Most of June the sun rises from 4:30 to 4:50, and it's not until late august it rises around 6am again. Sunset is between 9pm and 10pm, civil twilight lasts until 3:42am, and the sun never goes below 12 degrees.
From November to February it doesn't rise until 8am. (and sets around 4pm, astronomical twilight around 6pm)
We have a large roof window that allows morning sunlight to enter our bedroom, and while my brain/body would probably benefit from following the natural daylight cycle, it has the shutters closed for most of the summer.
Nice mild weather with sane sunrise/sunset times all year round is definitely on the list of things I envy about the SF Bay Area.
It's mostly not about the middle of summer. We have fabulous long summer evenings. It's the interim months like right now, where I most miss having that extra time in the evening. I want long evenings every day possible.
