Belize Weather and Climate

If you had to sum up the climate and weather in Belize in a single sentence, it is very similar to South Florida and the Miami area. Officially, Belize has a sub-tropical climate with balmy weather year-round and an average annual humidity of 83%.

Belize is located on the Caribbean coast of Central America just south of Mexico’s Yucatan Peninsula. The hundreds of offshore islands and coastal regions are favored by trade breezes most of the year that keep humidity levels at bay.

Unlike continental North America, Belize only has two seasons, generally known as the “dry” season and the “green” season. The dry season is characterized by abundant sunshine, warm days, and slightly lower humidity levels. The dry season runs from approximately mid-November to the end of May. Daytime highs during the dry season are in the low to mid-80s Fahreinheit while nighttime lows hover between 75-79 Fahrenheit.

The “green” season runs from June to early November. Precipitation levels are higher during the green season, but daytime temperatures generally stay steady in the mid to high 80s Fahrenheit and nighttime lows are between 80-81 Fahrenheit. The heaviest rains fall in September and October, but most of the green season is characterized by early morning showers and brief thunderstorms during the hottest part of the afternoon.

The mountains and elevated locations on the mainland generally see slightly lower temperatures. Nighttime lows rarely dip below 72F and daytime highs rarely exceed the low 80s. Although temperatures can sometimes dip to the 50s in some isolated locations, the weather in Belize is generally quite warm all year-round.

Belize has four modern highways that connect the biggest metropolitan areas of the country, but smaller villages and remote outposts still rely on dirt and gravel roads. Following rainstorms, rivers can swell and unpaved roads may be difficult or impossible to traverse. Some popular underground attractions like Actun Tunichil Muknal (ATM) Cave may be closed during bouts of heavy rain.

Generally speaking, November to January is the coolest part of the year while May through September is the hottest part of the year, although the fluctuation between these two periods is only a matter of a few degrees Fahrenheit. As Belize never receives any snow or ice, the “winter” months are the most popular time for tourists to visit the country to escape inclement weather back at home.

Abundant sunshine and Belize’s southern latitude mean that visitors should take precautions to remain well hydrated at all times. Visitors with fair skin are strongly encouraged to use sunglasses, hats, and sunscreen to ensure a pleasant vacation in Belize.
