Climate -- Summer is the peak tourist season in Nashville but is also when the city experiences its worst weather. During July and August, and often in September as well, temperatures can hover around 100°F, with humidity of close to 100%. Can you say "muggy"? Spring and fall, however, last for several months and are both quite pleasant. Days are often warm and nights cool, though during these two seasons the weather changes, so bring a variety of clothes. Heavy rains can hit any time of year, and if you spend more than 3 or 4 days in town, you can almost bet on seeing some rain. Winters can be cold, with daytime temperatures staying below freezing, and snow is not unknown.
