About Great Smoky Mountains Weather
Great Smoky Mountains National Park weather is controlled by its elevation as well as its location. The lower areas of the park have generally pleasant springs and falls, moderate winters, and hot and humid summers. Temperatures can be up to 20°F cooler in the upper mountain reaches. Precipitation is high virtually all year at all elevations, with even higher levels at the higher elevations. Most falls as rain, with snows generally not occurring at the lower elevations. The statistics below are taken from Gatlinburg, immediately north of the park.
Visitation Seasons
The spring is an outstanding time to visit. By mid April wildflowers are blooming at the lower elevations, and by the beginning of May spring green is growing all over the park. Water levels are generally higher so the parks streams and waterfalls look their best. Crowds start to arrive towards the end of spring. May is our personal favorite month in the park.
The summer brings heat, humidity, and almost unbelievable crowds. Good experiences can still be had though, particularly by heading down a trail away from the main parts of the park. Balsam Mountain, Big Creek, and Cataloochee are good places to go to avoid the crowds. If you can visit another time, avoid the summer.
The fall is a world-famous time in the park. Sometime between the middle and end of October, peak foliage change occurs, painting the parks massive hardwood forests a rainbow of colors. Crowds during this time rival the height of summer, and parking areas and roads are filled to bursting. The level of scenery more than makes up for this however, and a visit to the park in peak color change is something everyone needs to do at least once.
The winter brings a relative lack of crowds and cool temperatures. Many days can still be comfortable at the lower elevations, while snows may close the highest parts of the roads at times. Many people consider winter the ideal time to visit, especially those fond of waterfalls, where snow, ice, and more open forests can lead to better views.
