San Antonio is heading into a mostly sunny Monday with a high near 94°F and a heat index near 100°F, so shift strenuous outdoor plans to the early morning or evening and keep water close all day.

Today’s Setup

The National Weather Service says a mid- to upper-level ridge stretching from northwestern Mexico into the northern Plains is keeping South Central Texas warm, with light south-southeast winds around 5 mph. A dissipating front draped over Central Texas could spark a few storms from the Southern Edwards Plateau down toward the I-35 Corridor this afternoon into evening, but rain chances sit at just 10% for San Antonio, so most neighborhoods stay dry. Tonight cools only to near 77°F under partly cloudy skies.

Best Window To Be Outside

Get outside before 10 AM CT if you can — that’s the best stretch for a walk along the River Walk, a jog through Brackenridge Park, or yard work before the sun takes over. Anyone near Lackland or Fort Sam Houston with midday errands should pace themselves; a hydration running vest makes a real difference on longer outdoor stretches. Once the heat index climbs toward 100°F between 1 and 6 PM CT, move activities indoors or wait for the evening.

Storm Chances & Heat Risk

Forecasters note an isolated storm or two could clip the northern edge of the metro late this afternoon, possibly with gusty winds, but confidence is low and most of San Antonio should stay rain-free. The bigger story is heat: expect this pattern — hot, dry, and near normal — to hold through Tuesday and strengthen further Wednesday as the ridge builds in.

What To Wear Or Bring

A cooling neck towel and a Stanley quencher tumbler filled with ice water are easy wins for anyone outdoors today. If you’re heading to a River Walk cooldown or a Hill Country day trip, a hard cooler 52 quart keeps drinks and snacks cold for hours, and the 2-Person Intex Floating Lounge with Cooler is a nice pickup at $24 on Amazon for floating a calmer stretch of water this week.

Joji Tonight, Dude Perfect This Week

Joji: SOLARIS plays Moody Center ATX tonight, and with the heat index still near 100°F at showtime, hydrate before you head out and look for tickets on SeatGeek — a Joji t-shirt makes an easy show-night pickup. Also on the calendar: Dude Perfect’s Squad Games Tour hits Moody Center ATX on Thursday, July 9. Grab tickets on StubHub and gear up with a Dude Perfect t-shirt, Dude Perfect hoodie, or Dude Perfect hat for the family.

Dinner Idea & Next Few Days

It’s too hot to cook tonight, so lean into a cold Thai noodle salad, a build-your-own wrap bar, or smoothie bowls — a high-powered blender makes quick work of it and an insulated tumbler 30oz keeps leftovers cold. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door. Looking ahead, the National Weather Service expects Tuesday near 95°F and Wednesday near 96°F, both sunny and essentially rain-free as the ridge strengthens — good news if you’re eyeing a mowing day (a cordless lawn mower beats fighting the heat with a gas engine) but one more reason to plan around the coolest hours. Check the San Antonio weather forecast for updates, and browse outdoor gear deals while this stretch of heat holds.
