In Dallas, the temperature, humidity levels, and precipitation vary greatly from season to season. In general, winters are mild and summers are hot, though the humidity isn’t as unbearable as it is in other parts of Texas. July and August are the hottest months — it’s not uncommon to experience several 100-degree days in a row — while December, January, and February are the coldest months. Spring and fall are pleasant, although precipitation and strong storms are to be expected. Trying to decide which season is best for a visit? The beginning of fall tends to be a sweet spot in Dallas, since this is when the summer crowds die down, hotel prices are discounted, and temperatures are in the 70s and 80s degrees Fahrenheit.

Spring in Dallas

Spring in Dallas is the calm before the storm — the storm, in this case, being 100-degree summertime heat — so this can be a wonderful time to visit. Expect pleasantly warm temperatures (the highs range from the upper 80s to mid-60s), lush vegetation, colorful blooms in the parks, and a variety of seasonal festivals. Of course, a little rain (and occasionally hail) is to be expected, so travelers should be prepared.    

What to pack: Rain gear! This is the rainiest season in Dallas, so be sure to bring a rain jacket or umbrella and waterproof footwear on your trip.

Summer in Dallas

Ah, sweet summertime in the Big D — get ready for heat, heat, and more heat, especially if you’re visiting in July or August. In August, you can expect several days of 100-degree Fahrenheit heat (or higher) and little to no rain, and there are occasional heatwave warnings. Even though the heat can be stifling, Dallas is usually jam-packed with tourists in the summer because kids are out of school. Hotel prices are also more expensive than they are during fall and winter.   

What to pack: Your breeziest outfits, a sun hat, sunglasses, a reusable water bottle, and your strongest sunblock — Dallas summers are intense, so sun protection is an absolute necessity.
