Gatlinburg, TN Forecast

Elevations in the park range from approximately 875 feet to 6,643 feet and the topography can drastically affect local weather. Temperatures can vary 10-20 degrees Fahrenheit from mountain base to top, and clear skies lower down do not guarantee equally pleasant weather at higher elevations. Rainfall averages 55 inches per year in the lowlands to 85 inches per year at Clingmans Dome. Some prior planning and weather-wise clothing will help ensure an enjoyable visit during any season.

Spring

March through May: Spring brings with it unpredictable weather. Changes occur rapidly – sunny skies can yield to snow flurries in a few hours. March is the month with the most radical changes; snow can fall at any time during the month, particularly in the higher elevations. Temperatures in the lower elevations have a mean high of 61ºF. Low temperatures, which are often below freezing, have a mean of 42ºF. By mid-April the weather is usually milder. Daytime temperatures often reach the 70s and occasionally the 80s. Below freezing temperatures at night are uncommon in the lower elevations but still occur higher up. April averages over four inches of rain, usually in the form of afternoon showers. May is warmer, with daytime highs in the 70s and 80s and lows in the 40s and 50s. May rainfall averages about 4.5 inches.

Summer

June through August: Summer in the Smokies means heat, haze, and humidity. Afternoon showers and thunderstorms are common. Temperatures increase through the period with July and August afternoon highs in the 90s in the lower elevations. Evening lows are usually comfortable with readings in the 60s and 70s. In the higher elevations, the weather is much more pleasant. On Mount Le Conte (6,593′ elevation), temperatures above 80 degrees are extremely rare.

Autumn

September through mid-November: Clear skies and cooler weather signal the onset of the fall color season. Warm days alternate with cool nights. Daytime highs are usually in the 70s and 80s during September, falling to the 50s and 60s in early November. The first frosts often occur in late September. By November, the lows are usually near freezing. This is the driest period of the year with only occasional rain showers. In the higher elevations, snow is a possibility by November.

Winter

Mid-November through February: Winter in the Smokies is generally moderate, but extremes in weather do occur, especially with an increase in elevation. It is not unusual to have warm temperatures in the low elevations and snow in the higher areas. About half the days in the winter have high temperatures of 50 degrees or more. Highs occasionally even reach the 70s. Most nights have lows at or below freezing. But lows of -20°F. are possible at high elevations. In the low elevations, snows of 1″ or more occur 1-5 times a year. Snow falls more frequently in the higher mountains and up to two feet can fall during a storm. January and February are the months when one is most likely to find snow in the mountains.
