Belize does not have the same seasons as North American and Europe. There are only two seasons in Belize – the dry season and the wet season. The dry season lasts from December to May, and the wet season lasts from June to November. It rains almost three times as much in the southern portion of the country as it does in the north. You’ll typically experience the sunniest, nicest weather in Belize between the months of March and May.
