Understanding Costa Rica’s Seasons
Before diving into Costa Rica weather by month, it’s important to understand the country’s two main seasons:
- Dry Season (December to April) – Also called verano, this period brings sunny days and minimal rain, especially on the Pacific coast.
- Green Season (May to November) – Lush landscapes, fewer crowds, and lower prices, with afternoon rain showers.
The Caribbean coast follows a different weather pattern and can be drier when the Pacific is rainy.
