Mexico weather patterns change from one area to the next. A key factor to the difference here is altitude. Rainfall plays another important role in determining just what the Mexico weather will be like. Most of the country is much warmer than the United States.
In the coastal areas and the Yucatan Peninsula, you will be in the warm tropics and subtropics, which means more humidity and a lot more heat. This is especially true of the lower regions of the coutry. Here, you are likely to see annual temperatures on average of 77°F to 81°F (25°C to 27°C).
The hottest it will get will be well over 100°F (38°C) degrees. The lowest temperatures in these regions will be about 60°F (15°C) degrees found in areas over 3000 feet (914m) of altitude.
Mexican climate does have cooler locations, which are located between 3000 and 6000 feet (914m to 1829m) above sea level. Mexico City, for example, is a cooler city because it is located here. It’s a bit cooler at this altitude with temperatures at about 70°F (21°C) degrees for an annual average. The mountain regions are cooler still, with the tops of the mountain peaks covered with snow.
Most of Mexico does not receive a lot of rain at any point during the year. The heaviest rains come during the summer months of June through September, but even then, it is not a large amount. In areas like Tabasco and Chiapas you will see the most rain, about 200 inches (508cm) per year. In locations such as Baja California, there is just about no rain. In most other areas, expect between 39 and 118 inches (100 to 300cm) per year.
For many Mexico weather is comfortable to hot. Your location will make the largest difference in the climate that you experience. You may want to live in areas of a bit lower temperature, but if you live in coastal towns, the breezes coming off the ocean help to make the warmer temperatures comfortable, too.
One thing to watch out for is if you are on the Eastern coast, as you are more likely to be hit by hurricanes. If you are one the western coast, there’s also a possibility for severe weather, but as a general rule it does not compare to conditions on the eastern coast.
