Costa Rica Weather: What to Expect During Your Vacation in Riu Guanacaste

Costa Rica enjoys a tropical climate year-round, making it a great destination in any season. Temperatures remain warm throughout the year, while the main difference is the amount of rainfall.

Thanks to its diverse geography, weather conditions can vary between regions, so every part of Costa Rica offers a unique experience.
