Belize has a subtropical climate. Daytime temperatures are typically in the mid-70s to mid-90s. The predictability of the dry and wet seasons has changed a bit over the past few years, but traditionally the dry season is from late November through May. The wet season runs roughly from June through October. During the dry season temperatures will be on the lower end of this range, and during the wet season they will be on the higher end.
The wet season can be a fine time to visit, as it won’t generally rain all day long. Instead it will rain part of the day and be clearer part of the day, prices will be lower, and there will be fewer tourists. In September and October, there is a threat of hurricanes, and travel is not advised during this period.
