People often visit and decide to stay and live in Belize because the weather is so great. Living in a country that has no winter storms, no snow, no heating bill, means you will be living in paradise. When it's freezing in the US, Canada, Europe and other nations around the world it's paradise in Belize! Belize is a place where the sun shines almost every day of the year and if near the Caribbean Sea, you will find that you may not need air-conditioning with the cool Caribbean breezes that blow across the land. The temperatures in Belize vary from highs in the 90’s during the daytime down to lows of 60-70’s in the nighttime. Summers are invariably 10° cooler than other locations in Mexico and other Central American countries!
Climate: The climate in Belize is Sub-tropical, constantly tempered by trade winds. Temperatures in the coastal regions of Belize range from about 10oC (50oF) to about 35.6oC. (96oF). Belize has an annual mean temperature that varies from 81°F/ 27°C along the coast to 69°F/21°C in the hills. The coldest month is January while the highest temperatures are experienced during the month of May. Inland stations tend to have more extreme temperatures than coastal stations where the sea breeze moderates the temperature. For example average maximum and minimum temperatures at Central Farm located inland of Belize are both hotter and colder than those at the Philip Goldson International Airport along the coast of Belize.
The climate of Belize is characterized by two seasons: a dry and a rainy season. The Dry Season in Belize normally occurs during the months of February to the end of May. In Belize, most of the year’s rainfall occurs during the period June to November, that is, the Rainy Season. It is noted from the graph below that the transition from dry to the rainy is very sharp. Mean annual rainfall across Belize ranges from 60 inches (1524mm) in the north to 160 inches (4064mm) in the south. Except for the southern regions, the rainfall is variable from year to year.
Figure 1 shows the distribution of average monthly rainfall data for Belize. The data are from stations in
The onset of the rainy season begins in the early May in Toledo, progressing north to the Stann Creek, Belize, Cayo and Orange Walk District in late May, followed by Corozal District in early June. The onset was determined by the first occurrence after the1st of May in which there was more than an inch of rainfall in seven days with at least four days receiving some rainfall.
In the south the rainfall is further enhanced by the intrusion of the Inter-Tropical Convergence Zone (ITCZ) as it journeys northwards. Orographic lifting over steep slopes in the south also enhances rainfall activity. The southern region has one maximum which occurs in the month of July and is by far the wettest month.
Central Regions show a primary and secondary maxima occurring in June and September. Each of these is significantly less than the single maximum for the south.
The data for the Northern region show that rainfall is more evenly distributed during the same period with no significant variation as in the other regions.
The rainy season exhibits a break or mark decrease in the month of August with a short dry spell. This break is known as the "Mauga" season in Belize. However, this pattern is not evident in the Toledo district.
Although cold fronts affect the country from October through to April the most likely months for frontal passages are December, January and February. In December and January fronts are most likely to become stationary over Belize.
