Cloud Cover Categories
Ta’if does not experience significant seasonal variation in the frequency of wet days (i.e., those with greater than 0.04 inches of liquid or liquid-equivalent precipitation). The frequency ranges from 1% to 4%, with an average value of 2%.
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 4% on May 6.

Sunrise & Sunset with Twilight
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 Ta’if, 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, staying within 1% of 1% 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 Ta’if experiences mild seasonal variation over the course of the year.
The windier part of the year lasts for 2.3 months, from June 12 to August 21, with average wind speeds of more than 7.9 miles per hour. The windiest day of the year is July 28, with an average hourly wind speed of 9.4 miles per hour.
The calmer time of year lasts for 9.7 months, from August 21 to June 12. The calmest day of the year is September 25, with an average hourly wind speed of 6.5 miles per hour.
Average Wind Speed
The predominant average hourly wind direction in Ta’if varies throughout the year.
The wind is most often from the west for 1.1 months, from April 27 to May 31 and for 1.7 months, from June 28 to August 20, with a peak percentage of 53% on July 22. The wind is most often from the east for 2.3 months, from September 13 to November 23, with a peak percentage of 50% on October 10. The wind is most often from the south for 5.1 months, from November 23 to April 27, with a peak percentage of 38% on January 1.
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.
The brighter period of the year lasts for 3.5 months, from April 29 to August 13, with an average daily incident shortwave energy per square meter above 7.5 kWh. The brightest day of the year is June 24, with an average of 8.1 kWh.
The darker period of the year lasts for 2.7 months, from November 6 to January 28, with an average daily incident shortwave energy per square meter below 5.6 kWh. The darkest day of the year is December 16, with an average of 4.9 kWh.

This report illustrates the typical weather in Ta’if, 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 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Ta’if.
For each station, the records are corrected for the elevation difference between that station and Ta’if 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 Ta’if is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Ta’if and a given station.
The stations contributing to this reconstruction are: Taif Regional Airport (87%, 27 kilometers, northeast); Jeddah King Abdul Aziz International Airport (5%, 138 kilometers, west); and Al-Baha Domestic Airport (8%, 167 kilometers, southeast).
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.

We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands.
