Belize Weather Overview
Officially, Belize is classified as having a subtropical climate very similar to that found in central and southern Florida. Unlike more temperate zones, Belize does not experience the traditional four seasons. Instead, Belize has two seasons, one known as the “dry” or “high” season and the other known as the “green” or “low” season.
The high season, so-called because it is when many tourists visit the country, runs from approximately late November until the end of May. The high season corresponds with winter in more northerly climes but temperatures in Belize remain steady between the mid-80s (Fahrenheit) to low 90s in the daytime and mid to high 70s at night. Both seasons experience a consistent level of humidity all year around of about 85%.
The green season runs from approximately the beginning of June through the end of November, although there is a period running from mid-July to early August known as the “little dry” that provides a respite from the higher precipitation levels that characterize the green season. Despite corresponding to what would be summer in more northern regions, temperatures during the low season are only slightly higher with highs in the upper 80s to mid-90s during the daytime and mid to high 70s at night. Rainfall during the green season is most prominent in the early overnight hours and during brief but often intense rain showers during the hottest part of the afternoon.

Despite the names of the two seasons, Belize’s lush jungles, pristine rainforests, and exotic wildlife thrive due to consistently generous precipitation amounts all year round. The months with the highest amount of rainfall are usually May before the “little dry” period and late September into October. Occasionally, strong storms develop in the Caribbean that can affect Belize, but the country has a modern advanced warning system to handle such events.
Due to its location, the Caribbean Sea maintains year-round warm water temperatures suitable for swimming, scuba diving, snorkeling, and other marine activities. Temperatures along the coast tend to be a few degrees cooler than the interior thanks to consistent sea breezes. Some higher elevations in the western part of Belize, especially the Maya Mountains and the Mountain Pine Ridge Forest Reserve, enjoy temperatures several degrees cooler than the surrounding area. Some parts of northern Corozal District in the north of Belize enjoy cooler temperatures due to air masses that push south from over the border in Mexico.
