Houston is starting Monday clear but sticky, with temperatures around 79 degrees before sunrise. The calm morning is a brief mercy: the city is headed for a high near 99, and the heat index could reach 104. A stray shower or thunderstorm may pop up after 4 p.m., but most of the day should stay sunny and dry.
According to the National Weather Service Houston/Galveston office, winds will stay light and generally southwest at 0 to 5 mph through the afternoon. Rain chances top out at 20%, so any storm is expected to be isolated rather than a citywide washout. The chance of rain should fade after 7 p.m. as skies clear again.
Heat And Ozone Add To The Outdoor Risk
Monday also carries an Ozone Action Day for the Houston-Galveston-Brazoria area through 7:30 p.m., according to the Texas Commission on Environmental Quality. People with breathing problems may want to limit strenuous outdoor activity during the afternoon, while everyone can help by avoiding drive-through idling, combining errands and conserving energy. No severe-weather watch or warning is in effect for Houston.
Hot Nights, Better Rain Chances Later
Tuesday should reach 97 degrees with heat index values up to 104, followed by a mostly clear night near 79. Wednesday and Thursday stay hot, with highs near 96 and 95; Thursday brings a better 40% chance of afternoon showers and thunderstorms. A few patches of fog could also return early Tuesday morning.
By Friday through Sunday, highs remain in the mid-90s, with overnight lows around 79. Rain chances rise to about 30% Friday and Sunday, while Saturday stays mostly sunny with only a slight storm chance. The overall pattern is clear enough: hot afternoons, warm nights and occasional summer storms trying to break up the routine.
Plan Outdoor Time Early
Light winds will do little to soften the heat, especially during the late afternoon. Plan strenuous outdoor work for early morning or evening, drink water regularly and take breaks in air conditioning when needed. If a storm forms, expect a brief interruption with lightning and showers rather than a long-duration rain event.
