In March, Knoxville averages highs of 62°F and lows of 39°F with about 13 rainy days — transitional Southern Appalachian spring with warm afternoons and cold mornings. The Great Smoky Mountains National Park is beautiful in March as wildflowers start blooming, but elevation brings dramatically colder temperatures above 3,000 feet. A waterproof jacket, comfortable walking shoes, and warm layers handle both the city and the mountains.

Based on typical March conditions in Knoxville. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
March in Knoxville bridges late winter and early spring in the Tennessee Valley — highs averaging 62°F, lows at 39°F, and 13 rainy days that are often misty mountain weather rather than hard storms. The Great Smoky Mountains are within an hour's drive and genuinely beautiful in March as trout lilies and hepatica begin blooming, but mountain hiking requires real layers: temperatures at Clingmans Dome (6,643 feet) can be 25–30°F colder than Knoxville. Market Square and the Old City neighborhood are walkable and charming even on rainy days. Tennessee-casual with an outdoorsy Appalachian edge defines Knoxville style, and March rewards the functional end of that aesthetic: a mid-weight waterproof layer that handles misty mountain conditions, comfortable walking shoes with grip for wet mountain trails, and layered pieces that adapt from the city's 62°F afternoons to the mountains' much colder elevations. UT campus energy and the Market Square farmers market atmosphere favor practical-comfortable over dressed-up.
A black rain jacket over an oversized graphic tee and olive cargo trousers handles mild rain practically. White lace-up booties finish the look with enough contrast to lift the palette.
A grey longline coat over an ivory blouse and black wide-leg trousers handles mild rain without losing formal intent. Black Chelsea boots and a mini bag keep it focused.
A black longline parka over a cable knit sweater in mild rain keeps warmth without overdressing. Black mule heels under leggings are an unexpected and intentional detail.
A navy trench coat over khaki bermuda shorts and a blue linen blouse works between seasons on a mild rainy day. Black pointed-toe heels sharpen what could easily be too casual.
A cream oversized puffer over a navy striped cardigan and wide-leg ivory linen trousers handles mild rain with a considered mix of textures. Black ballet flats are the restrained finish.
An olive anorak handles mild rain without abandoning the polish of wide-leg navy trousers underneath. The crossbody stays tucked and close.
A blush cropped jacket over a grey cardigan and black sweater mini skirt handles mild rain with charm. A black bucket bag and ankle boots keep the proportions balanced.
Knoxville in March averages 62°F highs and 39°F lows with 13 rainy days — mid-weight layers, a waterproof jacket, and comfortable walking shoes cover most needs. If visiting the Smoky Mountains, bring real cold-weather layers; mountain temperatures run 25–30°F colder than the city. Waterproof footwear handles wet trails and city sidewalks.
March is a lovely time to visit Knoxville, especially for Great Smoky Mountains access before summer crowds arrive. Wildflowers begin blooming in the park in March and April. The city's Market Square, Tennessee Theatre, and Old City are enjoyable in any weather. The 13 rainy days are generally manageable misty weather rather than heavy storms.
Waterproof walking shoes or boots with grip work best for Knoxville in March — both wet city sidewalks and mountain trails benefit from water resistance and traction. For Smoky Mountain hiking specifically, waterproof hiking shoes handle the wetter, colder conditions at elevation. Save lighter footwear for warmer, drier spring days.
Knoxville averages a low of 39°F in March, with mornings requiring a real coat. The Great Smoky Mountains run dramatically colder at elevation. Highs average 62°F, which is pleasant for afternoon outdoor activity in the city. The Tennessee Valley's 23°F daily swing requires adaptable layering.
Pack mid-weight layers, a waterproof jacket, and waterproof walking shoes for Knoxville's March. If visiting the Smokies, add warm base layers and a heavier jacket for mountain temperatures. The 13 rainy days make a compact umbrella or packable rain jacket useful. The outdoorsy-casual Tennessee aesthetic rewards functional, comfortable layers.
