Visiting Houston in August

August feels

Houston in August is seriously hot and sticky. Days reach 36°C, and even nights stay warm at around 24°C. Humidity is high, and rain falls on about 14 days, often in heavy showers. July is slightly hotter, but August still isn't an easy month for long walks.

Plan outdoor sightseeing for a short stretch, then cool off indoors. The Museum of Fine Arts, Houston, and the Houston Museum of Natural Science both make good midday stops. Buffalo Bayou Park is better saved for a cooler part of the day.

Make the most of indoors

If you hate crowds, August can suit you: it's summer low season, and you'll often find better hotel deals than in February, March or November. Family attractions may feel quieter as school resumes later in the month, though dates vary.

Travelling with kids? The Downtown Aquarium gives you an air-conditioned break between outings. For the Museum District, take the METRORail Red Line from downtown instead of walking between sights in the heat.

Events and trade-offs

Houston Restaurant Weeks runs in August, with participating restaurants offering set menus and raising money for the Houston Food Bank. It's a nice reason to try local favourites, from Gulf seafood to Tex-Mex. Check which restaurants are taking part before choosing where to eat.

Rain can interrupt outdoor plans, so keep a museum or meal in reserve. You'll get more comfortable sightseeing in spring or autumn, but August can mean fewer visitors and lower prices. If you're set on a park visit, Hermann Park is close to the Museum District, making it easy to switch indoors when the heat or a shower catches up with you.
