Dubai 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 0% to 8%, 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 8% on March 15.

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.

Dubai experiences extreme seasonal variation in the perceived humidity.

The muggier period of the year lasts for 7.3 months, from April 13 to November 22, during which time the comfort level is muggy, oppressive, or miserable at least 23% of the time. The muggiest day of the year is July 19, with muggy conditions 86% of the time.

The least muggy day of the year is January 16, with muggy conditions 1% 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 Dubai experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 5.3 months, from December 30 to June 8, with average wind speeds of more than 4.4 miles per hour. The windiest day of the year is March 15, with an average hourly wind speed of 5.0 miles per hour.

The calmer time of year lasts for 6.7 months, from June 8 to December 30. The calmest day of the year is October 13, with an average hourly wind speed of 3.7 miles per hour.

Average Wind Speed

The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands.

The predominant average hourly wind direction in Dubai varies throughout the year.

The wind is most often from the east for 4.0 weeks, from August 4 to September 1, with a peak percentage of 32% on August 19. The wind is most often from the west for 11 months, from September 1 to August 4, with a peak percentage of 52% on January 1.

Dubai is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water.

The average water temperature experiences significant seasonal variation over the course of the year.

The time of year with warmer water lasts for 4.2 months, from June 12 to October 17, with an average temperature above 88°F. The day of the year with the warmest water is August 7, with an average temperature of 92°F.

The time of year with cooler water lasts for 3.3 months, from December 26 to April 6, with an average temperature below 75°F. The day of the year with the coolest water is February 9, with an average temperature of 71°F.

Solar Energy

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 2.6 months, from April 26 to July 13, with an average daily incident shortwave energy per square meter above 7.2 kWh. The brightest day of the year is June 4, with an average of 8.0 kWh.

Data Sources

This report illustrates the typical weather in Dubai, 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 Dubai.

For each station, the records are corrected for the elevation difference between that station and Dubai 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 Dubai is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Dubai and a given station.

The stations contributing to this reconstruction are: Dubai International Airport (77%, 26 kilometers, northeast); Abu Dhabi International Airport (13%, 88 kilometers, southwest); and Al Ain International Airport (10%, 100 kilometers, southeast).

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.
