Dallas-Fort Worth is in for a sunny, seasonably hot Sunday with a high near 99°F and heat index values as high as 103°F, so the National Weather Service’s advice holds: knock out your outdoor plans early and let the afternoon be an indoor, AC-cooled affair.
Today’s Setup
Skies stay sunny all day with a light south wind around 5 to 10 mph. Rain chances are basically nonexistent at just 3%, and forecasters note that persistent deep boundary layer mixing is keeping afternoon dewpoints in the low-to-mid 60s — that’s actually helping keep heat index values just under advisory criteria. Overnight lows only dip to around 80°F, so there’s little relief once the sun goes down.
Best Window To Be Outside
If you’re hitting the trails at White Rock Lake, walking the Katy Trail, or teeing off at one of Cowtown’s public courses, aim for before 10 AM CT. Golf weather is genuinely nice early — calm wind, full sun, low humidity — but heat builds fast, and by early afternoon the heat index climbs toward 103°F. A golf towel microfiber and a UV protection sun hat are smart additions to the bag this week.
Rain, Wind, Fire, Or Heat Risk
No severe weather is expected locally today — there’s no Storm Prediction Center outlook covering North Texas, and the flood risk from the Weather Prediction Center is focused on the Upper Midwest, not DFW. The bigger story is dryness: the Area Forecast Discussion flags that grass fire activity threat increases by the middle and latter part of next week as ridging strengthens and keeps things hot and dry. It’s worth having a garden hose 100ft ready near dry landscaping and brush now, before conditions worsen.
What To Wear Or Bring
Light, breathable clothing, sunscreen, and water are non-negotiable through Monday, when highs push to 100°F. For sun protection on the go, check out the UPF 50+ Sun Hoodie deal — handy for anyone fishing, boating, or just spending time outside this week. Browse more outdoor gear deals while you’re at it.
This Week’s Games & Concerts
The Guess Who play Dickies Arena tonight (Aug. 9), a good indoor option to dodge the heat. CORTIS brings its 2026 tour to The Pavilion at Toyota Music Factory in Irving on Aug. 11 — Get tickets on SeatGeek. Then American Airlines Center gets busy with the Don Toliver concert on Aug. 13 (grab a Don Toliver t-shirt or Don Toliver hoodie) and the Megan Moroney show on Aug. 14 — a Megan Moroney t-shirt makes a great souvenir, and Find tickets on StubHub if you still need seats.
Tonight’s Dinner
With clear skies and calm wind, tonight is genuinely great grilling weather — burgers, steaks, or grilled chicken with corn on the cob all work well. An instant-read meat thermometer and grill brush and scraper set will make cleanup and doneness a lot easier. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Monday holds at a sunny, dry 100°F with south wind gusting to 20 mph. The ridge parked over the Southern Plains keeps highs in the 99-103°F range through the week — hot but, per the Fort Worth forecast office, not oppressive for August. Watch for that fire danger to build by midweek as dry conditions persist.
