When Does It Start Getting Cold In San Antonio

Let’s be honest, San Antonio summers are like that one friend who doesn’t know when to leave the party. It’s hot, it’s humid, and it feels like July lasts from March to November. You start wondering if you’ll ever get to wear a sweater again without breaking a sweat. So, when does it actually start getting cold here?

Well, the short answer is: not until mid-to-late October. If you’re from up north, this might sound like a cruel joke. Down here, “cold” is anything below 60°F. And that’s just the air—the ground in Texas doesn’t cool off until November.

The slow slide into fall

You’ll feel the first hint around the third week of October. It’s subtle, like when you walk out of the H-E-B and a breeze hits your neck that doesn’t feel like a hair dryer. That’s your first clue. But don’t pack away your shorts yet—the afternoon will still hit 85 and laugh at you.

I remember one Halloween a few years back. I wore a light jacket, and by 9 p.m. I was sweating through my costume. The trick is patience. San Antonio’s cold doesn’t arrive in a rush; it tiptoes in through the back door.

November: the real shift

Here’s the sweet spot: November. Specifically, around the first or second week. You’ll wake up one morning, step outside with your coffee, and actually need a blanket on the porch. The sun still warms things up by noon, but the mornings and evenings get that crisp, clean feel. That’s when you know it’s real.

I’ve got a buddy who waits all year to fire up his charcoal grill again. He says November 5th is his official “cold enough” day. He’ll text the group chat: “It’s 52 degrees, boys. Brisket weather.” And we all know exactly what he means—finally, we can stand near the heat without wanting to faint.

Why you should care (and smile about it)

Look, you care because your utility bill cares. You can finally turn off the A/C and open the windows. San Antonio homes aren’t built for polar bears, but a 68-degree day feels like a luxury spa. Soak it in. Let the air in. Your wallet and your sinuses will thank you.

You also care because patio life becomes perfect. The Alamo City loves an excuse to sit outside. From November through February, every restaurant with an outdoor table is packed. That’s when you’ll see locals wearing puffy jackets and flip-flops at the same time. It’s a look. And it’s ours.

The “cold” that isn’t really cold

Here’s the funny part: San Antonio gets maybe four to six legitimately cold weeks all year. That’s January. The rest is just “chilly with a chance of complaining.” People bust out the parkas when it dips below 45, even though you can still see their ankles in shorts.

I once watched a neighbor scrape frost off his car—for about ten seconds. Then he shrugged, wiped it with his sleeve, and drove off. That’s the energy. We don’t do winter; we do a brief, dramatic intermission.

How you can tell cold is really coming

Pay attention to the creeks. The Guadalupe River gets lower, and the mosquitoes disappear like they’re on vacation. That’s nature’s signal. Also, look for people carrying jackets in their hands all day, never wearing them, just holding them for moral support. That happens around mid-October.

Another sure sign? The pumpkin patches pop up, and the Fiesta fever settles down for a minute. You’ll see folks drinking hot chocolate on the River Walk, even if it’s 75 degrees. It’s less about temperature and more about the feeling of cozy.

What to do with this knowledge

Start planning your “cold month” wardrobe around mid-November. That means layering. A hoodie under a light jacket is the San Antonio uniform. And invest in a decent coffee mug that keeps your drink warm for more than ten minutes—because your car’s heater takes a while to wake up too.

Also, don’t trust the forecast for December. Last year, we had a week of 80°F on Christmas Eve. Then January hit, and we got freezing rain that shut down the whole city for two days. That’s the real cold window: January. Mark it on your calendar as “wear fuzzy socks or else” month.

So, to sum it up

Cold starts arriving in San Antonio around late October when the evenings get that first bite. The real change happens in November, with comfy sweater weather. January brings the heavy stuff, but only for a short time. And by February, we’re already dreaming about 80 again.

In the meantime, enjoy the journey. Watch people wear beanies with tank tops. Embrace the ritual of checking the weather app five times a day. And remember: in San Antonio, “cold” is just a chance to pull out that flannel you bought on sale and feel like a hero. You’ve got this. Start getting ready around October 15th, and you’ll be a pro.
