Savor September

Typically in Chattanooga, September’s temperatures fluctuate between an average high of 81.9° + an average low of 61.2° during the nights — making temperatures ideal for outdoor activities. Not a fan of the rain? Good news. Historically, September is the month with the least amount of rainfall in the Scenic City.

Cool down in October

Get your cameras ready, October is a picturesque month in Chattanooga when the autumn colors really start to pop. We were even ranked as one of the top spots in the US to see fall colors. The average high temperature drops to 70.2°, and generally, the average low temperature is 49.3°. October also tends to be one of the least humid months of the year — we’re already sighing with relief.

November’s numbers

Historically, temperatures in November fluctuate between 40.1° + 57.6°. It’s also usually the first month past summer to see any snowfall — but with a greater chance of high temps this year, that might not happen.
