What to Wear in Knoxville in October
October in Knoxville is Tennessee fall at its most spectacular — the Great Smoky Mountains reach peak foliage, Market Square's outdoor dining is perfect, and temperatures range from 49°F lows to 72°F highs. About 7 rainy days arrive. A medium-weight jacket over fall layers handles both the city's outdoor dining scene and the mountain day trips that make October the most celebrated month in East Tennessee.
October is the month East Tennessee was made for — the Great Smoky Mountains National Park's fall foliage peaks around the second and third weeks, creating one of the most spectacular natural color displays in the eastern United States, with the park's visitor numbers matching those of peak summer. The drive along Newfound Gap Road and the hike to Alum Cave Trail offer views of the entire Smokies ridge in full color, and the scenic overlooks near Clingmans Dome reveal 360-degree panoramas of autumn-colored mountains that stretch to the horizon. Back in Knoxville, Market Square hosts the final outdoor events of the year in October's ideal conditions, and Neyland Stadium's UT football games against SEC opponents carry the full charged atmosphere of college football in its fall element. Knoxville's October wardrobe bridges the city and the mountain experience simultaneously — a comfortable 72°F afternoon on Market Square requires only a light sweater, while a morning hike in the Smokies at 5,000 feet elevation can require a proper jacket, gloves, and layers. The general approach is medium-weight fall layering anchored to the city's conditions (49°F–72°F), with an additional warm layer specifically for mountain day trips where temperatures run 15–20°F colder than Knoxville valley conditions and early snow is possible above 5,000 feet in the second half of October.
