The latest sunset is 8:39 PM on July 1 and the earliest sunset is 13 minutes earlier at 8:26 PM on July 31. Daylight saving time is observed at Dallas Love Field during 2024, but it neither starts nor ends during July, so the entire month is in standard time. For reference, on June 20, the longest day of the year, the Sun rises at 6:19 AM and sets 14 hours, 19 minutes later, at 8:38 PM, while on December 21, the shortest day of the year, it rises at 7:26 AM and sets 9 hours, 59 minutes later, at 5:25 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 July 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 at Dallas Love Field is gradually decreasing during July, falling from 81% to 78% over the course of the month. The highest chance of a muggy day during July is 81% on July 2. For reference, on July 2, the muggiest day of the year, there are muggy conditions 81% of the time, while on January 21, 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 at Dallas Love Field is gradually decreasing during July, decreasing from 9.1 miles per hour to 8.4 miles per hour over the course of the month. For reference, on April 1, the windiest day of the year, the daily average wind speed is 11.9 miles per hour, while on August 22, the calmest day of the year, the daily average wind speed is 8.1 miles per hour. The hourly average wind direction at Dallas Love Field throughout July is predominantly from the south, with a peak proportion of 70% on July 5. 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 at Dallas Love Field typically lasts for 9.2 months (279 days), from around February 26 to around December 1, rarely starting before January 21 or after March 21, and rarely ending before November 7 or after December 22. The month of July at Dallas Love Field is reliably fully within the growing 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 at Dallas Love Field are very rapidly increasing during July, increasing by 990°F, from 2,783°F to 3,773°F, over the course of the month. 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 at Dallas Love Field is essentially constant during July, remaining within 0.1 kWh of 6.8 kWh throughout. The highest average daily incident shortwave solar energy during July is 7.0 kWh on July 3.

Data SourcesThis report illustrates the typical weather at Dallas Love Field, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Temperature and Dew PointDallas Love Field has a weather station that reported reliably enough during the analysis period that we have included it in our network. When available, historical temperature and dew point measurements are taken directly from this weather station. These records are obtained from NOAA's Integrated Surface Hourly data set, falling back on ICAO METAR records as required. In the case of missing or erroneous measurements from this station, we fall back on records from nearby stations, adjusted according to typical seasonal and diurnal intra-station differences. For a given day of the year and hour of the day, the fallback station is selected to minimize the prediction error over the years for which there are measurements for both stations. The stations on which we may fall back include but are not limited to Addison Airport, Dallas United States Naval Air Station, Dallas/Fort Worth International Airport, Dallas Executive Airport, Grand Prairie Municipal Airport, Arlington Municipal Airport, Lancaster Regional Airport, and Mesquite Metro Airport. 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.
