There is no "typical" weather in Mexico. Because some of the land is situated near the ocean, some in deserts, and some high in the mountaintops, the weather is varied, and many times, unpredictable. Here is a general rundown of the regions:

Northern West Coast

This area is generally hot and humid during the day, but the nights tend to get chilly. The farther south you travel, the hotter it will be. The rainy season is during winter.

Central West Coast

Generally the days are in the mid to upper 80's, while nighttime temperatures dip to the 60's or 70's. Summer heat can be intense in this area, as can the accompanying humidity. Summer is the rainy season for the central west coast.

Southern West Coast

Hotter than the northern area, the average temperature for this area is 90 degrees (70 at night) - and humidity that rarely dips below 50%. Summer time is rainy season for this area.

East Coast

This area is best known for its humidity in the summer and the constant rains in the winter. In fact, the intense humidity has prevented it from becoming much of a tourist attraction.

Yucatan Peninsula

This area is hot and humid, with temperatures reaching over a hundred degrees at times. Summer is the rainy season.

Central Mexico

Because much of this area is elevated a mile or so high, the temperatures and humidity rates drop considerably. You should expect about 70 degrees in the summer (cooling off to about 50 degrees at night). Winter, on the other hand, can be cold and harsh as temperatures drop to freezing levels.

The Baja Peninsula

This area can be hot as with most of the southern areas, but it also comes with a hearty wind that can last for days. Hurricanes can be a problem in this area.
