The climate of Mexico is very diverse.[1] The Tropic of Cancer effectively divides the country into temperate and tropical zones. Land that is north of the twenty-fourth parallel experiences lower temperatures during the winter months. South of the twenty-fourth parallel, temperatures are fairly consistent all year round and vary solely as a function of elevation. The north of the country usually receives less precipitation than the south.

By region

Areas south of the twenty-fourth parallel with elevations up to Script error: No such module "convert". (the southern parts of both coastal plains as well as the Yucatán Peninsula), have a desert climate and a yearly median temperature between Script error: No such module "convert".. Temperatures here remain high throughout the year, with only a Script error: No such module "convert". difference between winter and summer median temperatures. Although low-lying areas north of the twenty-fourth parallel are hot and humid during the summer, they generally have lower yearly temperature averages (from Script error: No such module "convert".) because of more moderate conditions during the winter.

Between Script error: No such module "convert"., one encounters yearly average temperatures between Script error: No such module "convert".. Towns and cities at this elevation south of the twenty-fourth parallel have relatively constant, pleasant temperatures throughout the year, whereas more northerly locations experience sizeable seasonal variations. Above Script error: No such module "convert"., temperatures drop as low as an average yearly range between Script error: No such module "convert". in the Cordillera Neovolcánica. At Script error: No such module "convert"., Mexico City (primarily subtropical highland climate) has a yearly median temperature of Script error: No such module "convert". with pleasant summers and mild winters. The city's daily highs and lows for May, its warmest month, average at Script error: No such module "convert"., while for January, its coldest month, at Script error: No such module "convert"., respectively.

Rainfall varies widely both by location and season. Arid or semiarid conditions are encountered in the Baja California Peninsula, the northwestern state of Sonora, the northern altiplano, and also significant portions of the southern altiplano. Rainfall in these regions averages between Script error: No such module "convert". per year, although even less in some areas, particularly in the state of Baja California. Average rainfall totals are between Script error: No such module "convert". in most of the major populated areas of the southern altiplano, including Mexico City and Guadalajara. Low-lying areas along the Gulf of Mexico receive in excess of Script error: No such module "convert". of rainfall in an average year, with the wettest region being the southeastern state of Tabasco, which typically receives approximately Script error: No such module "convert". of rainfall on an annual basis. Parts of the northern altiplano, highlands and high peaks in the Sierra Madres receive yearly snowfall. Citlaltépetl, Popocatépetl and, Iztaccíhuatl continue to support glaciers, the largest of which is the Gran Glaciar Norte.

Mexico has pronounced wet and dry seasons. 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. Mexico City, for example, receives an average of only Script error: No such module "convert". of rain during February but more than Script error: No such module "convert". in July. Coastal areas, especially those along the Gulf of Mexico, experience the largest amounts of rain in September. Tabasco typically records more than Script error: No such module "convert". of rain during that month. A portion of northwestern Baja California has a Mediterranean climate influenced by the California Current, with a rainy season that occurs in winter and coastal regions receiving considerable fog. Another area of the Mediterranean climate as a result of elevation occurs in the interior of Sonora.

Mexico lies squarely within the hurricane belt, and all regions of both coasts are susceptible to these storms from June through November. Hurricanes on the Pacific coast are often less violent than those affecting Mexico's eastern coastline. Several hurricanes per year strike the Caribbean and Gulf of Mexico coastline, however, and these storms bring high winds, heavy rain, extensive damage, and occasional loss of life. Hurricane Gilbert passed directly over Cancún in September 1988, with winds in excess of Script error: No such module "convert"., producing major damage to hotels in the resort area. It then struck northeast Mexico, where flooding from the heavy rain killed dozens in the Monterrey area and caused extensive damage to livestock and vegetable crops. Template:Gallery cleanup
