With a sub-tropical climate and an advantageous location near the equator, Belize is blessed with year-round sun and balmy temperatures. With lots of lush nature and pristine scenery bounding with wildlife, Belize enjoys ample rainfall and even the occasional thunderstorm.
Situated between Mexico’s Yucatan Peninsula, Guatemala, and the Caribbean Sea, Belize is located just south of the Tropic of Cancer. This allows Belize to enjoy ample amounts of sun and warm temperatures even when other latitudes have begun to experience the first chills of autumn.
More than a third of Belize is set aside as a national park or protected nature reserve. The abundance of jungle, rainforest, and verdant flora are proof positive that Belize is a well-hydrated country. The relatively high humidity is popular with many visitors for its ability to control allergies, improve skin suppleness, and relieve sinus and congestion issues.
Unlike more temperate countries, Belize effectively has two seasons: the dry season and the green season. Neither season is precisely defined, as there are occasional rainstorms during the dry season and long stretches of sunny skies during the green season.
The dry season runs from approximately early November to mid-May. You can expect to see rain showers overnight and in the early morning while breezes bring refreshing relief. The dry season is perfect for exploring isolated Maya ruins in the jungle, canoeing on one of the country’s many pristine rivers, and enjoying the popular cave tubing expeditions.
The dry season is similar to summer in more temperate latitudes, so be sure to bring plenty of sunscreen, hats, sunglasses, and other forms of protection for fair skin. Months like December and January which are very cold elsewhere see little in terms of temperature drops, but there are some nights when snuggling up with a warm jacket or sweatshirt is required. Even during the height of “winter”, you’ll never have to deal with snow, ice, sleet, or blizzards in Belize.
The green season coincides with the low season for tourism, making it an ideal time to visit for budget-conscious travelers and visitors wanting to avoid crowds. Humidity levels are higher during the green season and regular rainfall keeps the rainforests, jungles, and lowlands vibrant and healthy. Despite the name, the sunshine during the green season can still be very strong, so visitors with fair skin are encouraged to maintain normal protection protocols against sunburns and UV damage.
