Typical Temperatures in Knoxville During September

When considering Knoxville weather in September, understanding the typical temperatures is crucial for planning your activities and packing appropriately. Generally, you can expect average high temperatures to hover around the low 80s Fahrenheit (approximately 27-28 degrees Celsius). These daytime highs are usually quite comfortable, especially when compared to the sweltering heat of July and August. The humidity also begins to decrease, which makes the higher temperatures feel more bearable. Mornings and evenings, however, bring a refreshing change.

To put it simply, think layers! During the day, you might be comfortable in short sleeves and light pants or shorts. However, as the sun begins to set, you'll likely want to have a light jacket, sweater, or long-sleeved shirt readily available. This will help you stay comfortable as the temperatures drop. Keep in mind that these are just average temperatures. There can be variations from year to year, and even from day to day. Some Septembers might be warmer overall, while others might be cooler. Checking the forecast closer to your travel dates is always a good idea to get a more accurate picture of what to expect. But, in general, you can anticipate a pleasant mix of warm days and cool nights, making September a particularly appealing time to visit Knoxville.

What to Wear in Knoxville in September

Knowing what to wear when visiting Knoxville in September can make your trip more enjoyable.

Fabrics like cotton, linen, and moisture-wicking materials will help keep you comfortable, especially if you plan to be active outdoors. Sunglasses and a hat can also be useful for protecting yourself from the sun.

However, as evening approaches and the temperatures begin to drop into the high 60s Fahrenheit, you'll want to have some warmer options available. A light jacket, sweater, or long-sleeved shirt is perfect for layering over your daytime clothing. This will allow you to adjust to the changing temperatures and stay comfortable throughout the evening. If you plan on spending time outdoors at night, you might even want to consider bringing a slightly heavier jacket or a fleece. Closed-toe shoes are also a good idea, especially if you plan on doing any hiking or exploring. And, as mentioned earlier, it's always wise to pack a light raincoat or umbrella, just in case you encounter a shower. By dressing in layers and being prepared for a range of weather conditions, you'll be able to fully enjoy all that Knoxville has to offer in September, without being caught off guard by the changing temperatures or occasional rainfall.
