Mexico’s weather varies significantly by season and by region.
The weather and climates in Mexico are affected by a combination of the season, what part of Mexico you are in, and what altitude is there. This guide explains Mexico’s climates and weather by season and region and contains links to relevant articles about Mexico’s climates.

Hottest Months: The hottest months are April & May in the South, and July to September on Pacific Coast (Including Baja), and extremely hot in the Yucatan May to September.
Coolest Months: Vary by region, but generally December, January, February; the Yucatan can still experience hot weather even in the coolest months.
Rainy Season in Mexico: Mexico’s Rainy season runs from May to September (sometimes extends to October) each year. Most regions south of the Tropic of Cancer (near Mazatlan) are affected.

Climates by Region in Mexico
How Regions and Altitude Affect the Climate in Mexico
See Mexico: A Land of Three Lands for detailed information about how region and altitudes affect the climate across Mexico.
Northern Mexico is a desert region that features hot and dry weather, although cooler months can experience temperatures that drop to freezing overnight. Away from coastal areas, the weather in Mexico’s northern states in low-lying areas is hot and dry, and in elevated areas (like Guadalajara) the temperature is mild all year-round.
Inland central Mexico will be warm or hot (and dry) during the day, although evenings can get cool, so pack a pull-over that you can use during the early mornings and after sundown, when the difference in extremes of temperature can be felt quite acutely, especially during the winter months.
In Mexico’s southern regions (including Mexico City), the climate will be similar to that in central Mexico, but remember to keep in mind that elevated areas (including most of the colonial cities in this region) will be cooler and more temperate. The climate gets distinctly hotter and more humid as you travel deeper into the south / southeast and the Yucatan Peninsula, and when you descend from the highland cities towards the coasts.
Hot and humid, especially June thru August. During these months, expect the days to be blisteringly hot, with monsoon-like downpours of rain in the early evening (they usually pass within a short time and leave the night dry and cooler). Hurricane season (June-October, sometimes extends into November) usually brings wetter weather and makes weather forecasting less accurate. The high season in this part of Mexico is December through May as these are the months with the most temperate and driest weather.
Baja California Peninsula
The stretch of land immediately south of California, USA, is Baja California (‘Baja‘ means ‘Lower’), and the weather here can be divided into two distinct categories: hot deserts inland and cooler near the oceans. Rainy days are rare outside of the ‘rainy season’ during September, which is why many golfers come here to play.
