The First Fog of August Has Arrived—What Mountain Folklore Says About Winter

An old Appalachian tradition says every foggy August morning may hint at a future snowfall.

GREAT SMOKY MOUNTAINS (Smokies.LIVE Storm Center) — The first foggy mornings of August aren’t just a beautiful sight in the Smokies—they’re also the unofficial start of one of the region’s favorite weather traditions.

For generations, mountain families have followed a piece of Appalachian folklore that says, “For every fog in August, there will be a snowfall the following winter.” While it’s not a scientific forecast, it’s a tradition that has been passed down for decades and continues to spark conversation each summer.

Beginning Aug. 1, many longtime residents start keeping a close eye on the morning fog. If dense fog is present around sunrise and reduces visibility to less than a mile, it counts as one “August fog.”

Some old-time farmers went a step further by recording the date of each foggy morning. According to the tradition, the order of those fogs would correspond to the order of winter snowfalls later in the season.

So, if the Smokies wake up to fog on several mornings this month, don’t be surprised if you hear locals joking that winter is already making plans.

Of course, the Smokies.LIVE Storm Center reminds everyone that this is folklore—not a winter forecast. Modern meteorology cannot predict an entire winter’s snowfall based on August fog. Still, the tradition remains one of the most beloved signs that summer is beginning its slow transition toward fall.

Whether you’re a weather enthusiast or simply enjoy Appalachian traditions, August is a fun month to start your own fog journal. Keep track of each foggy sunrise—you might just have something to compare when snowflakes begin flying across the Smokies this winter.

After all, in the mountains, every season has its stories… and August fog may be the first chapter of winter’s tale.
