Belize month by month

Average rainfall and the number of days with at least 1 mm of rain, 2006–2025. On this page a month counts as wet when it gets more rain than an average month in that place (more than a twelfth of its year), and dry when it gets less than half an average month. The months in between are the shoulder.

Some guides describe a short “little dry” in August; it does not show in this twenty-year record at either place, where August is as wet as the months around it.

Does the rainy season mean storms?

Not by itself — but Ambergris Caye (San Pedro) is on the hurricane map, and the two overlap here. In the 50 seasons to 2025 a tropical storm or hurricane passed within 100 miles of it in 8 of them in August, its busiest month — which is to say that in the other 42, that month was rain and nothing else. Rain is what most of a wet season is: for the storms themselves, see hurricane season in Belize and every storm since 1976.

How these numbers are made

Daily rainfall and temperature from NASA POWER (MERRA-2), averaged over 2006–2025; a rain day is a day with at least 1 mm. POWER works on a grid of about 50 km, so each place here is its neighbourhood rather than its own rain gauge: a coast, a small island or a valley under a mountain can differ from the square it sits in. The months are the part that holds; treat a single millimetre figure as an average, not a forecast. Storm counts are from NOAA’s best tracks (HURDAT2), 1976–2025.
