The summer heat lasts until late September, when cooler weather begins to settle in, bringing with it the color spectacular of changing leaves in the Smokies, which peak in mid to late October, depending on weather conditions such as the amount of rain as well as duration and frequency of cool nights. Snow is possible in the Pigeon Forge Area from late November through late March, but accumulation is not always guaranteed when snow begins to fall.

The Smoky Mountains are a temperate rainforest because when warm moist air from the valley ascends into the cooler air of the mountains, the water vapor in the air condenses and rain falls. The highest elevations in the Great Smoky Mountains are comparable to Canada in terms of weather and even wildlife.
