Springtime in the Smokies is an unstable time
for both temperature and precipitation. It can be sunny and
mild one day - then snow the next. Backcountry hikers should
be prepared and dress in layers--certainly take cold-weather
clothing. By mid-April, the weather has stabilized (see the
By mid-June it will be hot and humid. Drink plenty
of fluids. If hiking, carry water with you - do not drink from
streams, no matter how fresh and clear it appears. Afternoons
are often accompanied by thunderstorms. Temperature drops combined
with altitude can mean a 10-degree difference in temperature,
so it would even be a good idea to have a wool sweater along.
By September, the days are mild and the nights
cool and crisp. Light snows can occur at higher elevations.
However, it's these very cool nights that change the chemistry
in deciduous foliage to create autumn's color extravaganza!
Winters are relatively mild in the Smokies,
but winter days are subject to change dramatically. One day
can be spring-like, while the next might bring temperatures
in the 20s with several inches of snow. The upside is that defoliated
trees allow for great mountain vistas and very private hikes.
