Houston, Texas Weather in May

Warm, humid days

May feels like summer arriving early. Afternoons reach 31°C, and humidity can make walking around Downtown feel sticky. Evenings are milder, with lows around 20°C, so dinner outside can still be pleasant.

Rain falls on about 11 days, often in heavy showers. Keep flexible plans: spend a wet afternoon at the Houston Museum of Natural Science, then wander Hermann Park when the skies clear. Buffalo Bayou Park is lovely for a walk, but muddy paths and sudden downpours can spoil a longer outing. The beach is a drive away, and May's unsettled weather makes it a less reliable day trip.

May events and crowds

Cinco de Mayo brings Mexican food and celebrations around Houston, especially in the East End. Memorial Day weekend also marks the start of summer travel for many families, so popular attractions can feel busier then.

If you hate crowds, visit the Museum District on a weekday rather than during the holiday weekend. May isn't the main rodeo rush; the Houston Livestock Show and Rodeo takes place earlier in the year. Prices vary, but you may find less pressure than during that major event or peak summer holidays.

Make the most of a shower

Houston's METRORail Red Line links Downtown with the Museum District and the Texas Medical Center. It's handy when rain makes a long walk unpleasant, though you'll still need to cross between stops and sights.

Travelling with kids? Pair Hermann Park's playground and Japanese Garden with the nearby museums, so a sudden shower doesn't derail the day. Try crawfish while they're in season at a Houston seafood spot; messy, spicy boils are a local spring favourite. Check the restaurant's serving dates, since the season can vary.
