September brings the beautiful fall season to Tennessee with a drop in temperatures and rainfall. Autumn is the driest among all the seasons, and the average temperatures subside in the 51°F (10.6°C) to 85°F (29.4°C) zone. The oppressive heat of summer gives way to the balmy conditions of fall as the intensity of the sun moderates considerably. Humidity levels are a few notches low, and cloud cover is at the thinnest. The conditions are perfect for visiting parks such as the Great Smoky Mountains National Park and David Crockett State Park. The landscape begins to change colors by the end of September, advancing from east to west parts of the states. Orchards are full of apples and pumpkin patches, and corn mazes rule the roost. Evening breezes make driving and biking enjoyable. The fall season sees a rise in tourist numbers and is generally dearer on the wallet than the summer. September is a comfortable time to visit Tennessee.
