San Antonio is waking up to a hot, humid Monday with highs near 94°F and heat index values climbing to around 102°F across the metro area, including neighborhoods along the River Walk and near the I-35 Corridor.

This early-season heat is no joke, folks. The National Weather Service is urging all of us to take precautions to avoid heat illness. Wear light-colored, loose-fitting clothes, take breaks if you’re working outdoors, and stay hydrated throughout the day. The humidity will make it feel worse than the actual temperature, so don’t be fooled by that 94-degree reading on your thermometer.

Today’s Activity Breakdown:

If you’ve got outdoor plans around the Hill Country or near Lackland Air Force Base, get them done early—before 11 AM CT is your sweet spot. Golfers heading to local courses should grab a golf hat visor to shield from the intense sun; those adidas Samba Spikeless Golf Shoes Half Off at $42 are a solid deal if you’re looking to upgrade your game without the heat stress. Fishing enthusiasts have a decent window this morning on the San Antonio River or nearby lakes—grab a fishing hat with neck flap to stay protected, and consider the Plano Double-Sided Tackle Box Under $14 if you need to organize your gear.

The afternoon is brutal. Stay inside, hit the air conditioning, and save the grilling for sunset.

Tonight & Tuesday:

Monday night will stay warm and muggy with lows around 75°F. Tuesday is virtually a repeat—another hot, uncomfortable day with highs near 95°F and heat indices reaching 105°F. This pattern doesn’t break until Wednesday when a cold front finally moves in from North Texas.

Spurs Playoff Action Tonight:

If you’re heading to the Frost Bank Center for the Spurs Rd 1 Game 5 against the Trail Blazers on Tuesday, April 28th, you’ll be in full air conditioning—thankfully! The indoor venue will be a welcome escape from the heat. Grab Official team gear on Fanatics to show your support, and if you need tickets, check out Get tickets on SeatGeek or Find tickets on StubHub for the best deals.

Grilling & Dinner Plans:

Wait until sunset (around 8:30 PM CT) to fire up the grill for burgers, steaks, or grilled chicken with corn on the cob. The evening temps will be slightly more bearable, though still warm. Make sure you have an instant-read meat thermometer and grill brush and scraper set on hand to nail your cook. Need ingredients? You can order groceries on Amazon Fresh and have everything for tonight’s dinner delivered to your door.

Looking Ahead:

Rain chances return Wednesday and stick around through Friday as that cold front pushes through. Relief is coming, but for now, embrace the heat, stay smart, and keep your water bottle close. Check the San Antonio weather forecast for updates as the week unfolds.
