By June, Costa Rica is well into the rainy season: daily rain is common, if not guaranteed, though showers often last just an hour or two. Exceptions to the rule: Arenal is now in high dry season, although as one of the rainier areas of Costa Rica, you may still get caught in the occasional shower.

In Costa Rica, the duration of rain showers depends heavily on the season and the specific microclimate, but they are typically intense and short-lived. During the "Green Season" (May to November), you can expect a predictable pattern: bright, sunny mornings followed by a heavy tropical downpour in the mid-afternoon that lasts for 30 to 90 minutes. These "liquid sunshine" bursts are often followed by clear, cool evenings. However, on the Caribbean coast (Puerto Viejo/Tortuguero), rain can be more unpredictable and may last for several hours or even a few days during peak wet periods. In the Cloud Forests (Monteverde), the rain often takes the form of a constant, fine mist known as pelo de gato (cat's hair) rather than a heavy shower. For a traveler in 2026, the "pro-tip" is to plan your outdoor adventures for the morning and use the afternoon rain as a perfect excuse for a nap or a long lunch, as these tropical showers are vital for keeping the jungle lush and the wildlife active.
