San Antonio is starting Friday partly sunny with a high near 93°F — if you’re planning anything outdoors in the Alamo City today, get moving early before the afternoon heat and humidity make the River Walk feel like a sauna.

Today’s Setup

South-southeast winds of 5 to 15 mph with gusts up to 25 mph are funneling Gulf moisture into the area all day. The National Weather Service notes that the dry air layer that normally keeps afternoon dewpoints in check isn’t doing its job as well today, so the heat will feel heavier than that 93°F number once the sun gets high. Tonight stays warm and mostly cloudy, with a low around 71°F and continued breezy conditions.

Best Window To Be Outside

Before 10 AM CT is your sweet spot. Joggers at Brackenridge Park, walkers along the Mission Reach, and anyone running weekend errands — morning is your window. After 11 AM CT, heat index values climb fast. Golfers at TPC San Antonio or Quarry Golf Club should wrap up by noon. If you’re spending extended time outdoors this weekend, UPF 50+ Fishing Shirts for $6.50 are worth grabbing for serious sun protection on the cheap.

Fire Risk — Don’t Overlook It

Gusty south winds and dry air ahead of next week’s rain make today a fire weather concern for San Antonio and the surrounding Hill Country. This is a smart time to review your home fire safety before peak summer: a smoke detector combo pack, a fire extinguisher home, and a fire blanket kitchen are basics worth having in place. If you live near brushy areas in Helotes, Bulverde, or anywhere along the Hill Country edge, check your gear now.

Spurs Potential Game 7: What To Know (Sunday, May 17)

The San Antonio Spurs could host the Minnesota Timberwolves in a potential West Conference Semifinals Game 7 this Sunday at Frost Bank Center. With highs near 93°F and heat indices possibly pushing toward 100–105°F, tailgating on the downtown streets before tipoff means hydration is non-negotiable. The arena is air-conditioned, so getting inside early is smart strategy. Snag a San Antonio Spurs jersey and Find tickets on StubHub if you’re still hunting for seats — this one could be electric.

Too Hot To Cook Tonight

Skip the oven and keep it cool: smoothie bowls, a cold Thai noodle salad, or a build-your-own wrap bar all hit perfectly on a 93°F evening. A high-powered blender handles smoothie bowls in under a minute. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
