The figure below shows you a compact characterization of the hourly average fall temperatures. The horizontal axis is the day, the vertical axis is the hour of the day, and the color is the average temperature for that hour and day. Chingueṭṭi, Mauritania (4,228 miles away) is the far-away foreign place with temperatures most similar to Abu Dhabi (view comparison). CloudsThe fall in Abu Dhabi experiences decreasing cloud cover, with the percentage of time that the sky is overcast or mostly cloudy decreasing from 29% to 21%. The lowest chance of overcast or mostly cloudy conditions is 8% on October 4. The clearest day of the fall is October 4, with clear, mostly clear, or partly cloudy conditions 92% of the time. For reference, on July 20, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 51%, while on October 4, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 92%. PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Abu Dhabi, the chance of a wet day over the course of the fall is gradually increasing, starting the season at 1% and ending it at 4%. For reference, the year's highest daily chance of a wet day is 7% on March 3, and its lowest chance is -0% on October 2. RainfallTo show variation within the season and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day. The average sliding 31-day rainfall during the fall in Abu Dhabi is essentially constant, remaining about 0.1 inches throughout, and rarely exceeding 1.0 inches or falling below -0.0 inches. The lowest average 31-day accumulation is 0.0 inches on October 17. SunOver the course of the fall in Abu Dhabi, the length of the day is rapidly decreasing. From the start to the end of the season, the length of the day decreases by 1 hour, 52 minutes, implying an average daily decrease of 1 minute, 15 seconds, and weekly decrease of 8 minutes, 44 seconds. The shortest day of the fall is November 30, with 10 hours, 45 minutes of daylight and the longest day is September 1, with 12 hours, 37 minutes of daylight. The earliest sunrise of the fall in Abu Dhabi is 6:03 AM on September 1 and the latest sunrise is 45 minutes later at 6:48 AM on November 30. The latest sunset is 6:40 PM on September 1 and the earliest sunset is 1 hour, 7 minutes earlier at 5:33 PM on November 29. Daylight saving time is not observed in Abu Dhabi during 2024. For reference, on June 20, the longest day of the year, the Sun rises at 5:34 AM and sets 13 hours, 39 minutes later, at 7:13 PM, while on December 21, the shortest day of the year, it rises at 7:02 AM and sets 10 hours, 37 minutes later, at 5:39 PM. The figure below presents a compact representation of the sun's elevation (the angle of the sun above the horizon) and azimuth (its compass bearing) for every hour of every day in the reporting period. The horizontal axis is the day of the year and the vertical axis is the hour of the day. For a given day and hour of that day, the background color indicates the azimuth of the sun at that moment. The black isolines are contours of constant solar elevation. MoonThe figure below presents a compact representation of key lunar data for the fall of 2024. The horizontal axis is the day, the vertical axis is the hour of the day, and the colored areas indicate when the moon is above the horizon. The vertical gray bars (new Moons) and blue bars (full Moons) indicate key Moon phases. The label associated with each bar indicates the date and time that the phase is obtained, and the companion time labels indicate the rise and set times of the Moon for the nearest time interval in which the moon is above the horizon. HumidityWe 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 chance that a given day will be muggy in Abu Dhabi is very rapidly decreasing during the fall, falling from 90% to 29% over the course of the season. For reference, on July 29, the muggiest day of the year, there are muggy conditions 91% of the time, while on January 16, the least muggy day of the year, there are muggy conditions 4% of the time. WindThis 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 Abu Dhabi is gradually increasing during the fall, increasing from 7.7 miles per hour to 8.6 miles per hour over the course of the season. For reference, on February 18, the windiest day of the year, the daily average wind speed is 10.1 miles per hour, while on September 17, the calmest day of the year, the daily average wind speed is 7.5 miles per hour. The lowest daily average wind speed during the fall is 7.5 miles per hour on September 17. The hourly average wind direction in Abu Dhabi throughout the fall is predominantly from the north, with a peak proportion of 52% on November 6. Water TemperatureAbu Dhabi 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 surface water temperature in Abu Dhabi is very rapidly decreasing during the fall, falling by 14°F, from 92°F to 78°F, over the course of the season. Growing SeasonDefinitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere). Temperatures in Abu Dhabi are sufficiently warm year round that it is not entirely meaningful to discuss the growing season in these terms. We nevertheless include the chart below as an illustration of the distribution of temperatures experienced throughout the year. Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F. The average accumulated growing degree days in Abu Dhabi are very rapidly increasing during the fall, increasing by 2,884°F, from 6,988°F to 9,871°F, over the course of the season. Solar EnergyThis 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 in Abu Dhabi is very rapidly decreasing during the fall, falling by 2.5 kWh, from 6.9 kWh to 4.4 kWh, over the course of the season.

Data SourcesThis report illustrates the typical weather in Abu Dhabi, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Temperature and Dew PointThere is only a single weather station, Abu Dhabi Bateen Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Abu Dhabi. At a distance of 10 kilometers from Abu Dhabi, 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 Abu Dhabi 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 DataAll data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition , 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.

Weather data is prone to errors, outages, and other defects. We assume no responsibility for any decisions made on the basis of the content presented on this site. 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. We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
