Belmopan features a tropical monsoon climate (''Am'') under the Köppen climate classification. The city has a lengthy wet season that runs from May through January and a short dry season covering the remaining two months. As is the characteristic of several cities with a tropical monsoon climate, Belmopan sees some precipitation during its dry season. March and April are Belmopan's driest months with roughly 45 mm of rainfall observed on average during those months. Like Belize City, these are somewhat unusual months for a city with a tropical monsoon climate to have its driest months of the year. Typically the driest month for a city with this climate type is the month after the winter solstice, which in Belmopan would be January. Average monthly temperatures are somewhat constant throughout the course of the year, ranging from 23 °C to 28 °C.
