One of Belize’s top attractions is its balmy, subtropical climate that features an average daytime temperature of 84 degrees Fahrenheit (29 degrees Celsius).
Although summers are quite warm, coastal breezes passing over interior jungles and rainforests provide plenty of relief. There is no winter as such in Belize, as daytime highs rarely drop below 60F (16C). Even in the mountain highlands, temperatures never drop below zero. During the summertime, daytime highs average around 86 F (30 C) with a steady humidity level of around 85%. In short, Belize has near-perfect weather.
Unlike the United States or Canada, Belize only has two seasons – called the dry and green seasons.
The dry season, a period of abundant sunshine and blue skies, runs from around mid-November through May. Although rainfall is still in evidence in this lush country, most precipitation is in the form of short, mild bursts.
The green season runs from June through early November. During this period, the lush interior jungles, rainforests, and wetlands are replenished. There are occasional periods of strong storms, particularly in September and October.
June is a month of higher precipitation that normally comes in the form of overnight storms or brief yet intense downbursts during the hottest part of the afternoon. Somewhere in late July or early August, the blue skies re-appear during a period known locally as “The Little Dry.”
Although strong storms can sometimes build in the Caribbean, Belize’s sheltered position and advanced early warning network have been proven effective at safeguarding against loss of life or property.
Both the dry and green seasons offer plenty to do and see in Belize, but the balmy weather and pristine nature mean that Belize is a popular place to visit all year round.
In order to help you plan your visit to Belize, we have provided a general guide to what to expect in terms of weather on a month by month basis.
