I will give it to you that those special days where it remains 75 throughout the entirety of the day are pretty awesome. However, in 18 months here, I can count those on two hands, and the days where it was comfortable in shorts/tshirt until 8-10 at night number at probably 2.
When you're from the cold Europe like me, the weather in SF is good !
I lived there for a while and I loved it.
The winters are milder than say, Berlin, but at least Europe gets hot in the summer.
Did you miss this summer? It was really nice from August through most of October.
It was, but still, evenings are almost never warm (i.e. above 70) except for a few days in July/August. That makes it easier to sleep, but I do miss warm summer evenings outside.
