A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Mexico City varies very significantly throughout the year.

The wetter season lasts 4.4 months, from May 28 to October 9, with a greater than 41% chance of a given day being a wet day. The chance of a wet day peaks at 79% on July 3.

The drier season lasts 7.6 months, from October 9 to May 28. The smallest chance of a wet day is 2% on December 8.

Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 79% on July 3.

The transitions to and from daylight saving time are indicated by the 'DST' labels.


We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

The perceived humidity level in Mexico City, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, remaining a virtually constant 0% throughout.

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

The average hourly wind speed in Mexico City does not vary significantly over the course of the year, remaining within 0.4 miles per hour of 2.5 miles per hour throughout.

The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands.

The predominant average hourly wind direction in Mexico City varies throughout the year.

The wind is most often from the south for 5.0 days, from March 5 to March 10; for 2.3 months, from March 12 to May 22; and for 2.5 months, from December 8 to February 22, with a peak percentage of 39% on April 2. The wind is most often from the north for 1.6 weeks, from May 22 to June 2 and for 2.2 months, from October 1 to December 8, with a peak percentage of 46% on October 29.

Solar Energy

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.

The average daily incident shortwave solar energy experiences some seasonal variation over the course of the year.

The brighter period of the year lasts for 2.8 months, from March 7 to June 2, with an average daily incident shortwave energy per square meter above 6.8 kWh. The brightest day of the year is April 19, with an average of 7.3 kWh.

The darker period of the year lasts for 2.5 months, from November 8 to January 25, with an average daily incident shortwave energy per square meter below 5.5 kWh. The darkest day of the year is December 22, with an average of 5.0 kWh.

Data Sources

This report illustrates the typical weather in Mexico City, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.

Temperature and Dew Point

There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Mexico City.

For each station, the records are corrected for the elevation difference between that station and Mexico City according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

The estimated value at Mexico City is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Mexico City and a given station.

The stations contributing to this reconstruction are: Benito Juárez International Airport (97%, 5.9 kilometers, east) and Licenciado Adolfo López Mateos International Airport (3.2%, 47 kilometers, west).

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.

All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.

Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.

Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
