What to Wear in Knoxville in March
March in Knoxville is a transitional month where winter loosens its grip but hasn't fully let go. Daytime highs typically range from the mid-50s to low 60s°F (12–17°C), while overnight lows can still dip into the upper 30s°F (around 3–4°C). The city sits in a valley between the Smoky Mountains and the Cumberland Plateau, which means temperatures can shift noticeably throughout the day and weather can move in quickly. Rain is common, with March averaging around 4–5 inches of precipitation, so expect wet days mixed in with crisp, sunny stretches. Snow is possible early in the month but rarely sticks for long. The smartest strategy is layering: start your day in a thermal base layer or long-sleeve top, add a light sweater or hoodie, and top it with a water-resistant jacket. Jeans or chinos work well for bottoms — leave the shorts at home. Waterproof ankle boots or sturdy sneakers are better choices than sandals. If you're heading to the Smoky Mountains for a day trip, pack an extra layer as temperatures at elevation run 10–15°F colder than in the city.
