If you're looking at a 30 day forecast for Gatlinburg Tennessee, honestly, you've probably already realized it's a bit of a moving target. January and February in the Smokies are notorious for being a weather "mood swing" season. You might wake up to a postcard-perfect dusting of snow on the Pines, only to be eating lunch in 50-degree sunshine a few hours later.
Basically, planning a trip based on a long-range look requires a bit of nuance and a healthy respect for elevation changes.
Right now, as of January 18, 2026, we’re seeing a classic winter pattern. The current temperature is sitting at 33°F, but it feels more like 27°F thanks to a steady 7 mph breeze coming off the mountains. It’s sunny, which is great for visibility, but don't let the blue skies fool you. The ground is cold, and the air is dry.
The Reality of a Gatlinburg Winter
The biggest mistake people make? Assuming the weather downtown on the Parkway is the same as the weather at Newfound Gap. It isn't. Not even close.

Temperatures can drop by 10 to 20 degrees as you climb toward the higher peaks. While Gatlinburg itself averages a high of 49°F and a low of 26°F in January, the mountains are a different beast entirely. Up at nearly a mile high, Newfound Gap sees an average of 69 inches of snow over the winter season. Downtown? You’re lucky to get a few inches that actually stick for more than a day.
Looking ahead at the next few weeks:
- Jan 19–21: Expect clear, sunny days. Highs will hover in the mid-30s to high 40s, but Monday night is going to be a "stay inside by the fireplace" kind of night with a low of 14°F.
- Jan 22–24: We're looking at a shift. There’s a 35% chance of snow on Thursday, with temperatures dipping back into the 20s at night.
- Late January (Jan 25–31): This is where it gets messy. We’re seeing a mix of rain and snow showers. Expect a significant wet system around Jan 26 with a 75% chance of rain followed by snow showers as the cold air moves back in.
Why the 30 Day Forecast for Gatlinburg Tennessee Shifts
Long-range models like the ones used by Almanac and AccuWeather suggest that the end of January 2026 might be influenced by a polar vortex surge. This means while the monthly average might seem "mild" at 45°F, the actual experience will be a series of sharp peaks and valleys.

February is historically a bit warmer, with an average high of 53°F, but it’s also the month where you’re most likely to see a heavy, sudden snowstorm in the park. The "Deep South" long-range forecast predicts heavy rain in early February, which often turns into "the white stuff" once it hits the Tennessee-North Carolina border.
Honestly, if you're coming for Wilderness Wildlife Week (starting Jan 27), you need to pack for every possible scenario. One day you’ll be hiking in a light fleece, and the next you’ll need a heavy parka and waterproof boots.
Packing and Prep Tips
Don't trust the "sunny" icon on your phone too much.

- Layers are everything. Wear moisture-wicking base layers. Cotton is your enemy here because if it gets damp from sweat or light mist, it stays cold.
- Check the Ober Gatlinburg report. Even if there isn't natural snow, the ski resort is usually making its own. Currently, they’re reporting a top snow depth of 45 inches and have been making fresh snow as recently as yesterday.
- Footwear matters. If you're hitting the trails, ice patches are a real hazard even on 40-degree days. Micro-spikes or at least sturdy boots with deep lugs are a must.
The 30 day forecast for Gatlinburg Tennessee shows a trend of "sunny but chilly" transitioning into a "wet and wintry" end of the month. Keep an eye on the wind chill, especially if you're heading to Anakeesta for Astra Lumina—those mountain-top winds make 30 degrees feel like 15 real quick.
Keep your plans flexible. If a storm rolls in, the National Park Service often closes Newfound Gap Road (US-441) for safety. Have a "Plan B" that involves the aquarium or the local distilleries downtown.
Before you head out, check the Great Smoky Mountains National Park Twitter/X feed or the NPS website for real-time road closures. They are the only ones with the most accurate, boots-on-the-ground info for the higher elevations.
