Smoky Mountains Weather
Know Before You Go!
Smoky Mountains weather can be very unpredictable, just like the weather anywhere else. Since the Smokies are the tallest and most massive mountains in the eastern U.S., they're also colder and wetter than the surrounding areas of the park.
When you're hiking, remember that the air temperature decreases as the elevation increases. This can be a good thing when you're sweating as you climb up a mountain. :)
There's about a 3º drop for every 1,000' you ascend. Precipitation also increases with elevation.
Rainfall in the Smokies is greatest in the summer. In the Smokies, the nights are colder, spring arrives later, and fall comes earlier than the area around it. I recommend checking the forecast before you go, but no matter what, always be prepared with a poncho when you hike.
In general, here's what to expect for Smoky Mountains weather:
--March-unpredictable and rapidly changes, temperatures often drop below freezing at higher elevations
--April-major blizzards can come as late as early April
--middle to late April becomes more mild
--May-typically highs are 70s-80s and lows are 40s-50s
--by mid-June it's hot and humid

--clear skies, but cool, rainy days still possible
--in September, days are typically 70s-80s, 50s at night
--In November, days are typically 50s-60s, lows are near freezing
--higher elevations may get snow
--days usually have a high of 50º, nights are usually at or below freezing
--if you're looking for snow, visit in January-early March
As you can see, weather in the mountains can vary greatly. I recommend visiting the Smokies in
My favorite times to go are May and October. No matter when you go, you'll be in for a treat out on the trail!
