Belize has a tropical climate with pronounced wet and dry seasons, although there are significant variations in weather patterns by region. Temperatures vary according to elevation, proximity to the coast, and the moderating effects of the northeast trade winds off the Caribbean. Average temperatures in the coastal regions range from 24° C in January to 27° C in July. Temperatures are slightly higher inland, except for the southern highland plateaus, such as the Mountain Pine Ridge, where it is noticeably cooler year round. Overall, the seasons are marked more by differences in humidity and rainfall than in temperature.
Average rainfall varies considerably, ranging from 1,350 millimeters in the north and west to over 4,500 millimeters in the extreme south. Seasonal differences in rainfall are greatest in the northern and central regions of the country where, between January and April or May, fewer than 100 millimeters of rain fall per month. The dry season is shorter in the south, normally only lasting from February to April. A shorter, less rainy period, known locally as the "little dry," usually occurs in late July or August, after the initial onset of the rainy season.
Hurricanes have played key--and devastating--roles in Belizean history. In 1931 an unnamed hurricane destroyed over two-thirds of the buildings in Belize City and killed more than 1,000 people. In 1955 Hurricane Janet leveled the northern town of Corozal. Only six years later, Hurricane Hattie struck the central coastal area of the country, with winds in excess of 300 kilometers per hour and four-meter storm tides. The devastation of Belize City for the second time in thirty years prompted the relocation of the capital some eighty kilometers inland to the planned city of Belmopan. The most recent hurricane to devastate Belize was Hurricane Greta, which caused more than US$25 million in damages along the southern coast in 1978.
