You’ve lived in San Antonio long enough to know that "winter" is basically a loose suggestion. One minute you're at Pearl in a t-shirt, and the next, you're frantically covering your sago palms because an Arctic blast decided to hop the fence. Honestly, looking at the san antonio weather 2 week forecast, we are right in the thick of that classic South Texas see-saw.
If you stepped outside this morning, Friday, January 16, 2026, it felt pretty decent. We’re sitting at 48°F right now with a high expected to hit a beautiful 72°F. It’s sunny, it’s calm, and you might think the coats can stay in the back of the closet.
Think again.
The Weekend Reality Check
Basically, don't get too comfortable with today's warmth. A cold front is currently eyeing the city like a Spurs fan eyes a playoff spot. By tomorrow, Saturday, January 17, that high of 72°F is going to feel like a distant memory when the mercury struggles to reach 55°F.
The real kicker? The wind. We’re looking at 16 mph gusts coming from the northeast. It’s that sharp, biting wind that makes 55°F feel more like 40°F. If you’re heading to the Pearl Farmers Market or taking the dog to Phil Hardberger Park, you’ll definitely want the heavy hoodie.

Sunday morning is going to be the "frozen hose" moment of the week. We are looking at a low of 32°F. It is officially the first real freeze threat of 2026.
Rain is Joining the Party Next Week
Most people assume San Antonio is just dry and dusty until April, but the san antonio weather 2 week forecast shows some moisture trying to pick a fight.
Monday starts off mostly cloudy with a high of 65°F, which is actually pretty pleasant for MLK Day. But as we drift into Tuesday and Wednesday, things get a bit messy. We’ve got light rain chances creeping up—about 35% by Wednesday, January 21.
Humidity is going to spike to 81% on Wednesday too. It’s going to be that weird, damp cold that just sits in your bones. You know the type. The kind where the windshield gets that annoying film and the humidity makes your hair do things it wasn't meant to do.

A Quick Breakdown of the Upcoming Days:
- Friday (Today): Sunny and a sweet 72°F. Enjoy it.
- Saturday: The front hits. High of 55°F, breezy and much cooler.
- Sunday: Brisk! A low of 32°F and a high of 60°F.
- Monday: Clouds move in, but it warms back to 65°F.
- Tuesday/Wednesday: The "Damp Days." Highs in the low 60s with a chance of light rain.
Looking Toward the End of the Month
If you’re trying to plan a backyard BBQ or a trip to the Zoo for the following weekend, there’s a bit of a silver lining. Temperatures look to rebound into the 70s by Friday, January 23 and Saturday, January 24.
But, because this is San Antonio, there is another dip projected for Monday, January 26. We’re talking about a high of only 51°F with a 40% chance of rain during the day, jumping to 65% at night.
It’s basically a weather sandwich: Warm bread, cold middle, more warm bread, and then a soggy bottom.
How to Not Get Fooled
The biggest mistake people make with the san antonio weather 2 week forecast is trusting the afternoon high. In January, the "feels like" temperature is the only stat that actually matters. When that wind kicks up to 13–16 mph, that 60-degree sun doesn't do much for you in the shade.

Also, watch your plants. While the 70-degree days make the mountain laurels want to think about blooming, that Sunday morning 32°F will zap anything tender.
Next Steps for San Antonians:
- Check your tires: These big temperature swings (72°F to 32°F) are notorious for triggering your "Low Tire Pressure" light.
- Layering is a lifestyle: Wear a base layer you aren't embarrassed to be seen in, because you will be peeling off that coat by 2:00 PM today and then scrambling for it tomorrow.
- Prep the pets: If they usually stay outside, Sunday morning is the time to bring them in or heavily insulate their space.
Stay dry, stay warm, and keep an eye on those northeast winds this weekend.
