Costa Rica has a tropical climate. The temperature varies depending on elevation, so the coastal lowlands have average temperatures between 71 degrees and 81 degrees, while it’s 20 degrees lower in the high mountains.
The seasons are divided into two periods, summer and winter, but these are different from their U.S. counterparts. In Costa Rica, “summer” is the name for the dry season, and “winter” is the name for the rainy season. Summer takes place between December and April, and winter occurs from May to November.
