Costa Rica's seasons
An overview of the whole country in terms of the seasons.
December to April
From December to late April/early May Costa Rica gets relatively little rain. Because of this, these months are generally the more popular and busier times to visit – especially Christmas and Easter. April and May are the less busy months within this period.
Consider booking as early as possible to stand more chance of getting your first choice of accommodation.
May, June and November
It begins to rain a little more from May. As a rough rule mornings tend to be sunny and any rain often comes as an afternoon downpour before clearing once again. It’s not all rain, rain, rain.
Also on the plus side, there are now fewer visitors and hotel availability is better. If you’re going off the beaten track and self-driving, we’d recommend a 4x4 as the roads could be muddy.
July to October
While this is the rainy season, it’s really only September and October which tend to be a write-off for most travellers as many hotels close and roads can be quite bad.
July and August are still a good time to visit and you get sunny times on most days. As well as being quieter, the flowers are blooming and it’s a great time for birds and butterflies. Also it’s a perfect time for river rafting.
