Unlike most of the United States and Canada, Belize does not go through a yearly cycle of four seasons that alternate periods of cold and heat. Instead, Belize enjoys a sub-tropical climate similar to that in South Florida, noted for its balmy temperatures, rich abundance of flora, and steady coastal breezes.
Humidity in Belize is fairly consistent at around 85%. Large tracts of rainforest and jungle help provide cooling during hot periods, but temperatures rarely rise above 86°F (30°C). In very high elevations, temperatures may drop into the mid-50s Fahrenheit (13°C), but Belize does not receive any ice or snow.
Instead of four seasons, Belize has two different “seasons” that each last around six months. From approximately mid-November until May, Belize goes through a “dry” season with relatively low precipitation. The period from April until the beginning of November is known as the “green” season where precipitation levels are higher, usually in the form of overnight showers and brief yet strong downpours during the hottest part of the afternoon.
In between these two seasons is a micro-season. The period that begins in late July and usually runs through August is known as the “Little Dry” season because precipitation levels drop.
