If you love unpredictable weather, San Antonio is about to deliver an exciting week of surprises. A strong cold front is on the way, bringing a temporary cool-down midweek before temperatures skyrocket toward the weekend. That means you’ll need a jacket early in the week, but by Saturday, it’ll be time to break out the shorts and sunscreen.
Starting Monday, temperatures will be mild and comfortable, but by Tuesday night, the cold front will bring gusty winds and a noticeable drop in temperatures. Wednesday morning will feel chilly compared to San Antonio’s usual warmth. However, once the front moves out, a rapid warming trend begins, sending temperatures soaring into the mid-80s by the weekend.
What’s Behind San Antonio’s Wild Temperature Swings?
This week’s dramatic weather changes are caused by a strong cold front moving across Texas. As cooler northern air pushes south, it will bring gusty winds and a temporary drop in temperatures. However, San Antonio won’t stay cold for long. By Thursday, a high-pressure system will build, bringing back sunshine and much warmer conditions heading into the weekend.
Here’s what to expect:
- Early in the week: Mild and breezy with increasing cloud cover.
- Tuesday night into Wednesday: The cold front arrives, dropping temperatures by 10-15 degrees.
- Thursday and beyond: Rapid warming begins, pushing highs into the mid-80s by Saturday.
