Belize Weather for September
September temperatures in Belize average around 81°F (27°C), with highs of 86°F (30°C) and lows of 77°F (25°C). There is increasing rainfall, especially in early mornings and at night, but most days are sunny with warm temperatures. High on the list of Belize’s many charms is a very comfortable tropical climate with an average yearly temperature of 84° F (29°C). Costal sea breezes and Belize’s large tracts of jungle and rainforests provide cooling relief even in the hottest summer months while winters can be cool but never very cold. In short, the climate is pretty much near perfect.
With temperatures so consistent year round, Belize has two, rather than four seasons– the wet and the dry.
Belize’s dry season, falling between February and May, has significantly lower rainfall than the rest of the year, and when rain does come it is usually in mild, short bursts.
