Houston is looking at a mostly sunny, dangerously hot Tuesday with a high near 98°F and a heat index climbing to 107°F, so the National Weather Service has a Heat Advisory in effect this afternoon — plan strenuous outdoor time for early morning or after sunset. Check the full Houston weather forecast before you head out.
Today’s Setup
Southeast Texas is stuck under a strong mid-level high — what forecasters at NWS Houston/Galveston are calling a heat dome — parked over northern Texas through at least Thursday. That upper-level ridge is compressing and warming air as it sinks toward the surface, which is why afternoon highs keep landing in the upper 90s to 100°F with heat index values in the 106-112°F range. Winds stay light out of the south at 5 to 10 mph, and tonight only cools to near 79°F with heat index values still around 105°F — no real relief after dark.
Best Window To Be Outside
NWS forecasters note patchy fog is possible during the early-to-mid morning hours over the next several days, so give it a little extra caution on your commute along the Gulf Freeway or through the Ship Channel area before sunrise. Once that clears, your best window for a run along Buffalo Bayou or a walk through Discovery Green is before 9 AM CT. By midday, pavement and turf get brutal — hold off on mowing, yard work, or anything strenuous until evening.
Heat & Fire Risk
With temperatures this extreme and grass drying out fast, fire risk climbs even without a formal red flag warning. Keep a fire extinguisher home within reach if you’re grilling or running equipment outdoors, and it’s smart to have a go bag emergency evacuation kit and a 5-gallon water storage container on hand — good practice for any Gulf Coast household given our hurricane-season backdrop.
What To Wear Or Bring
Lean on a UV protection sun hat and light, breathable layers if you’re outside midday. Deal alert: a UPF 50+ Sun Hoodie is down to $5 right now, a smart grab before your next fishing trip or bayou outing. Pair it with men’s sport sandals for anything involving water, and don’t skip sunscreen — heat index near 107°F means burns come fast.
Game Day & Weekend Events
The Houston Astros host the Texas Rangers at Daikin Park on August 1 — it’s an indoor stadium, so the heat won’t touch the game, making it an easy call for families dodging the outdoor swelter. Find tickets on StubHub and grab Official team gear on Fanatics before first pitch. Music fans have two options Friday, July 31: The Fray and Dashboard Confessional bring the Summer of Light Tour to 713 Music Hall, while The Pussycat Dolls play the outdoor Cynthia Woods Mitchell Pavilion — with heat index still near 100°F at showtime, that outdoor crowd should hydrate hard. Get tickets on SeatGeek for either show.
Dinner Tonight
It’s too hot to turn on the oven. A cold Thai noodle salad or a build-your-own wrap bar keeps the kitchen cool, and smoothie bowls made in a high-powered blender are an easy, no-cook dinner win. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Wednesday repeats the pattern — high near 98°F, heat index near 106°F — and Thursday pushes to 100°F as the heat dome holds firm. Houston, Hobby Airport, and College Station have only hit 100°F once so far this year; NWS forecasters say we could add a couple more days to that list this week.
