image Belize Weather and Climate The temperature in Belize is a major draw for many visitors who come to this country looking for warm, tropical weather and amazing natural beauty. Certainly these travelers will not be disappointed, as the warmest months may see daily temperatures of more than 95 Fahrenheit cooled along the coastal regions by the breezes off the Caribbean. The interior of the country lacks the cooling Caribbean breezes of the coast, however, and tends to stay between 5 and 10 degrees warmer at all times. In the winter, temperatures drop no lower than about 60 Fahrenheit, providing a pleasant relief from the heat of the summer months. Water temperatures also stay warm, only varying between 75 and 85 degrees Fahrenheit year-round.
