Solar elevation and azimuth in the the fall of 2026. The black lines are lines of constant solar elevation (the angle of the sun above the horizon, in degrees). The background color fills indicate the azimuth (the compass bearing) of the sun. The lightly tinted areas at the boundaries of the cardinal compass points indicate the implied intermediate directions (northeast, southeast, southwest, and northwest).
MoonThe figure below presents a compact representation of key lunar data for the fall of 2026. 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. Moon Rise, Set & Phases in the Fall in Al Ḩasakah
The time in which the moon is above the horizon (light blue area), with new moons (dark gray lines) and full moons (blue lines) indicated. The shaded overlays indicate night and civil twilight.
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 Al Ḩasakah is essentially constant during the fall, remaining around 0% throughout. For reference, on August 6, the muggiest day of the year, there are muggy conditions 2% of the time, while on November 6, the least muggy day of the year, there are muggy conditions 0% 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 Al Ḩasakah is decreasing during the fall, decreasing from 8.1 miles per hour to 6.3 miles per hour over the course of the season. For reference, on June 30, the windiest day of the year, the daily average wind speed is 9.4 miles per hour, while on November 2, the calmest day of the year, the daily average wind speed is 6.1 miles per hour. The lowest daily average wind speed during the fall is 6.1 miles per hour on November 17. The wind direction in Al Ḩasakah during the fall is predominantly out of the west from September 1 to November 2 and the east from November 2 to November 30. Wind Direction in the Fall in Al Ḩasakah
northeastsouthwest
The percentage of hours in which the mean wind direction is from each of the four cardinal wind directions, excluding hours in which the mean wind speed is less than 1.0 mph. The lightly tinted areas at the boundaries are the percentage of hours spent in the implied intermediate directions (northeast, southeast, southwest, and northwest).
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). The growing season in Al Ḩasakah typically lasts for 9.7 months (294 days), from around February 26 to around December 17, rarely starting before January 29 or after March 20, and rarely ending before November 21 or after January 7. The fall in Al Ḩasakah is very likely fully within the growing season, with the chance that a given day is in the growing season rapidly decreasing from 100% to 80% over the course of the season.

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 Al Ḩasakah are very rapidly increasing during the fall, increasing by 1,732°F, from 4,511°F to 6,242°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 Al Ḩasakah is very rapidly decreasing during the fall, falling by 4.4 kWh, from 7.1 kWh to 2.7 kWh, over the course of the season. TopographyFor the purposes of this report, the geographical coordinates of Al Ḩasakah are 36.502 deg latitude, 40.748 deg longitude, and 1,001 ft elevation.

Within 10 miles contains only modest variations in elevation (814 feet). Within 50 miles contains significant variations in elevation (3,727 feet). The area within 2 miles of Al Ḩasakah is covered by bare soil (39%), cropland (34%), and sparse vegetation (21%), within 10 miles by cropland (45%) and bare soil (39%), and within 50 miles by cropland (46%) and bare soil (43%). Data SourcesThis report illustrates the typical weather in Al Ḩasakah, 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 are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Al Ḩasakah. For each station, the records are corrected for the elevation difference between that station and Al Ḩasakah 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 Al Ḩasakah is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Al Ḩasakah and a given station. The stations contributing to this reconstruction are:
 To get a sense of how much these sources agree with each other, you can view a comparison of Al Ḩasakah and the stations that contribute to our estimates of its temperature history and climate. Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data. 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.
