Rainfall

To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day in the year. Mazatlán experiences very significant seasonal variation in monthly rainfall.

The rainy period of the year lasts for 8.4 months, from June 1 to February 11, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around September 1, with an average total accumulation of 7.1 inches.

Humidity

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.

Mazatlán experiences very significant seasonal variation in the perceived humidity.

The muggier period of the year lasts for 6.7 months, from May 7 to November 27, during which time the comfort level is muggy, oppressive, or miserable at least 28% of the time. The muggiest day of the year is September 11, with muggy conditions 100% of the time.

The least muggy day of the year is January 23, with muggy conditions 4% of the time.

Wind

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 Mazatlán does not vary significantly over the course of the year, remaining within 0.4 miles per hour of 3.2 miles per hour throughout.

Data Sources

This report illustrates the typical weather in Mazatlán, 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 is only a single weather station, General Rafael Buelna International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Mazatlán.

At a distance of 16 kilometers from Mazatlán, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records.

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

Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.

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.
