When to go
Situated well within the tropics, Rio San Juan has a typical tropical climate with high temperatures all year round. May - Nov is rainy season, but places on the eastern coast, the Caribbean side, tend to be rather wetter, and to have a longer rainy season, than those on the Pacific coast to the west. There’s a risk of tropical storms or hurricanes Jun - Nov.
