December usually arrives wet and leaves drier as the wet season begins to wind down. December temperatures in Belize fall to an average low of 71°F (22°C) with highs of 80°F (27°C) for a monthly average of around 75°F (24°C) – the perfect weather to enjoy a comfortable Christmas holiday, warm enough for swimming and with pleasantly cool evenings.
In Belize the high season for tourists corresponds roughly with the dry season: December to May. The shoulder months – especially December – receive a fair amount of rain, but not enough to scare away the multitudes of travelers who want to spend their holidays in the tropics. Most hotels and resorts are more expensive during this period.
The biggest influx of tourists comes between December 15 and January 15, and during the weeks around Easter.
