Climate

The peninsula has a tropical climate, which ranges from semi-arid in the northwest to humid in the south. Average annual rainfall ranges from less than 800 mm (30 inches) in the driest parts of the northwest up to 2,000 mm (80 inches) in the Petén Basin to the south. Rainfall varies seasonally, with August and September generally the wettest months.

Like much of the Caribbean, the peninsula lies within the Atlantic Hurricane Belt, and with its almost uniformly flat terrain it is vulnerable to these large storms coming from the east, and the area has been devastated by many hurricanes, such as Hurricane Gilbert, Hurricane Emily, Hurricane Wilma, and Hurricane Dean.

Strong storms called nortes can quickly descend on the Yucatán Peninsula any time of year. Although these storms pummel the area with heavy rains and high winds, they tend to be short-lived, clearing after about an hour. The average percentage of days with rain per month ranges from a monthly low of 7% in April to a high of 25% in October. Breezes can have a cooling effect, humidity is generally high, particularly in the remaining rainforest areas.
