Why San Antonio’s Weather Is Taking a Sudden Turn
The first half of the week is being driven by warm, humid air from the south, but that will change as a strong cold front sweeps through the region on Saturday night. The front will bring cooler temperatures, breezy winds, and rain. It’s a classic case of Texas weather flipping on a dime—so if you’re loving the warm, sunny days, enjoy them while they last.
By Sunday morning, you’ll notice a sharp drop in temperatures, and by Monday, the rain and clouds will make it feel even colder. The good news? The cooler weather won’t last long. By Tuesday, temperatures will start to climb again, giving you a break from the damp and chilly conditions.
How to Stay Comfortable Through the Ups and Downs
- Dress in Layers: With temperatures swinging from the 90s to the 50s, dressing in layers will help you stay comfortable throughout the day. Mornings and evenings will be much cooler, so be sure to carry a jacket.
- Stay Hydrated: The warm and humid conditions early in the week can be deceiving. Carry water with you if you’re spending time outside to avoid dehydration.
- Plan Outdoor Activities for the Early Week: The best days for outdoor fun will be Thursday through Saturday, but plan accordingly, as the heat will peak on Saturday before the cool front arrives.
- Prepare for Rain on Sunday and Monday: The showers may not be heavy, but they’ll linger, so carry an umbrella or raincoat if you’re heading out.
- Keep an Eye on the Forecast: Texas weather can change quickly, especially with a cold front moving through. Check for updated forecasts to stay ahead of any surprises.
What to Expect from the Weekend Showers
Sunday’s showers will arrive as the cold front pushes through the area, bringing cooler, breezier conditions. The rain is expected to be light, but combined with the drop in temperature, it will make for a damp and chilly day. Monday will follow with more showers, and while the rain won’t be constant, the overcast skies will make it feel colder than it actually is.
If you have outdoor plans for Sunday or Monday, consider rescheduling them for earlier in the week, when the weather will be warm and dry.
The Bottom Line
San Antonio’s weather this week is a mix of warmth, sunshine, and sudden changes. Enjoy the summer-like temperatures while they last, because the weekend will bring cooler, wetter conditions. Thursday through Saturday will be your best window for outdoor plans, but once Sunday arrives, it’s time to bring out the sweaters and umbrellas.
By midweek, temperatures will start climbing again, bringing a return to more comfortable conditions. Stay flexible, stay prepared, and enjoy the ride—this is Texas weather, after all.
