Climate overview
Temperature
The monthly mean temperature is highest in May, at 27.1 °C, and lowest in January, at 22.3 °C. These are monthly averages, not daytime maximum temperatures, and they do not describe the full range of temperatures visitors may encounter within a day.

Rain
Mean daily rainfall is highest in October, at 7.40 mm/day, and lowest in April, at 1.53 mm/day. These figures are daily averages for the respective months, not monthly rainfall totals, and the lower mean does not guarantee rain-free days.

Sunshine
Mean daily sunshine reaches its highest monthly average in April, at 11.20 hours/day, and its lowest in November, at 8.30 hours/day. These are average sunshine durations, not measures of day length or a promise of clear conditions on any particular day.

Best Travel Time Guide for Belmopan, Belize: Ideal Seasons and Weather Insights
For visitors prioritising cooler monthly averages, January is the relevant option to consider: its monthly mean temperature is 22.3 °C. This is a comparison of monthly averages, not a forecast of daytime highs or a guarantee about the temperature on travel dates.

For outdoor plans shaped around average sunshine duration, April has the highest monthly mean at 11.20 hours/day, while November has the lowest at 8.30 hours/day.
