San Antonio is waking up to another sunny, scorching Monday with a high near 98°F and heat index values climbing to 103, so if you’ve got errands, yard work, or a River Walk stroll planned, front-load it for early morning or push it to after sunset.
Today’s Setup
The National Weather Service says a strong subtropical ridge is parked over the region, and the Gulf surface high is nudging slightly west today, which actually brings a wind direction more conducive to heat. Winds stay light out of the SSE at 5 to 10 mph, skies stay sunny with maybe a wisp of cirrus, and there’s no rain in the forecast. Tonight stays mostly clear with a low around 76 and heat index values still touching 103 — it just won’t cool off much.
Best Window To Be Outside
Morning before 10 AM CT is your best bet for the Pearl, Brackenridge Park, or a lap of the River Walk. By midday, pavement and direct sun push the heat index into the low 100s, and forecasters note today and Tuesday could briefly brush Heat Advisory criteria in spots, though confidence in an actual advisory is low for now. Tuesday runs just as hot, near 99°F with heat index near 105.
Heat And Fire Risk
With no rain and steadily warming air expected all week, NWS forecasters flag increasing heat risk — highs are trending toward the 100-105°F range by late week with heat indices potentially reaching 105-110, which could prompt actual heat products later on. The dry stretch also means elevated fire risk around Hill Country brush and grass; keep a fire extinguisher home handy and a smoke detector combo pack fresh with batteries. If any burning or grilling is happening near dry grass, an N95 respirator mask smoke is worth having on hand in case smoke drifts your way. On the flip side, San Antonio’s usual flash-flood-alley worries are off the table this week — no rain means no flooding concern for the River Walk or low-water crossings.
What To Wear Or Bring
Think breathable, light-colored clothing, men’s sport sandals or a women’s swimsuit if you’re near a pool, and don’t skip talc free body powder for chafing relief in this humidity. A lip balm SPF moisturizing stick protects lips from sun and dry air. If you’re near Lackland or Fort Sam Houston and outdoors for training or work, hydration breaks matter more than usual.
Around Town
Tuesday (July 28) brings the Lionel Richie and Earth, Wind & Fire concert at Frost Bank Center — tickets on SeatGeek if you’re going, and expect a hot pre-show wait near 99°F, so hydrate before you’re in line. Hamilton (Touring) also opens at the Majestic Theatre San Antonio that same night; the venue’s indoor, but the walk in from parking will feel like triple digits. If you need sun gear before then, the UPF 50+ sun hoodie deal is worth a look.
Tonight’s Dinner
Too hot to fire up the stove tonight — a cold Thai noodle salad or smoothie bowls made in a high-powered blender hit the spot. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Hot and dry holds through the week as the ridge sticks around, with highs widening into the 100-105°F range and heat indices possibly reaching 105-110 by mid-to-late week. NWS forecasters note a possible pattern shift may bring some change by Saturday, so keep an eye on updates as the weekend approaches.
