The City is pretty damn cold in summer. Mark Twain was dead on. However, just on the other side of the bay is the world's greatest public university. And since Berkeley is directly across from the Golden Gate, the prevailing on shore flow keeps it clear of fog most days. Also, it's on a hill so you can do all the climbing you like, or keep going and head to Mt. Diablo.
