San Antonio is about to experience a dramatic shift in weather, with temperatures soaring into the 70s before crashing nearly 40 degrees in just a matter of hours. Residents will need to prepare for rapid changes, as warm, sunny conditions will quickly turn into cold, windy, and potentially wet weather by midweek.
How the Weather Will Change Each Day
San Antonians are used to unpredictable weather, but this week’s forecast is especially wild.
- Wednesday starts with mild temperatures in the 50s, warming up to a comfortable 71°F (22°C) under partly sunny skies. But don’t get too comfortable—a strong cold front will arrive by late afternoon, sending temperatures plummeting into the 30s overnight.
- Thursday will feel dramatically different as wind chills make it feel like the 20s in the morning. Highs will struggle to reach 51°F (11°C), and strong winds will make it feel even colder.
- Friday will remain cool and crisp, with temperatures in the low 50s during the day and dropping to 49°F (9°C) at night. Expect partly cloudy skies with occasional breezes.
- Saturday brings a temporary warm-up, with highs jumping back to 77°F (25°C). But don’t be fooled—another cold front arrives late Saturday night, bringing temperatures crashing down into the upper 30s by Sunday morning.
What Are the Biggest Weather Concerns?
- Extreme Temperature Swings – Going from warm and sunny to bitterly cold in a matter of hours can catch people off guard, especially those who aren’t dressed properly.
- Wind Chill Factor – Strong winds will make the cold feel even colder, especially Thursday morning, when it could feel like the 20s despite actual temperatures in the 30s.
- Light Rain Possible – While not a major storm, spotty showers may develop, leading to slick roads and reduced visibility.
How to Prepare for San Antonio’s Weather Rollercoaster
- Dress in Layers – It may feel like spring one minute and winter the next, so wearing layers will help you stay comfortable throughout the day.
- Watch for Wind Chill – If you’re heading out early in the morning or late at night, bundle up, as the wind will make it feel even colder than the thermometer shows.
- Protect Pets & Plants – The sudden drop in temperatures could be dangerous for outdoor pets and delicate plants. Bring them inside or make sure they’re properly sheltered.
- Drive Carefully – If light rain develops, roads could become slick, especially during the early morning hours when temperatures are at their lowest.

San Antonio is in for one of the wildest weather weeks of the season. Temperatures will swing between spring and winter in just days, leaving many scrambling to adjust their wardrobe and daily routines.
