![]() Especially hot and dry summers occurred in 1980, 2011, 20. Days with temperatures exceeding 100 ☏ (38 ☌) happen at least several times during the summer every year. In July and August, the average high temperature is near 96 ☏ (36 ☌), while the average nighttime low temperature is around 77 ☏ (25 ☌). ![]() The city's all-time recorded high temperature is 113 ☏ (45 ☌) during the Heat Wave of 1980. During the summer, the greater Dallas area receives warm to hot, dry airflow from Southwestern desert areas to the west and southwest, as well as hot, humid air from the Gulf of Mexico. Heat waves can be severe and prolonged, usually coinciding with severe drought. Wetter (generally less hot) periods occur in a minority of years. Summers are very hot and variably humid, with extended periods of hot, dry weather common in many summers. Dallas experiences mild winters and hot summers. It has a humid subtropical climate ( Köppen climate classification: Cfa) that is characteristic of the southern plains of the United States. temperatures in ☌ĭallas is located in North Texas, built along the Trinity River.

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. 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 draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. We assume no responsibility for any decisions made on the basis of the content presented on this site. Weather data is prone to errors, outages, and other defects. The information on this site is provided as is, without any assurances as to its accuracy or suitability for any purpose. Time zones for airports and weather stations are provided by. Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database. Land Use data comes from the Global Land Cover SHARE database, published by the Food and Agriculture Organization of the United Nations.Įlevation data comes from the Shuttle Radar Topography Mission (SRTM), published by NASA's Jet Propulsion Laboratory. 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. Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data.Īll 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.Īll other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis.
