Costa Rica - When to Visit

When to Visit Costa Rica

Climate guide & best times to travel

Costa Rica has a tropical climate that's actually pretty straightforward once you understand the two main seasons. The dry season (verano) runs roughly from December through April, while the rainy season (invierno) takes over from May through November. That said, the country's microclimates mean conditions can vary quite a bit depending on whether you're on the Pacific coast, Caribbean side, or up in the highlands. Temperatures tend to stay fairly consistent year-round, typically ranging from the low 20s°C to low 30s°C in most lowland areas, though it gets cooler as you climb into the mountains. The humidity hovers around 70% throughout the year, which is noticeable but not oppressive if you're prepared for it. During the rainy season, you'll usually see afternoon downpours rather than all-day rain, so mornings are often clear and perfect for activities. The Caribbean coast actually follows a slightly different pattern, with its wettest months being July and December, so it's worth considering which region you're planning to visit when timing your trip.

Best Time to Visit

Beach & Relaxation
December through April offers the most reliable sunshine on the Pacific coast, with minimal rain and calm seas. February and March are particularly dry if you want guaranteed beach weather.
Cultural Exploration
May through early December works well since you'll encounter fewer tourists and lower prices, plus morning activities are typically rain-free. The green season also means lush landscapes for photography.
Adventure & Hiking
January through April provides the best trail conditions with less mud and clearer views from mountain peaks. That said, the rainy season (May-November) brings incredible wildlife activity if you don't mind getting wet.
Budget Travel
May through November is shoulder and low season, meaning significantly cheaper accommodation and tours. September and October see the fewest tourists, though rainfall is at its peak.
