What to Wear in Knoxville in May
May in Knoxville, Tennessee sits in that sweet spot between spring warmth and early summer heat. Daytime highs typically climb into the mid-70s to low 80s°F (24–28°C), while overnight lows can still dip into the mid-50s°F (around 13°C), so layering remains essential. The city averages around 4–5 inches of rainfall in May, with frequent afternoon thunderstorms rolling through the Tennessee Valley — you'll want a packable rain jacket or compact umbrella on hand most days. Humidity starts creeping up this month, making it feel warmer than the thermometer suggests, especially by late afternoon. For daytime, lightweight cotton or linen blend tops paired with chinos, jeans, or casual midi skirts work well. Comfortable walking sandals or sneakers are ideal for exploring Market Square or the Old City, but closed-toe shoes are smarter if rain is in the forecast. Evenings cool off noticeably, so a light cardigan, denim jacket, or thin layer is worth carrying. If you're heading to an outdoor event at World's Fair Park or catching a game, dress in breathable fabrics and plan for the possibility of a sudden downpour. Sun protection — a hat, sunglasses, and SPF — is equally important as the UV index rises sharply through the month.
