Honestly, Nashville's weather is a bit of a mood ring. People think "the South" and immediately picture palm trees and mild breezes.
They're wrong.
Right now, if you're stepping outside in Music City on this Sunday, January 18, 2026, you're looking at a current temperature of 23°F. It’s nighttime, the sky is clear with a few periodic clouds hanging around, and that west wind at 5 mph is enough to make it feel like 18°F. Basically, it’s cold. Not "Southern cold" where people panic over a light frost, but actual, bone-chilling winter.
The Breakdown for Today
If you're planning your day, don't let the sun fool you. Sunday’s high is only hitting 34°F. That's it. The low tonight is dropping to 20°F.

Even though it’ll be sunny during the day, there's a tiny 10% chance of some stray snow flurries. Humidity is sitting at 39% for the day, which keeps the air feeling crisp rather than damp.
Nashville Temperature: The Wild Swing
The thing about Nashville is the variability. I've seen it hit 60 degrees on a Tuesday and then drop a half-inch of ice on Wednesday. It’s a geographic crossroads where the warm air from the Gulf of Mexico decides to have a fistfight with the arctic blasts coming down from Canada.
Most years, January is the coldest month here. The average high is usually around 47°F, but as we’re seeing today, "average" is just a suggestion. We’ve had record lows in the past that hit a staggering -17°F back in 1985. On the flip side, some January days have seen the thermometer climb into the 70s.
Why the "Feels Like" Matters
In Nashville, the raw number on the thermometer rarely tells the whole story. Because we sit in a bit of a basin, the humidity can make 30 degrees feel significantly more biting than a dry 30 in Colorado.

- Wind Chill: Even a 7 mph wind (which we’re expecting today) strips the heat off you fast when it's in the 30s.
- Urban Heat Island: If you're staying downtown near Broadway, it might be 3-5 degrees warmer than the outlying suburbs like Franklin or Hendersonville because of all the concrete and neon.
- Cloud Cover: Clear nights like tonight mean all the day’s heat escapes into the atmosphere. That’s why we’re seeing that drop to 20°F.
What to Actually Wear
If you’re visiting, pack layers. Seriously. You'll want a heavy coat for the mornings and late nights, but if you're heading into a crowded honky-tonk, you’ll be stripping down to a t-shirt in five minutes.
Actionable Next Steps:
Keep an eye on the wind direction. When it’s coming from the West/Northwest like it is today, the cold is here to stay for a bit. If you're driving, be wary of "black ice" on overpasses even if the roads look dry—that 20°F low tonight is more than enough to freeze any lingering moisture. Grab a local coffee, keep the coat zipped, and enjoy the sun while it lasts.
