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 Al Muwayh, 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 Al Muwayh experiences significant seasonal variation over the course of the year.
The windier part of the year lasts for 1.7 months, from June 22 to August 14, with average wind speeds of more than 9.6 miles per hour. The windiest day of the year is July 17, with an average hourly wind speed of 11.3 miles per hour.
The calmer time of year lasts for 10 months, from August 14 to June 22. The calmest day of the year is May 24, with an average hourly wind speed of 7.9 miles per hour.
Average Wind Speed
The predominant average hourly wind direction in Al Muwayh 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.
The brighter period of the year lasts for 3.5 months, from May 7 to August 24, with an average daily incident shortwave energy per square meter above 7.6 kWh. The brightest day of the year is June 21, with an average of 8.3 kWh.
The darker period of the year lasts for 2.7 months, from November 9 to January 30, with an average daily incident shortwave energy per square meter below 5.4 kWh. The darkest day of the year is December 22, with an average of 4.7 kWh.

Temperature and Dew Point
There is only a single weather station, Taif Regional Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Al Muwayh.
At a distance of 165 kilometers from Al Muwayh, further than our threshold of 150 kilometers, this station is deemed insufficiently nearby to be relied upon as our primary source for temperature and dew point records. Consequently, the station records are blended with interpolated values from NASA's MERRA-2 satellite-era reanalysis , and both are corrected for elevation differences according to the International Standard Atmosphere .
The weight assigned to the MERRA-2 value depends on the distance from Al Muwayh to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 23%, making the weight assigned to the weather station 77%.
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.

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.
