Houston is heating up fast today, Saturday, July 18, with a high near 95°F, partly sunny skies, and heat index values climbing as high as 104°F, according to the National Weather Service — knock out yard work, dog walks, or a fishing trip before 10 AM CT, then plan on shade, AC, or the pool for the afternoon.
Today’s Setup
Building high pressure is parked over the region and will dominate our weather this weekend and into next week, per the National Weather Service Houston/Galveston office. Overnight lows only dip to around 78°F with a light south wind near 5 mph, and Saturday’s south wind stays light at 5 to 10 mph. Rain chances sit at just 7% today, so this is a dry, sunny, straight-up hot day across the Bayou City.
Best Window To Be Outside
Morning is your friend. Tee times at a course like Memorial Park or a bayou-side jog before 9 or 10 AM beat the worst of the heat index. Anglers working Lake Houston or the bayous should also aim for early light. Forecasters note a small chance of an isolated, short-lived shower or storm between 4-8 PM CT today near or just north of the metro — not enough to cancel plans, but worth a glance at the sky if you’re out that direction this afternoon.
Heat And Rain Risk
No severe weather outlook is in effect for Houston, and the Weather Prediction Center’s flood risk area today is focused on West Texas and the Southwest, not our metro. The real story here is heat: with index values near 104°F, drink water often, take breaks in shade, and keep an eye on kids and pets. Talc free body powder can help if you’re outside for extended stretches in this humidity.
Gameday And Weekend Events
The Houston Astros host the Baltimore Orioles at Daikin Park tonight (July 18) and again Sunday, then face the Miami Marlins on July 21. Tailgating outside the park will be sticky, so pack a rolling cooler with wheels and stay hydrated before first pitch. Get tickets on SeatGeek or find tickets on StubHub, and gear up in a Houston Astros jersey or Houston Astros fitted cap. Over in The Woodlands, Flatland Cavalry plays The Cynthia Woods Mitchell Pavilion tonight — an outdoor show, so expect a warm, humid evening near 78°F after sunset. Grab a Flatland Cavalry t-shirt or Flatland Cavalry hat and look for tickets on SeatGeek.
What To Bring
Light, breathable clothing and sun protection are musts. If fishing is on the agenda, stock up on catfish bait dip worms or a spinnerbait assortment — or check the Strike King Crankbaits deal from $6 at Bass Pro Shops before you head out. Browse more outdoor gear deals while you’re at it.
Tonight’s Dinner
With dry, sunny skies and a warm evening ahead, this is textbook grilling weather — burgers, steaks, or grilled chicken with corn on the cob. An instant-read meat thermometer and a grill brush and scraper set make cleanup and doneness a breeze. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Sunday turns even hotter with a high near 98°F, mostly sunny skies, and heat index values again up to 104°F. The National Weather Service expects the hot, mostly dry pattern to continue into next week, with highs in the 95-100°F range and rising humidity by midweek.
