The rainy season in Honduras lasts from May to November. Temperatures and humidity become higher, which can make things a bit stuffy. In the mountains, the heat is less of a problem. Some roads might close down due to the rock slides and floods.
Hurricanes and tropical cyclones often occur in Honduras as in the rest of Central America. They occur most often from August to October.
Some of the best rafting and kayaking weeks occur right after the rainy season.
