Best time to visit Knoxville

United States · 20-year averages

October is the best month in Knoxville, scoring 81 out of 100, with January the weakest at 42. The 39-point spread means timing is worth planning around without being decisive. Only 3 months come close to the top, which makes the timing narrow.

August is the warmest month at 31.9 °C and January the coolest at 8.6 °C — a 23.3 °C spread across the year. Around 75 days a year top 30 °C, concentrated in August and the months either side. At the other end, 69 nights a year fall below freezing: the winter here is a real one.

There is a real wet season here. June to July carry the rain — up to 19 wet days in a month — while January, September, October and November drop as low as 9. That 10-day gap is the biggest single difference between a good month and a bad one in Knoxville, and it moves further than the temperature does.

Daylight runs from 9.7 hours in winter to 14.6 in summer, enough to notice on a sightseeing itinerary.

The three strongest months are October, April, May. The one to think twice about is January. Each month below has its own page with rainfall reliability, extremes, daylight and crowd levels.
