What to Wear in Nashville during September?

September features mostly summer weather in Nashville, however, there can be a touch of Autumn by the end of the month.

Summer attire still works well, but also bring along some fall clothes including a sweater, sweatshirt, or windbreaker for the cooler nights and mornings that become more frequent later in the month. 

Also bring some jeans and perhaps a pair of cowboy boots plus an umbrella for the few rainy days.  Don’t forget a good pair of walking shoes for your visit as the downtown district is hilly, so comfortable footwear is a must. 

Things to Do in Nashville during September

There should be plenty of sunny days this month, and the weather will be cooling down a bit, so this would be an excellent time to consider taking a pay-what-you-wish walking tour in Nashville.

If you're visiting on a particularly hot day, don't forget that there's almost always a chance to see a concert at the Grand Ole Opry every single month of the year, including in September!

You can also visit Nashville Zoo with your kids which is an amazing option to spend you day in warmer months.

And be sure to check out some of the tourist discount passes available in Nashville.

This will also be the first month you can expect to see the Tennessee Titans during the pre-season, and Nashville SC will also be playing a few soccer games during this time of year.

September is also the month of the Dragon Boat Festival, which is an excellent family activity appropriate for visitors of all ages.
