The Pacific and Caribbean coasts of Costa Rica see similar weather patterns but get different amounts of rainfall depending on the time of year.

    Within Costa Rica’s borders lie coastal plains, active volcanoes, mountainous areas, and thick jungles – each with their microclimates. 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.

    Weather patterns in Costa Rica

    Costa Rica’s diverse landscapes give rise to weather changes. The high-altitude Central Valley and southern regions experience temperate conditions with milder year-round temperature levels compared to the sweltering heat of the lowland coastal regions.

    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.

    Come May, predictable rains cause a shift in the weather as the Intertropical Convergence Zone swings north drenching Costa Rica through November. Getting over 70% of yearly rainfall, the “green season” sees increased cloud coverage and sudden torrential rainstorms.

    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.

    Green Season in Costa Rica

    Fewer people visit Costa Rica from December to April. Rates are lowered to entice value-seekers interested in overcast vistas. Early dry spells between December and January see the return of migratory whales. Some people make travel plans to spot humpback whales offshore.

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.

Though this period presents the best time to enjoy the outdoors with February and March being the best months, there are advantages when you travel to Costa Rica at other times as well.

Costa Rica’s climate in March is just right to visit many areas without experiencing extreme heat or rainfall. Global traffic to Costa Rica depends on the weather. Fewer global tourists arrive to see natural sights on the Caribbean side of Costa Rica as compared to those arriving during the peak season between December and January when the weather is good.

    Traveling during the green season is a great option to see the lush green landscapes in Costa Rica. This is when the rainy season officially begins in May, and this rainy season lasts until November. You’ll find similar weather conditions in the rest of Costa Rica during this period. Wildlife is most active following the rainy season months. Although you cannot predict the weather and some shower activity is expected, daily precipitation tends to be for short periods.
