The temperature in Honduras does not change dramatically by the season, perhaps 5°C throughout the year. Instead, the temperature is entirely dependant on the elevation. For instance, the mountainous interior ranges from 16°C to 20°C, and is a little warmer in the dry season. Tegucigalpa, at 975m, has a temperate climate, with temperatures between 24°C and 29°C during the day in the dry season (they’re a bit cooler in the rainy season). The coastal lowlands on the Pacific and Caribbean sides are warmer and more humid year-round. Their temperatures range from 28°C to 32°C in the dry season; they’re about 3°C cooler (and more comfortable) in the rainy season.
In general, the rainy season in Honduras runs from May to November in the interior and from September to January along the north coast and Bay Islands (with a chance of severe storms any time of the year). Heavy rains can cause flooding in the lowlands and mudslides in the mountains, and both can cause serious damage and impede travel. Hurricane season is from August to November; direct hits are uncommon, but are devastating when they do. Travelers should take evacuation orders very seriously.
When to go
Like most tropical countries, Honduras experiences a rainy season and a dry season, known locally as invierno (winter) and verano (summer), respectively. In the interior, especially the west and south, the rainy season runs roughly from May to November. Rains usually come in the afternoon and last an hour or so. On the north coast and Bay Islands, the rainy season is later, around September to December, with nortes (‘northerners’, cool storms from the north) possible into February. Hurricanes are most likely from September to October, though they rarely hit Honduras directly. However, even a far-off hurricane can send heavy rain Honduras’ way and can cause flooding or minor mudslides.
Travel is easier during the dry season, especially for scuba diving and trips to La Moskitia. Then again, the forests and countryside are more lush during the rainy season. February and March are good months to visit because the weather is fairly stable across the country; the trails and roads are drying out but the trees and underbrush are still full and green.
