San Antonio weather is a mood. Honestly, if you've lived here for more than a week, you know the drill. You wake up needing a parka and by noon you’re looking for a swimming pool. It's weird, it's wild, and keeping track of the san antonio 14 day weather feels a bit like trying to predict a coin toss that’s currently mid-air.
Right now, we are staring down a classic South Texas "double feature." Two cold fronts are moving through this week, starting Tuesday, January 13. The first one is a bit of a tease—breezy winds and some light rain. But the second one? That's the one that’ll make you dig for the heavy wool socks.
What the Next Two Weeks Actually Look Like
If you’re planning a trip to the River Walk or just trying to figure out if you can finally turn off the AC, here is the breakdown of what the atmosphere is cooking up.
The Immediate Chill (Days 1–5)
Tuesday is kicking things off with a high of 61°F and a 90% chance of rain. It’s soggy. It’s gray. But Wednesday, January 14, flips the script. We’re looking at a high of 70°F with nothing but sun. That's the trap! Don't be fooled. By the time we hit Friday and Saturday, a stronger surge of Arctic air is going to drop the lows into the 30s. Saturday, January 17, is looking particularly crisp with a high of only 60°F and a low of 39°F.
The Mid-Forecast Slump (Days 6–10)
Expect some cloud cover to return around Monday, January 19. We might see some light "mist"—that annoying San Antonio drizzle that isn't quite rain but ruins your hair anyway. Temperatures will hang out in the mid-60s for the highs and mid-40s for the lows.

The Late-January Warm-up (Days 11–14)
Looking toward the end of the month, around January 22 and 23, things start to feel "Texas" again. We’re talking highs jumping back up to 73°F. It’s that pre-spring tease that happens every year before February tries to freeze us again.
Why San Antonio Weather is So Unpredictable
Ever wonder why the forecast changes every time you refresh your app? It’s not because the meteorologists are guessing. Well, not entirely. San Antonio sits at a geographic crossroads.
We have the dry air from the Chihuahuan Desert fighting with the humid air from the Gulf of Mexico. Toss in the Balcones Escarpment (the start of the Hill Country), and you’ve got a recipe for atmospheric chaos.
Meteorologists like the team at KENS 5 often point out that mid-January is statistically our most frigid time of year. This is when the "Polar Vortex" likes to take a vacation in Texas. This year, we’re dealing with a weak La Niña. Usually, La Niña means a warmer and drier winter for us. But "weak" is the keyword there. It means the jet stream is wobbly. One week it’s 80 degrees; the next week, we’re wrapping our pipes.

The Survival Guide: Packing and Prep
Basically, you need to dress like an onion. Layers. Lots of them.
If you're visiting for two weeks, don't just bring shorts because it's "the South." You’ll regret it.
- Footwear: Bring comfortable sneakers for the River Walk, but maybe some water-resistant boots if you're here during the rainy start of the week.
- The "Texas Coat": A medium-weight fleece or a light down vest is usually enough. You rarely need a heavy tundra-grade parka unless a freak ice storm hits.
- Skin Care: The humidity drops fast behind these cold fronts. Your skin will feel like parchment paper. Pack a heavy moisturizer and, honestly, some lip balm with SPF. The sun is still strong even when it's 40 degrees.
What to Actually Do Outdoors
Since the san antonio 14 day weather shows a lot of sun between those cold snaps, it's actually the best time to see the city without melting.
The humidity is low. The air is clear.

- Mission Trail: Biking the missions is brutal in July. In 65-degree January weather? It’s perfect.
- The Pearl: Grab a coffee and sit outside. The "north" winds usually die down by mid-afternoon, making the outdoor plazas really pleasant.
- Botanical Garden: Some of the winter blooms are actually pretty stunning right now, and you won't be fighting the summer crowds.
Look, the 14-day forecast is a guide, not a promise. The 7-day is usually solid, the 10-day is a "maybe," and the 14-day is a "hey, this might happen."
Stay flexible. Keep an umbrella in the trunk. And for the love of everything, don't put away your sweaters just because it hits 75 degrees on a Thursday. Texas isn't done with winter yet.
Actionable Next Steps:
- Check the local NWS San Antonio feed every 48 hours to catch shifts in the "second" cold front timing.
- If you’re a gardener, keep the frost blankets ready for the nights of January 16 and 17.
- Plan your outdoor Pearl or River Walk visits for the "sunny window" between Wednesday and Friday this week.
