What to Wear in Knoxville in December
December in Knoxville brings Appalachian foothill winter, with highs averaging 51°F and lows near 31°F — a proper coat and warm layers handle the range from cold mornings in Market Square to cool afternoons along the Tennessee River. About 10 days bring precipitation, often as cold rain with occasional sleet or light snow, particularly when cold air pushes down from the Great Smoky Mountains to the south. A waterproof layer is more practical than a heavy parka on most December days.
Knoxville in December sits between the Appalachian ridges and the Tennessee River, in a valley that captures cold air from the Great Smoky Mountains to the southeast while remaining milder than the higher elevations. Highs average 51°F with lows near 31°F, and about 10 days bring precipitation — most commonly as cold rain, sometimes transitioning to sleet or light snow when temperatures hover right at freezing. Market Square's holiday lights and the Christmas season events at the Tennessee Theatre make the city's walkable downtown core genuinely atmospheric. The local style tendency runs mountain-adjacent practical: a good mid-weight coat over layered sweaters and dark jeans, waterproof ankle boots, and a warm scarf. The proximity to Great Smoky Mountains National Park means locals dress for outdoor readiness year-round — trail shoes and waterproof layers are as common on Gay Street as at the Appalachian Trail trailheads. December offers a narrow weather window for lower-elevation Smokies hiking, but the higher trails at Clingmans Dome and Alum Cave require winter gear and may be closed.

Frequently Asked Questions
What should I wear in Knoxville in December?+
A mid-weight coat over layered sweaters handles most of Knoxville's December range — the 20°F gap between the low 30s overnight and the low 50s in the afternoon requires flexible layering rather than maximum insulation. A water-resistant or waterproof outer layer is practical given the frequent cold rain. Waterproof ankle boots handle Market Square's brick pavers and the Tennessee Riverwalk paths after precipitation. Add a scarf and gloves for the coldest days.
Is December a good time to visit Knoxville?+
Knoxville in December has real appeal for the right visitor. Market Square's holiday events, the Tennessee Theatre's holiday programming, and the city's excellent local food scene along the Old City and Gay Street are all accessible with minimal crowds. The Great Smoky Mountains' lower elevation trails (Laurel Falls, the Cades Cove loop) are accessible in proper gear and carry an atmospheric winter quiet. Higher elevation trails may be icy or closed. Hotel rates are at their annual low.
What shoes are best for Knoxville in December?+
Waterproof ankle boots with a grip sole handle the downtown Knoxville sidewalks and Market Square's brick pavers after rain or light snow. For lower-elevation Great Smoky Mountains trails like Laurel Falls, a waterproof hiking shoe or boot with moderate ankle support handles the wet and potentially icy rock surfaces. Avoid leather-soled shoes on Market Square's brick after rain — the surface becomes slippery quickly.
How cold does it get in Knoxville in December?+
Daytime highs average 51°F, making afternoons comfortable in a good coat. Overnight lows average 31°F, right at freezing — any precipitation that falls in the evening has a real chance of icing over on bridges and sidewalks by morning. About 10 days bring precipitation in December; cold rain is most common, with sleet or light snow possible during stronger cold air intrusions from the north or during Great Smoky Mountains cold air drainage events.
What should I pack for Knoxville in December?+
Pack a mid-weight coat, sweaters and layering pieces, a water-resistant or waterproof outer layer, waterproof ankle boots, a scarf, and gloves. A packable rain layer is useful on days when the coat alone isn't waterproof. If you plan to visit Great Smoky Mountains National Park's lower trails, add wool socks and a waterproof hiking boot. Knoxville's indoor dining and arts scene is warm enough that you'll remove layers often — plan for easy transitions.
