather.

    The Caribbean coastal plain experiences tropical weather identified by the oppressive heat. Heavy rainstorms prevail from April through November. On the other hand, the Guanacaste Province on the northwestern Pacific coast enjoys a distinct dry season with less rain.

    To truly experience everything Costa Rica has to offer, visitors can benefit from the unique weather in each region. The Central Valley’s pleasant environment suits city journeys to the colorful capital of San Jose. For wildlife watching, the rainforests invite exploration during wetter months when wildlife species are most active. Beach lovers head to the Pacific coast in the dry season from December to April.

    Coastal humidity heightens with temperatures reaching 30° C under grey drizzly skies. Mountains and highlands stay milder yet regular storms can affect visibility. Adventurous tourists can still pursue waterfall hikes and ziplining in the middle of rich tropical landscapes. However, some lowland roads might become impassable for a brief duration.

    The rainiest months are September and October when daily downpours turn dirt roadways into mud paths. Rivers overflow bridges and swimming holes transform into raving whitewater rapids. Restricted dry spells offer brief windows to spend time along the coast or trek without getting drenched.

    Nature reacts throughout the rainy season with lively blooms filling the humid air with heady scents. Nevertheless, steaming jungles harbor fungal infections, so protective clothes are required. Cover exposed skin and use repellents including at dawn and dusk when insect activity rises. With the right preparation, tapping the rainy season’s natural rhythms can yield wonderful discoveries off the beaten path.

With perseverance, some elusive night-time forest inhabitants like boa constrictors and kinkajous can be spotted. Wildlife grows with the restoration of developmental patterns offering unobstructed viewing opportunities.

    Coastal climates are perfect for diving along the turbid reefs that expose rare animals looking for shelter amid coral networks. Underwater caves shelter seahorses and schools of colorful fish that are not seen during the high season. Those who adapt well to the changing weather can experience the same potential for adventure tours in the season but gain the benefit of paying lower rates.
