The climate of Belize

Belize is a geographically diverse Central American country that lies between Mexico and Guatemala, facing the Caribbean Sea to the east. With a tropical monsoon climate, it experiences high temperatures throughout the year. The average temperature of the coldest month exceeds 18°C (64.4°F), reflecting the inherent warmth of tropical climates. A distinguishing feature of this climate type is the monsoon season, marked by a pronounced seasonal reversal of wind direction and significant variations in rainfall. The wet season in Belize is typically very rainy, contrasting the drier periods of the year. The rainfall is unevenly distributed, with the Maya Mountain region in the south recording up to 4500mm (177.17") annually, while the northern regions receive less than half of that, about 1500mm (59.06") per year. Humidity levels remain consistently high, typically ranging from 83% to 85%.

The Best Time to Visit Belize

The ideal time to visit Belize falls during the dry season, which runs from late November to mid-April. During this period, rainfall is significantly reduced, and the temperatures are more manageable, ranging from 21°C (69.8°F) to 29°C (84.2°F), making outdoor activities such as hiking, snorkeling, and exploring Mayan ruins more enjoyable. Additionally, the milder conditions during this period provide an opportunity to observe a wide array of wildlife, particularly in the Cockscomb Basin Wildlife Sanctuary and the Blue Hole National Park. The trade winds during these months also provide excellent conditions for sailing and other water-based activities along the Belize Barrier Reef.

The Worst Time to Visit Belize

The most challenging period to visit Belize is during the height of the wet season, generally from June to November. These months experience heavy and frequent rainfall, particularly in the southern and inland regions of the country. Rainfall peaks in June and September, and the humidity level rises, sometimes making outdoor activities uncomfortable. Additionally, the Atlantic hurricane season coincides with this period, with a risk of tropical cyclones affecting the country, especially between August and October. However, those who enjoy birdwatching might find the rainy season advantageous, as many species breed during this period.
