Houston woke up to a muggy, partly cloudy start on Tuesday, April 28, 2026, with temperatures already in the mid-70s and dewpoints parked in the low 70s. The city is in for a summer-style preview through the day, with highs near 90°F and thick humidity making it feel even hotter. South winds will ramp up this afternoon, so expect gusts that could turn simple yard work into a wind-swept chore.
Afternoon Heat And Gusty South Winds
Southerly winds of 10 to 15 mph are expected Tuesday, with afternoon gusts that could reach 25 mph, strong enough to jostle patio umbrellas and send loose items skittering across driveways. Temperatures should top out near 90°F before slipping a few degrees into the evening. With the heat and humidity teaming up, it will feel hotter than the thermometer suggests across much of the city. If you are spending time outside, bring water, look for shade and make sure kids and pets get regular breaks.
Wednesday Through Friday: Storms And Rising Rain Chances
A cold front and a series of upper-level disturbances will boost rain chances by Wednesday, April 29, 2026, bringing a growing threat of showers and thunderstorms in the afternoon and evening. According to the National Weather Service Houston/Galveston, there is a marginal risk for severe storms along with an elevated potential for locally heavy downpours and flash flooding as the week wears on. Showers and thunderstorms look most likely on Friday, May 1, when widespread rain and storms are possible ahead of the front.
Weekend Cool-Down And Marine Notes
If the front arrives on schedule late Friday night into Saturday, it should usher in a cooler, breezier weekend on Saturday, May 2, with highs dropping into the low 70s and overnight lows sinking into the 50s. On the water, mariners should plan for elevated water levels of about 2.5 to 3.0 feet above MLLW at each high tide cycle through early next week, and gusty winds late in the week could create small craft concerns.

Plan outdoor activities with flexibility and keep an umbrella handy from Wednesday through Friday in case showers build quickly. Check hourly forecasts before hitting the road and stay tuned to local alerts if storms fire up.
