Houston, today is shaping up to be a genuine scorcher: the National Weather Service is calling for sunny skies and a high near 100°F, with heat index values climbing as high as 106, and a Heat Advisory in effect from 11 AM to 8 PM CT. If you’ve got outdoor plans, do them early, hydrate constantly, and check on elderly neighbors, kids, and pets before anything else.

Today’s Setup

West winds stay light at 0 to 5 mph all day, which means little relief from air movement. Tonight only cools to a low around 80°F, still muggy with heat index values near 104 after sunset. According to the Houston weather forecast, Wednesday actually tops today, with highs near 104°F and heat index values possibly reaching 110-115 as the ridge center shifts over Oklahoma — the NWS Houston/Galveston office says another Heat Advisory, or even an Extreme Heat Watch, may be needed.

Best Window To Be Outside

Mornings before 10 AM are your best bet for a jog around Buffalo Bayou Park or a walk near Hermann Park before the advisory kicks in at 11 AM. If you’re heading to a pool day at Memorial Park or a bayou float, an Intex Floating Lounge with 2-Person Cooler, on sale for $24 on Amazon, is a smart grab this week. Save yard work, mowing, or grilling for after 8 PM once the advisory lifts and temperatures ease slightly.

Heat And Tropical Watch

Beyond the heat, NWS forecasters are watching Tropical Storm Bertha, expected to weaken as it approaches southeast Texas later this week. Confidence is still low, and rain/temperature forecasts for the back half of the week could shift — worth checking back for updates rather than locking in weekend plans just yet.

Gameday And Weekend Events

The Houston Astros host the Miami Marlins at Daikin Park on July 22 and July 23, with the Houston Dynamo FC facing D.C. United at Shell Energy Stadium on July 23 — expect hot, humid tailgating both days, so pack water over beer early. Grab a Houston Astros jersey or Houston Astros fitted cap before first pitch, or Find tickets on StubHub if you’re heading out. Concert season is heating up too: catch The Coral Reefer Band on July 24, Motionless In White on July 25, and the Fuerza Regida concert at Daikin Park on July 26. Get tickets on SeatGeek, and grab a Fuerza Regida t-shirt, Fuerza Regida hat, or Motionless In White t-shirt for the show.

What To Wear And Bring

Light, breathable clothing, sunscreen, and an insulated tumbler 30oz for ice water are non-negotiable today. For backyard evenings once the heat breaks, a TIKI Brand tabletop firepiece keeps the patio bug-free without adding to the heat.

With it this hot, skip the stove: a cold Thai noodle salad, a build-your-own wrap bar, or smoothie bowls whipped up in a high-powered blender are all easy, no-cook dinner options tonight. Need ingredients? You can order groceries on Amazon and have everything delivered to your door.

Next Few Days

Expect Wednesday to be the hottest day of the week near 104°F, followed by slightly lower but still steamy highs into Thursday near 98°F, with Bertha’s track adding uncertainty to the end of the week. Check our outdoor gear deals to stay prepared either way.
