What to Wear in Knoxville in May
May in Knoxville averages 56–79°F with about 11 rainy days — the Appalachian spring at its most lush, with the Great Smoky Mountains' lower elevation trails in full green and Market Square's outdoor scene fully activated. Light layers and a compact umbrella handle the warm but frequently rainy May; the Tennessee River waterfront and the Old City's restaurant patios are at their best in the warm spring evenings between storms.

Based on typical May conditions in Knoxville. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
Knoxville's May is arguably the best month to visit the area — the Great Smoky Mountains National Park's lower trails are fully accessible and carpeted with wildflowers and lush green, the Tennessee River waterfront trail is pleasant and cool in the morning hours, and Market Square's outdoor market and restaurant scene is in full spring activation. Highs average 79°F with lows near 56°F, and about 11 days bring rain — a mix of frontal events and afternoon convective thunderstorms as the Tennessee valley's atmospheric energy builds toward summer. Knoxville's Tennessee casual style finds its most comfortable May expression — light sundresses, flowy tops, and wedge sandals for the Market Square and Old City scene; trail shoes and quick-dry layers for Smoky Mountains day trips. The May wildflower season in the Smokies — particularly the Catawba rhododendron bloom on Alum Cave Trail — is one of the Southeast's most spectacular natural events and worth planning a Knoxville May visit around.

Frequently Asked Questions
What should I wear in Knoxville in May?+
Light layers handle Knoxville's warm but variable May. A light jacket or cardigan for the 56°F mornings on the Tennessee River waterfront; remove it as the temperature climbs toward 79°F. A compact umbrella or packable rain layer is practical given the 11 rainy days. Comfortable walking shoes or sandals handle Market Square's brick plaza and the Old City's walkable blocks; trail shoes are essential for any Smoky Mountains day trips.
Is May a good time to visit Knoxville?+
May is Knoxville's best month — the Great Smoky Mountains' wildflower season peaks in mid-May with spectacular Catawba rhododendron blooms on the Alum Cave and Chimney Tops trails, Market Square is fully activated for spring, and the Tennessee River waterfront is pleasant for morning walks. Book Smokies trailhead parking reservations well in advance — May is the park's most popular wildflower month.
What shoes are best for Knoxville in May?+
Trail runners or hiking shoes are the most versatile choice if any Smoky Mountains hiking is planned — the Alum Cave Trail's rocky terrain and the Laurel Falls path's natural surface are both wet and muddy in May's rain-heavy conditions. For Market Square and the Old City's walkable brick streets, comfortable walking sandals or flat shoes are appropriate. A waterproof hiking shoe bridges both urban and trail use without a change.
How warm does it get in Knoxville in May?+
Afternoon highs average 79°F with lows near 56°F — warm and pleasantly humid. The Tennessee Valley's geography channels moisture, and about 11 days bring precipitation including afternoon thunderstorms. Smoky Mountains elevations are significantly cooler than Knoxville — Clingmans Dome (6,643 feet) can be 20–25°F colder than the valley floor in May, and late-season cold weather events are possible at higher elevations.
What should I pack for Knoxville in May?+
Pack light layers: a light jacket, sundresses or light tops and pants, trail shoes (if hiking the Smokies), and a compact umbrella or rain layer. For Smoky Mountains day trips, add an extra warm layer for high-elevation trails where temperatures are significantly colder. Insect repellent is useful on the Tennessee River waterfront and Smoky Mountains trails in May's warm, moist conditions.
