Abha 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 7%, with an average value of 3%.

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 7% on August 6.

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 of the year. Abha experiences some seasonal variation in monthly rainfall.

The rainy period of the year lasts for 1.6 months, from March 21 to May 8, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around April 14, with an average total accumulation of 0.6 inches.

The rainless period of the year lasts for 10 months, from May 8 to March 21. The least rain falls around September 27, with an average total accumulation of 0.1 inches.

Daylight saving time (DST) is not observed in Abha during 2017.

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 Abha, 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 3% of 3% 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 Abha experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 3.9 months, from January 2 to April 30, with average wind speeds of more than 3.8 miles per hour. The windiest day of the year is March 14, with an average hourly wind speed of 4.5 miles per hour.

The calmer time of year lasts for 8.1 months, from April 30 to January 2. The calmest day of the year is August 28, with an average hourly wind speed of 3.1 miles per hour.

Temperature and Dew Point

There is only a single weather station, Abha Regional Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Abha.

At a distance of 16 kilometers from Abha, 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 Abha 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.
