Temperature in Belize: Month-by-Month Guide for Travelers
Belize is warm year-round, but the way that warmth feels changes depending on where you are — the Caribbean coast, the inland valleys, or the Maya Mountains. As a Belizean tour guide, I’ve felt the cool December breezes on the river, the heavy humidity of June afternoons, and the relief when a sudden rain breaks the heat. Visitors often ask: “How hot does Belize get?” or “Is it always beach weather?” Here’s what you can expect.
