Belize is subject to the Atlantic hurricane season, so expect June through early November to be on the wetter side. Thankfully, Belize is spared from most major tropical storms. But if you are planning to tackle a lot of activities, low season is a gamble. When rains are heavy, roads and rivers on the mainland may be compromised. It’s not uncommon for Maya sites and caves to be closed due to flooding. December through April is definitely the high season in Belize. The biggest influx of visitors is around the end of the year and Easter week. May is also a good time to visit, when things begin to mellow and businesses offer specials as they scale down for the impending slow season. Expect some restaurant closures and scaled-back staff at resorts during September and October, when many local businesses give their employees time off, take their own vacations, and gear up for the upcoming high season.
