When to take it off in San Francisco
No month in San Francisco averages doors-off weather on half its days. The best stretch is October, at 10 days.
January, February, March, April, May, June, July, August, October, November and December are the cold side: the average feels-like high sits under 68°F. September hovers just over the 68°F floor (average feels-like high 68°F), so plenty of days still come up short.
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 San Francisco against them.
