San Ignacio in September

December through April brings San Ignacio's dry season — perfect weather for temple climbing and cave exploring. Temperatures hover around 80°F during the day, dropping to comfortable 65°F at night. This is peak season, so book accommodations early and expect higher prices. January and February offer the sweet spot of great weather without Christmas crowds. You'll pay regular rates and have ruins mostly to yourself on weekdays. The Macal River runs lower, making swimming holes more accessible but cave tubing less exciting. March heats up significantly, with temperatures reaching 90°F by afternoon. Early morning starts become essential for comfortable hiking. But the wildlife viewing improves as animals gather around water sources. April marks the transition to rainy season. You'll catch occasional afternoon showers but still enjoy mostly sunny days. Prices drop and crowds thin out, making this a budget traveler's favorite time. May through November brings heavy rains and humidity that turns jungle hikes into steam baths. Roads to remote ruins become impassable, and some tour operators shut down completely. But the rainforest explodes with life — perfect for serious birders and those who don't mind getting soaked. Accommodation prices hit rock bottom, with some places offering 50% discounts. Hurricane season (June-November) occasionally affects Belize, though San Ignacio's inland location provides some protection from the worst storms.
