Houston is starting Saturday with a high near 94°F under mostly sunny skies — but with a heat index reaching up to 103°F by afternoon, the National Weather Service is urging everyone to pace themselves outdoors. Get your plans locked in early, because the Houston weather forecast takes a sharp turn by Sunday.
Today’s Setup
Subtropical ridging is keeping the heat locked over Southeast Texas through today. The NWS expects a slight chance of showers and thunderstorms after 11 AM CT, but forecasters note that subsidence will keep most storms light and brief. The real story is the humidity: afternoon dewpoints in the 70s push WBGT heat stress to high, with isolated pockets of extreme heat stress possible during peak afternoon hours. Sensitive groups and anyone not yet acclimated to Houston summers are especially at risk.
Best Window To Be Outside
Get moving before 10 AM CT — a morning run through Memorial Park or a walk along Buffalo Bayou is your best bet before the heat index climbs. Today’s conditions are solid for fishing and golf if you’re out early. Bring water, wear breathable fabrics, and keep some talc free body powder on hand for the relentless Gulf Coast humidity. For the kids, a kiddie splash pad in the backyard beats standing in the sun at a splash park during peak heat.
Heat & Coastal Risk
Today’s heat index tops out near 103°F — and Sunday pushes that to 107°F. The NWS is issuing a High Risk of Rip Currents at Galveston Island and area beaches this weekend. If you’re heading to the coast, swim near a lifeguard and stay clear of jetties and piers, where rip currents are most dangerous. Minor coastal flooding is also possible at high tide Sunday.
Events: Tonight and the Week Ahead
Tonight is a great night for live music: catch the Charlie Puth: Whatever’s Clever! World Tour at 713 Music Hall, or head to The Cynthia Woods Mitchell Pavilion for Taylorville - A Tribute to Taylor Swift. It’ll be warm and muggy heading into showtime — dress light and hydrate. Get tickets on SeatGeek if you still need them.
Looking ahead: the Houston Astros host the Detroit Tigers at Daikin Park on Tuesday, June 16 — Sunday’s storms should be well clear by then. Gear up with a Houston Astros jersey or Houston Astros fitted cap before you head to the ballpark. On June 18, Kali Uchis brings the For The Girls Tour with special guest Mariah The Scientist to The Cynthia Woods Mitchell Pavilion, and Khalid plays his It’s Always Summer Somewhere Tour at 713 Music Hall. Find tickets on StubHub and grab a Kali Uchis t-shirt for the show.
Grill Tonight While You Can
Saturday evening is your grilling window before Sunday’s storms move in. Fire up the propane gas grill for burgers, steaks, or grilled chicken with corn on the cob. Keep an instant-read meat thermometer on hand to nail every internal temp, and use a grill brush and scraper set for a quick cleanup after. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Sunday is the bigger story: 60% chance of storms, heat index near 107°F, and the NWS warns of flash flooding risk extending through late Tuesday. Houston’s bayous fill fast — take low-water crossings seriously Sunday night through Monday.
