San Antonio is waking up to mostly cloudy skies and a high near 94°F today, but here’s the real story: the heat index will feel closer to 105°F, so it’s going to feel like the Hill Country in July.
The National Weather Service is tracking elevated humidity that’ll stick around through tonight, making that 73°F overnight low feel more like 102°F. Winds are light—just 5 to 10 mph from the south-southeast with gusts up to 20 mph—so don’t expect much relief from a breeze. There’s a slim 5% chance of rain today, so the River Walk area and downtown won’t see much activity, but folks around the Southern Edwards Plateau (think Terrell County direction) should keep an eye out for an isolated storm overnight that could briefly turn strong before fading.
If you’re heading to the Spurs Rd 1 Game 5 against the Trail Blazers at the Frost Bank Center tonight, you’re in luck—it’s indoors with full AC. Game time will be comfortable, and you can grab Official team gear on Fanatics to show your support. Tailgating conditions beforehand will be hot and humid, so bring plenty of water and find shade near the parking areas.
Here’s what to do today:
- Skip the lawn mower. Morning clouds might linger into early afternoon, and the heat index makes midday yard work dangerous. If you must cut grass, do it early (before 10 AM CT) or wait until evening after 6 PM CT when temps drop.
- Fishing at Brackenridge Park or local Hill Country spots? Bring a hydration backpack and take frequent breaks. The heat is no joke.
- Grilling plans? Save them for Thursday or Friday when temps dip to the upper 80s. Today’s heat makes standing over a grill miserable.
Mid-week change is coming. By Wednesday afternoon, a pair of cold fronts will push in from the northeast, bringing a slight chance of showers and thunderstorms (20% chance after 1 PM CT Wednesday). The National Weather Service notes the strongest rainfall signal occurs Friday, with locally heavy rain possible as organized storms develop. While San Antonio itself sits outside the excessive rainfall zone (that’s more Arklatex), we could still see some decent moisture. This is great news for cooling things down—highs Wednesday drop to 89°F.
Given the dangerous heat today, skip the kitchen entirely. Try a cold Thai noodle salad, build-your-own wrap bar, or smoothie bowls—a high-powered blender makes quick work of frozen fruit and yogurt. You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Looking ahead: The system clears out by the weekend, drying things up and keeping temps pleasant (low 80s Saturday–Sunday). By early next week, we’re back to warm and sunny conditions.
Stay hydrated, check on elderly neighbors, and keep an eye on the radar Wednesday into Friday. This is classic San Antonio spring weather—hot, humid, then a quick system that reminds us why we love Hill Country thunderstorms.
