Honestly, if you've lived in the Texas Hill Country for more than a week, you know the "wait five minutes" rule about the weather. But right now, things are looking a bit more predictable than usual—at least for the next few days. We’re sitting in that mid-January sweet spot where the humidity has finally taken a hike, leaving us with crisp air and that specific kind of Texas winter sun that actually feels good on your face.
Currently, it's about 55°F outside. It feels slightly cooler, maybe closer to 50°F, because there's a 16 mph wind kicking up from the northeast. If you're heading out to Landa Park or just grabbing coffee at 2tarts, you’re definitely going to want a real jacket.
The Immediate Outlook: Sunny but Cold Nights
Today is about as clear as it gets. We are looking at a high of 55°F with 16% humidity. That’s basically desert-dry for us. But don’t let the afternoon sun fool you. Tonight, the temperature is going to tank down to 31°F. It’s a dry cold, but it’s still freezing.
Tomorrow, Sunday, January 18, is looking like the pick of the week if you like it bright. We’ll hit 60°F for the high, and that wind is going to die down to about 9 mph coming from the southwest. It’s going to be a perfect day to walk the Comal, though the water is probably warmer than the air right now. Speaking of the river, the Comal is currently flowing at about 3.33 feet at the gauge, which is pretty standard for this time of year.

Monday keeps the sunshine streak alive. We’re actually going to see a high of 64°F. It’s that brief "false spring" we get every year before the clouds move back in.

By Tuesday, the vibe changes. The New Braunfels 10 day forecast shows the clouds moving in heavy. We’re looking at a high of 56°F and a low of 43°F. It won't be raining much yet—maybe a 10% chance—but the humidity is going to jump up to 57%.
Wednesday, January 21, is when you’ll actually need the umbrella. We have a 35% chance of light rain during the day. It’s not going to be a washout, but it’ll be that annoying misty stuff that makes the limestone roads around Gruene a little slick. The temperature will hover around 62°F, but with 86% humidity, it’s going to feel damp and heavy.

What This Means for Your Plants and Pipes
Since we are looking at 31°F tonight and 30°F Sunday night, it’s officially time to stop procrastinating on those sensitive plants. If you've got tropicals or succulents out on the patio, bring them in or wrap them. We aren't looking at a deep, sustained freeze like the 2021 nightmare, but a couple of nights at 30°F is enough to turn your favorite hibiscus into mush.
The humidity is the real story here. We go from 18% today to 100% next Sunday. That kind of swing is classic South Central Texas. It’s why everyone you know has a "cedar fever" headache right now. When the wind shifts from the north and then back to the south, it just stirs everything up.
Practical Steps for the Week Ahead
If you’re planning your week, keep Monday for your outdoor chores or hiking. It’s the warmest "dry" day we have left before the moisture returns. Tuesday and Wednesday are better suited for indoor stuff—maybe finally checking out that new spot in the Sophienburg or hitting the library.

Check your tire pressure too. These 30-degree temperature swings usually trigger those annoying "low air" sensors on your dashboard. It’s not a leak; it’s just the air getting denser in the cold.
Basically, enjoy the sun while it's here. The end of January looks like it’s going to be a lot more "grey and drizzly" than "bright and breezy."
