Mexico Climate

The Tropic of Cancer divides the Mexico climate into temperate and tropical zones. North of it, cooler temperatures prevail during the winter months. To the south, temperatures generally are constant, but vary, depending upon elevation. Areas south of the Tropic of Cancer with low elevations, which include the southern coastal plains and the Yucatan Peninsula, have an annual median temperature between 75 F and 82 F. Temperatures remain high throughout the year with less than a 10 F difference in median temperature between winter and summer.

As elevation rises toward the central plateau, yearly average temperatures range from about 61 F to 68 F. If you are living at this altitude, expect relatively constant temperatures throughout the year. North of the Tropic of Cancer, though, temperature swings are much larger.

Most of the country experiences a rainy season from June to mid-October and significantly less rain during the remainder of the year. February and July generally are the driest and wettest months, respectively.

Hurricanes affect regions of both coasts from June through November. West coast hurricanes are often less violent than those affecting Mexico’s eastern coastline. Earthquakes are also very common. The country’s Pacific coast is part of the earthquake-prone “Ring of Fire” that frequently generates very large earthquakes. Volcanic eruptions also occur in the central-southern part of Mexico.
