Farmer’s Almanac Predicts First Frost Dates of 2025 for Tennessee

Yeah, I know it’s been one of the hottest summers in the last several years, but I’m still not quite ready for fall. Although, after the sweltering heat we’ve had, the thought of cooler evenings, comfy sweatshirts, and maybe a campfire doesn’t sound too bad. Not to mention that fall also means the return of Friday night lights, colorful leaves.

How to Determine the First Fall Frost

But fall also brings something that gardeners keep an eye on: the first frost. According to the Old Farmer’s Almanac, which uses NOAA data and decades of weather patterns, the first fall frost usually happens when air temperatures dip to around 32°F. Here’s the tricky part, though – frost can form near the ground even if your thermometer is above freezing. In other words, your tomatoes, peppers, and basil could get nipped sooner than you think.

So, when can you expect that first icy morning in Tennessee? Well, it depends on where you live.
