Hot, humid conditions and temperatures can reach 90 degrees. Hiking shoes, a hat, water proof jacket and sun screen are good items to pack for a visit to the Great Smoky Mountains. June, July and August have the highest amount of precipitation throughout the year averaging at 5.4 inches/month. Always bring layers because the wide range in elevation may make you want to shed or add a layer unexpectedly.
FALL- September to November
Arguably the most beautiful season of the Great Smoky Mountains is during the fall months where there are warm days and cool nights. Temperatures range from 50-80 degrees, and the magnificent forests are covered in a stunning blanket of yellow, red, and orange.
WINTER-November to February
Winter in the Smokies has temperatures kept moderately at 50 degrees with the exception of the snow covered mountains. Many layers are recommended, but unlike Minnesota, snow only occurs 1-5 times a year here, and usually in at higher elevations.
The Biome of the Great Smoky Mountains is Temperate Deciduous Forest.
SPRING- March to May
Pack lots of layers if you're planning to visit the Great Smoky Mountains in the spring. The weather is very unpredictable, with temperatures starting with below freezing to 80 degrees.
