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.

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.
