Great Smoky Mountains Tennessee, USA Travel Guide

Best Times to Visit

Climate patterns vary throughout the year. Spring (March-May) temperatures generally range from 40-70°F (4-21°C) with moderate precipitation and frequent rain. Wildflowers begin to bloom in late April to early May. Higher elevations remain cooler, and snow is possible into April.

Summer (June-August) temperatures typically range from 60-90°F (15-32°C). Lower elevations can be hot and humid, while higher elevations are often 10-20°F cooler. Afternoon thunderstorms are common. Fall (September-November) sees temperatures from 30-70°F (-1-21°C), with lower precipitation and crisp air. Peak fall foliage typically occurs from mid-October to early November. Winter (December-February) temperatures are 20-50°F (-6-10°C), with snow and ice common at higher elevations, leading to road closures.

Ideal Timing for Activities

  • Wildflower Viewing: Late April to early May for spectacular displays.
  • Hiking: Spring (April-May) and Fall (September-October) have comfortable temperatures and fewer insects.
  • Wildlife Viewing: Dawn and dusk are best year-round in Cades Cove and Cataloochee Valley.
  • Synchronous Fireflies: Late May to mid-June, access by lottery system.

Special Weather Considerations

Elevation makes an impact: Temperatures vary by 10-20°F (5-11°C) from lowlands to peaks. Weather at higher elevations is often unpredictable. Fog often creates the "Smoky" name but can reduce visibility. Snow and Ice are common in winter above 3,000 feet, closing roads. Flash Floods may occur after heavy rains; avoid low-lying areas. Wildfires increase risk during dry periods, leading to closures.

Always pack layers, regardless of the season. Mountain weather changes quickly, and temperatures vary greatly from low to high elevations. A Waterproof jacket is a wise addition to your bag.
