When to take it off in Chattanooga
Prime season in Chattanooga runs May–Jun, Aug–Oct: those months average doors-off weather on at least half their days.
January, February, March, November and December are the cold side: the average feels-like high sits under 68°F. April hovers just over the 68°F floor (average feels-like high 69°F), so plenty of days still come up short. July runs hot: the average feels-like high is 96°F or more, close enough to the 100°F ceiling that a lot of days go over.
Your limits aren't ours. If you run doors-off at 55°F in a hoodie, or bail the second it hits 85, set your own thresholds in the forecast tool and it'll call each day for Chattanooga against them.
