San Antonio is in for a partly sunny, seasonably hot Sunday with a high near 95°F and heat index values climbing to 101, so if you’re heading outside for River Walk strolls or Fiesta-season errands, plan around the hottest hours. Light south-southeast wind of just 0 to 5 mph means little relief, and the National Weather Service in Austin/San Antonio notes a warm, moist airmass is locked in place through the day.
Today’s Setup
Skies stay partly sunny with only a 4% chance of rain, so today is dry heat management, not storm-dodging. Overnight lows settle near 77°F under mostly clear skies, offering a modest break before another round tomorrow.
Best Window To Be Outside
Early morning before 10 AM CT and after 7 PM CT are your best bets for yard work, walking the dog around Brackenridge Park, or catching up on outdoor chores. Midday and afternoon hours are when the heat index peaks toward 101, so save the River Walk photo ops or Alamo Plaza visits for the bookends of the day.
Rain, Wind, Fire, Or Heat Risk
No severe weather or flooding is expected locally today — the low rain chances mean flash flood alley stays quiet for now. The bigger concern is heat: forecasters flag heat index values as high as 101, so treat this like an Advisory-adjacent day even without a formal alert. Monday brings a slightly better shot at afternoon and evening storms, mainly across the Hill Country and I-35 corridor, per the NWS discussion, but San Antonio itself should stay mostly dry with another high near 95.
What To Wear Or Bring
Light, breathable clothing and sun protection are musts. Keep a talc free body powder handy if you’re out and sweating through uniforms or gear near Lackland or Fort Sam Houston. A patio umbrella 10ft is a smart upgrade for backyard shade, and a ceiling fan smart remote makes it easy to keep air moving indoors without cranking the AC nonstop.
Weekend Games And Events
Joji brings his SOLARIS tour to Moody Center ATX on Monday, July 6 — grab tickets on SeatGeek and pick up a Joji t-shirt before the show. Dude Perfect’s Squad Games Tour 2026 rolls through Moody Center ATX on July 9; look for tickets on StubHub and gear up with a Dude Perfect t-shirt, Dude Perfect hoodie, or Dude Perfect hat for the family.
Dinner Idea
With heat like this, skip the stove. A cold Thai noodle salad or a build-your-own wrap bar keeps the kitchen cool, and a high-powered blender turns extra fruit into smoothie bowls for dessert. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door, plus grab an insulated tumbler 30oz to keep drinks cold on the patio.
Next Few Days
Monday holds near 95°F with a modest storm chance mainly north and west of the city. After that, the NWS long-term outlook calls for hot, dry weather returning through the work week as high pressure rebuilds, with only a slight uptick in temperatures by Friday.
