If you’re planning a trip to Music City for the holidays, you’ve probably looked at a weather app and seen those tidy little averages. It says 50 degrees. You think, "Perfect, a light jacket and I’m good."
Honestly? That is a trap.
Nashville temps in December are a chaotic, unpredictable mess that will keep you guessing until the second you step off the plane at BNA. One day you’re walking down Broadway in a hoodie, and the next, a "Blue Norther" screams through the Mid-State and drops the mercury 30 degrees in three hours.
I’ve seen people showing up for Zoo Lights in thin windbreakers because the afternoon was 62°F, only to be shivering by the time they reach the elephant exhibit. If you want to actually enjoy the Christmas lights at Opryland or the Honky Tonk Highway, you need to understand the weird reality of Middle Tennessee winters.
The Decidedly Indecisive Averages
Let’s look at the numbers, but take them with a massive grain of salt. Historically, the National Weather Service puts Nashville’s average December high at about 49°F to 52°F. The average lows hover right around 31°F to 33°F.
On paper, that’s "cool." In reality, it’s a coin flip.
In 2024, we saw highs hit 66°F on December 9th. People were literally wearing shorts. Then, a few days earlier, the low hit 18°F. That is a 48-degree swing in less than a week. This isn't just a fluke; it's the standard operating procedure for the Cumberland Valley.
The geography of Nashville acts like a funnel. We get that warm, moist air pushing up from the Gulf of Mexico, which makes things feel muggy and mild. Then, a cold front slides down from the Great Plains with absolutely nothing to stop it. When those two meet? You get rain, gray skies, and sometimes the kind of "damp cold" that sinks into your bones no matter how many layers you have on.
Will It Actually Snow?
Probably not. But also, maybe.
If you’re dreaming of a white Christmas on 2nd Avenue, the stats are against you. Nashville typically only gets about 1.3 inches of snow for the entire month of December. Most years, the "first measurable snow" doesn't even show up until around December 23rd.
The real danger isn't snow; it's the "Wintry Mix."
Since our ground temperature stays relatively warm compared to the air, we often get sleet or freezing rain. It looks like a light drizzle until you try to walk across a bridge or a sidewalk. Nashville doesn't really do "charming snowstorm." We do "everything is covered in a thin sheet of glass and the city shuts down for 24 hours."
A Quick Reality Check on Extremes:
- Record High: 78°F (Yes, really. T-shirt weather in December).
- Record Low: -10°F (Thankfully rare, but it’s happened).
- The Humidity Factor: December is actually the most humid month in Nashville, averaging around 78%. That humidity makes 40 degrees feel like 25.
What to Actually Pack (The Non-Boring Version)
Forget the "winter coat vs. light jacket" debate. You need both.
You’ve got to dress like an onion. Start with a base layer—something moisture-wicking because if you’re ducking in and out of crowded bars on Broadway, you’re going to sweat. Then add a sweater or a flannel. Top it off with a medium-weight coat that is at least water-resistant.
If you’re doing the Gaylord Opryland "ICE!" exhibit, keep in mind they keep that place at a steady 9°F. They give you a parka, but your feet will freeze if you’re wearing thin socks and fashion sneakers.
Boots are a smart move. Not just for the "Nashville look," but because December is rainy. We get about 4.6 inches of rain during the month. Walking through puddles in canvas shoes is a fast way to ruin your night at the Ryman.
The "Holiday Magic" vs. Weather Reality
Despite the flip-flopping Nashville temps in December, the city is arguably at its best this time of year. There’s a specific energy when the neon lights of the Honky Tonks reflect off wet pavement.
Zoolumination at the Nashville Zoo is incredible, but it’s a mile-long walk outside. If the forecast says 45°F, dress for 35°F. The wind picks up in the open areas of the zoo and it feels significantly sharper.

The same goes for the Music City Bowl. If you’re sitting in the stands at Nissan Stadium, that wind coming off the Cumberland River is no joke. I’ve seen fans from Northern schools come down thinking Tennessee is "The South" and therefore warm, only to end up buying $70 sweatshirts at the gift shop because they’re vibrating from the cold.
Practical Advice for Your Visit
- Check the 24-hour forecast, not the 7-day: In Nashville, a 7-day forecast is basically a work of fiction. Check the hourly "feels like" temp right before you leave your hotel.
- Plan for "The Gray": December is one of our cloudiest months. Don’t expect sparkling blue skies every day. It’s often overcast, which makes the holiday lights pop more, but can feel a bit dreary if you aren't prepared for it.
- The "Sunset Shift": The sun sets early here—around 4:30 PM. The temperature doesn't just "dip" when the sun goes down; it plummets. If you’re out for a late afternoon walk, make sure you have your evening layer with you.
- Embrace the Indoors: If a cold snap hits, Nashville is built for it. We have world-class museums like the Country Music Hall of Fame and the National Museum of African American Music that are perfectly climate-controlled.
Basically, Nashville in December is a choose-your-own-adventure situation. You might get a misty, romantic 55-degree evening, or you might get a biting 28-degree wind that makes you want to hunker down with a hot chicken plate and a bourbon.
Prepare for the latter, and you’ll be pleasantly surprised by the former.
Next Steps for Your Trip:
Check the live NWS Nashville feed 48 hours before you arrive to see if any major cold fronts are moving in. If you see a "Wind Chill Advisory," swap your light layers for a heavy parka and wool socks immediately—those river winds don't play.
