Daily Chance of Precipitation
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. Puerto Vallarta experiences very significant seasonal variation in monthly rainfall.
The rainy period of the year lasts for 276 days, from May 19 to February 19, 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 10.4 inches.
The rainless period of the year lasts for 89 days, from February 19 to May 19. The least rain falls around April 16, with and average total accumulation of 0.1 inches.
Average Monthly Rainfall
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.
Puerto Vallarta experiences very significant seasonal variation in the perceived humidity.
The muggier period of the year lasts for 253 days, from April 9 to December 18, during which time the comfort level is muggy, oppressive, or miserable at least 51% of the time. The muggiest day of the year is August 23, with muggy conditions 100% of the time.
The least muggy day of the year is January 24, with muggy conditions 34% of the time.

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 Puerto Vallarta does not vary significantly over the course of the year, remaining within 0.4 miles per hour of 3.3 miles per hour throughout.
Average Wind Speed
The predominant average hourly wind direction in Puerto Vallarta varies throughout the year.

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 significant seasonal variation over the course of the year.

Temperature and Dew Point
There is only a single weather station, Licenciado Gustavo Díaz Ordaz International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Puerto Vallarta.
At a distance of 7 kilometers from Puerto Vallarta, 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 are corrected for the elevation difference between the station and Puerto Vallarta 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.
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.
