December marks the heart of the dry season in Costa Rica, particularly on the Pacific coast and in the northern lowlands. This period typically experiences minimal rainfall, abundant sunshine, and lower humidity, creating ideal conditions for outdoor activities. In contrast, the Caribbean side of the country may still see some rainfall during December, though generally less than other months. Temperatures vary by elevation, with coastal regions enjoying warmth while mountainous areas offer cooler conditions.
Understanding the prevailing climatic conditions during this specific time is crucial for travelers planning trips. Choosing the right time of year to visit significantly impacts the experience, affecting potential activities like hiking, wildlife viewing, and watersports. Historically, December has been a popular time for tourism in Costa Rica due to the pleasant weather in many areas, contributing to the country’s economy and allowing visitors to enjoy the diverse ecosystems without the hindrance of heavy rain. This predictable dry season provides an optimal window for exploring the country’s renowned biodiversity.
