Houston is starting Sunday, May 31 under mostly cloudy skies with a high near 93°F — patchy fog near the bayous is possible between 7 and 8 AM CT, then it clears to partly sunny and full-on Houston summer heat for the rest of the day.
Today’s Setup
The National Weather Service says a weak ridge of high pressure over the Southern Plains is keeping us dry this weekend, but it’s just weak enough to draw Gulf moisture northward — which explains the hazy mornings and mostly cloudy nights. Southeast winds of 5 to 10 mph bring a faint sea breeze, though with overnight lows stuck around 75–76°F, the humidity never fully backs off. Isolated spots across the metro could nudge toward the mid-90s, so don’t let the “partly sunny” label fool you.
Best Time To Be Outside
Your prime outdoor window is early morning. Get your walk along Buffalo Bayou Hike & Bike Trail done, knock out the lawn, or tee off at Memorial Park Golf Course before 11 AM CT. Once the sun is fully up, the heat index will make extended outdoor work uncomfortable fast.
Tonight’s Houston Astros vs. Milwaukee Brewers game at Daikin Park should be the best part of the day — temps easing into the upper 80s by first pitch and mostly dry skies overhead. Bring a Stanley tumbler 40oz to stay hydrated through the late innings, and rep the home team in a Houston Astros jersey or Houston Astros fitted cap.
Heat and Rain Risk
No heat advisory is in place for today, but the National Weather Service notes heat index values will climb toward 101°F by Monday afternoon. Today’s risk is straightforward: 93°F plus Gulf humidity. Stay hydrated, limit midday sun exposure, and check on elderly neighbors and pets.
Rain-wise, Sunday is essentially dry — just a 3% chance. The first real storm threat arrives Monday, when a slight chance of showers and thunderstorms develops after 1 PM CT, mainly along the coast near Galveston along the afternoon seabreeze. A weak boundary from the northeast may push activity further inland Tuesday, but NWS forecasters caution these boundaries frequently stall before reaching Southeast Texas. Daily slight chances continue through the week, with moisture building toward Thursday and Friday.
Events and Gameday Conditions
Tonight, Carín León performs at Toyota Center — a great indoor show to duck the evening humidity. Get tickets on SeatGeek before they’re gone.
Looking ahead: Yellowcard brings their Up Up Down Down Tour to 713 Music Hall on June 4. Snag a Yellowcard t-shirt and Find tickets on StubHub for a fun Thursday night out. The Astros also host the Pittsburgh Pirates on June 3 at Daikin Park — check the Houston weather forecast as that date approaches, since Monday’s storm pattern could linger.
Grill Tonight and Next Few Days
Low wind, warm temps, and a dry evening make Sunday the best grilling night of the week. Fire up burgers, steaks, or grilled chicken with corn on the cob — classic Houston summer fare. Make sure your instant-read meat thermometer and grill brush and scraper set are close at hand before you light the burners. Need to stock up? You can order groceries on Amazon and have everything for tonight’s dinner delivered straight to your door.
Outlook: Upper 80s to low 90s hold through at least midweek with daily afternoon storm chances. Moisture increases toward the end of the week, bumping up coverage Thursday into Friday. For updated outdoor gear deals heading into summer storm season, we’ve got you covered.
