Honestly, if you've spent more than a week in Central Texas, you know the "official" forecast is sometimes just a polite suggestion from the universe. Right now, looking at the 14 day weather forecast austin tx, we are staring down a classic January roller coaster. One minute you’re wearing shorts at Zilker Park, and the next, you’re frantically wrapping your outdoor pipes because a "Blue Norther" decided to crash the party.
As of Saturday, January 17, 2026, the vibe in Austin is... well, it’s dry. Really dry. We’re currently sitting at 49°F with a humidity level of only 15%. That’s desert-level air, people. If your skin feels like parchment paper today, that's why.
The Immediate Outlook: Sun, Fire, and Freezes
Today is basically a warning shot. We’ve got a Red Flag Warning in effect until 8:00 PM tonight. With 15 mph winds coming out of the north and that bone-dry air, one stray spark could turn a backyard BBQ into a local news headline. The high today is hitting 54°F, but don’t let that sunny sky fool you. Tonight, it’s going to get "Texas cold"—meaning 32°F.
Sunday, January 18, is where the swing starts. We’re looking at a high of 62°F and a low of 31°F. That’s a 30-degree jump in a single day. It’s the kind of weather that makes choosing an outfit a legitimate mental health crisis.

The Week Ahead Breakdown
If you're planning your week, here is the raw data you actually need to care about:
- Monday (Jan 19): High of 64°F. Perfect MLK Day weather. It’ll be sunny, but clouds start creeping in by evening.
- Tuesday (Jan 20): The gray returns. High of 55°F. Humidity jumps to 50% as the wind shifts to the east.
- Wednesday (Jan 21): This is your "indoor day." We have a 35% chance of light rain with a high of 62°F. It won't be a washout, but it’ll be messy.
- Thursday (Jan 22): Mostly cloudy with a high of 64°F. A bit of a "meh" day, honestly.
Why the 14 Day Weather Forecast Austin TX is So Weird Right Now
Most people think January in Austin is just "winter," but experts like the folks at the Climate Prediction Center are watching a transitioning La Niña. Basically, we have a 75% chance of moving into "ENSO-neutral" territory this month. What does that mean for your weekend plans? It means unpredictability is the only thing you can count on.
Historically, Austin averages a high of 62.5°F in January. But as anyone living near Lady Bird Lake knows, "average" is a myth. You might get three days of 80°F followed by a week of drizzly 40s.
The Second Week: Colder or Just Wetter?
Looking further out toward the end of January, the patterns start to get interesting. By Sunday, January 25, the humidity is expected to spike to nearly 99%. That usually signals a front moving through. We're seeing projected highs dropping back into the mid-40s by Monday, January 26, with another round of light rain.
If you’re planning any outdoor projects—painting the deck, planting those "winter hardy" flowers—do it before the 21st. After that, the moisture levels stay high, and the "feels like" temperature is going to be significantly lower than what your phone's home screen tells you.
Survival Tips for the Central Texas "Winter"
- The Onion Method: Layer. Always. A t-shirt under a flannel under a Patagonia vest is the unofficial Austin uniform for a reason.
- Hydrate Everything: When the humidity hits 15% like it is today, your house plants and your sinuses are going to suffer. Break out the humidifier.
- The Pipe Panic: If you see a low of 31°F or 32°F in the forecast, you probably don't need to wrap your main lines, but if it stays below freezing for more than 4 hours, it's better to be safe.
- Watch the Wind: North winds at 15-20 mph (like we’re seeing today) make 50°F feel like 40°F. If you're heading to an outdoor brewery, grab the table with the windbreak.
The next 14 days in Austin are essentially a microcosm of Texas life: a little bit of sun, a sudden chill, and just enough rain to keep the cedar pollen from completely taking over your life. Keep an eye on the humidity levels more than the raw temp; that’s where the real "comfort" factor lies.
Next Steps for Austin Residents:
- Check your tire pressure; these 30-degree temperature swings usually trigger those annoying "low pressure" sensors.
- Download a fire weather app or follow the National Weather Service Austin/San Antonio office for Red Flag updates if you live in a high-brush area.
- Plan your grocery run for Tuesday to beat the mid-week rain showers on Wednesday.
