The Weather in Belize

High on the list of Belize’s many charms is a very comfortable tropical climate with an average yearly temperature of 84° F (29°C).

Costal sea breezes and Belize’s large tracts of jungle and rainforests provide cooling relief even in the hottest summer months while winters can be cool but never very cold. In short, the climate is pretty much near perfect. Even in winter the temperature in Belize rarely falls below 60°F (16°C), while throughout summer the mercury sits at around 86°F (30°C). Humidity is also fairly consistent at around 85 percent.

With temperatures so consistent year round, Belize has two, rather than four seasons– the wet and the dry.

Belize’s dry season, falling between February and May, has significantly lower rainfall than the rest of the year, and when rain does come it is usually in mild, short bursts.

June through December marks Belize’s wet season, when parts of the country receive up to 150 inches of rain and the heavy, sometimes wild storms associated with the Caribbean occur, usually in the late afternoons.

The most frequent rainfall usually occurs in June or early July and is punctuated by a break in late July or August known as the "little dry."

The wet is also hurricane season, and while statistically Belize does not attract many major direct hits, it does get its share of severe tropical weather with high winds and rain.

However, Belize and its neighbours share a cooperative early warning network, and the country’s safety, evacuation and other procedures have proven to be effective.

Both the wet and dry seasons have their own pros and cons for travellers, but due to the overall mild nature of Belize’s climate, visitors can enjoy the country year round.

To assist in planning your visit here is a brief weather calendar. As with anything involving the weather it will not be 100% accurate for any given year, but it does provide a snapshot of our Belize weather.
