December in Belize typically offers pleasant weather conditions, marking the beginning of the dry season. Temperatures range from the mid-70s to mid-80s Fahrenheit (low 20s to high 20s Celsius), with lower humidity than the wetter months. Rainfall is significantly reduced compared to the summer and fall, creating ideal conditions for outdoor activities. Nights can be cool, especially inland, sometimes dipping into the 60s Fahrenheit (high teens Celsius).
This period is considered a peak tourist season. The drier weather facilitates exploration of rainforests, Mayan ruins, and the extensive cave systems. The calm seas and excellent visibility also create optimal conditions for diving and snorkeling along the Belize Barrier Reef, the second-largest barrier reef in the world. Historically, December has been a popular time for visitors seeking comfortable temperatures and sunshine after escaping colder climates in the northern hemisphere.
