Before you think we’re crazy, keep reading to see the science behind our prediction and see when we expect fall colors to start appearing throughout the Smoky Mountains.
Fall is a special season in Gatlinburg, TN and the Smoky Mountains as the temperatures drop, sweet aromas fill the air, and trees turn into an incredibly beautiful display of colors. The fall colors in Gatlinburg are one of the most beautiful sights that you will ever see. Each year, people always ask when the leaves will change color in Gatlinburg and the Smoky Mountains in hopes of planning a visit at just the right time to see the colors at their peak (when they are the brightest). Below, we provide information on what makes the leaves change color, when they normally peak, when the estimated peak color dates are for 2021, and links to live webcams to see what the colors look like. We’ve even provided a video to give you an idea of what the Gatlinburg fall colors look like! We’ve packed everything we could think of into this ultimate guide to the 2021 Gatlinburg fall colors forecast to help you prepare the best vacation possible to the Smokies!
How Leaves Change Color in the Fall
Understanding what makes leaves change color in the fall will give you an idea of how to know when the colors will peak. There’s a long, detailed, scientific explanation available at the USDA Forest Service website, but here’s a basic overview. Leaves begin to change color as days become shorter and nights become longer. That’s the primary catalyst for getting the fall colors developing in the foliage. During the fall, the nights are longer so trees slow down their photosynthesis process (which is what makes leaves green). When photosynthesis comes to a halt, the leaves go from green to a gorgeous display of red, orange, and yellow. Historically, fall colors normally peak in mid-to-late October in Gatlinburg and the Smoky Mountains. Will this year’s peak fall foliage be during that same time? Read on to find out!
The length of day isn’t the only factor, but it’s arguably the most important. Two other major factors are temperature and weather heading into autumn. To get the most brilliant fall colors, there needs to be a string of warm, sunny days with cool (not freezing) nights. This is the perfect recipe for bright, fall foliage so be sure to check weather forecasts for the area you plan to visit to look for a pattern such as that.
Freezing temperatures are the worst enemy for fall colors. If temperatures dip to freezing levels, leaves will brown up almost immediately and begin to fall. So also be on the lookout for a “cold snap” of freezing temperatures and try to get your visit in before it happens!
So When Will the Leaves Change Color in Autumn 2021?
Ah, so the big question everyone wants answered. The answer is often as accurate as guessing the weather… after all, they are both connected. Fortunately for you, we put enormous amounts of time and effort in analyzing all sorts of data to provide you with as accurate of a forecast as possible. We know many of you plan vacations around the fall colors and we hope that our accurate report helps you time the best possible visit this year!
Foliage Forecast: September 17, 2021 – While the weather has been warm and enjoyable, the higher temps haven’t helped foliage get in the color-changing mood just yet. A quick look at the webcams around Gatlinburg show that pretty much everything is still green. There are some cooler temperatures in the forecast for the next two weeks, which look a bit more favorable for fall colors. However, the highs will still be in the 70’s and the rain in the forecast for the next week throws in a slight speedbump as well.
The higher temps and wet weather may very likely delay fall colors, but we still hope to see vibrant colors appear in the highest elevations around mid-October. Once that begins, colors will slowly spread down the mountain and into Pigeon Forge over the following weeks. The biggest things to watch out for are 1) temperatures that dip below freezing or 2) storms with heavy winds. If either of those happen, it will negatively impact foliage. Thankfully, neither are in the forecast in the next couple of weeks…so we’re hopeful for a beautiful fall!
Foliage Forecast: August 16, 2021 – The fall season is getting closer and the Smokies will soon be filled with incredible colors! This year’s weather patterns are looking very similar to last year, which included a wet summer followed by a calm fall & winter. Based on those expectations, our first prediction for the 2021 Fall Color Forecast for the Smoky Mountains is for colors to begin appearing around mid-October in the higher elevations and will work their way down to lower elevations through mid-November…and possibly lingering around until the end of November if we don’t have below-freezing temperatures or heavy storms. As always, the colors will begin to change in the highest elevations first and then trickle down into the valley (Pigeon Forge) over the following weeks. As temperature and weather patterns change, we will update this forecast accordingly. If colder weather approaches before the end of September, it could bring fall colors earlier in October. So stay tuned!
