Belize Weather & Rainy Season Guide — Cave Tour Safety
Planning your trip around Belize's weather? Understand dry vs rainy season, river water levels, and safety protocols for cave tours.
Understanding Weather & Seasons in Western Belize
Belize enjoys a subtropical climate with average year-round temperatures between 75°F and 88°F (24°C to 31°C). In the Cayo District, surrounding hills and forests keep night temperatures comfortable.
Whether you are planning to trek to ATM Cave or relax in San Ignacio, knowing how weather affects tours helps you plan with confidence.
The Two Main Belize Travel Seasons
Dry Season (December – May)
Warm, sunny days with low humidity and clear river water. Ideal for climbing pyramids at Xunantunich and Caracol, as well as easy cave swims.
Green / Rainy Season (June – November)
Lush green landscapes, fewer tourist crowds, and tropical afternoon showers that cool off the jungle. Rivers flow fuller and nature comes alive.

Belize Weather — Frequently Asked Questions
Does it rain all day during the rainy season in Belize?+
Rarely! In Belize, "rainy season" usually means a quick, heavy tropical shower in the late afternoon or night, followed by bright sunshine. Full days of continuous rain are uncommon outside of tropical depressions.
What happens if rain floods ATM Cave on the day of my tour?+
Safety is always paramount. The Belize Institute of Archaeology continuously monitors water levels at the cave mouth. If heavy rainfall causes high water levels, the cave is temporarily closed. When this occurs, Ian Burns will instantly pivot your itinerary to safe open-air ruins (like Xunantunich or Cahal Pech) or a rain-proof cave canoe trip.
What is the absolute best month to visit San Ignacio, Belize?+
February through April offers the driest weather, comfortable temperatures (~82°F), and crystal-clear water at Rio On Pools and Barton Creek Cave.
