Dallas, Texas Weather in August

August heat

Dallas in August is hot, with daytime highs around 37°C and warm nights near 25°C. Humidity and sudden showers can make afternoons feel sticky. The sun still shines for much of the day, but outdoor sightseeing is tiring at midday.

Plan indoor stops for the hottest hours. The Dallas Museum of Art and Perot Museum of Nature and Science are good choices, while the Dallas Arboretum is more comfortable earlier or later in the day. Save Klyde Warren Park and long walks around downtown for cooler hours. Families with young kids may find pool time easier than a full day outdoors.

Events and summer crowds

August brings the annual DFW Restaurant Week, when participating restaurants offer set menus and support local charities. Texas's back-to-school sales tax holiday also falls in August, drawing shoppers to malls and outlets. Dates vary, so check the calendar before you go.

This is summer, not Dallas's busiest sightseeing season. You'll often find fewer visitors and better hotel deals than in March, April or November. Still, indoor attractions can fill up on weekends, especially with local families escaping the heat.

Getting around

Rain falls on some August days, but it usually doesn't wash out a whole trip. Keep an indoor option handy when showers pass through, and don't plan a long exposed walk in the afternoon.

For a budget traveller, August can be a cheaper time to see Dallas, as long as you're happy to build your days around the heat. Use DART's downtown stops to reach the Arts District, then spend the hottest part of the day inside the Dallas Museum of Art or Crow Museum of Asian Art. Check DART routes before setting out; walking between nearby sights can feel much harder in the afternoon heat.
