I'm glad you posted those pics cause the sky looks grey... just like the North East of England... I usually get jealous of all that California sunshine!
That was pretty early in the morning, it got sunny later in the day.
California's overrated in terms of its weather though. South Cali is sunny but it's hot as hell and you want to spend your time inside a building with AC rather than go out in it. A lot of north Cali is cloudy/rainy with a sprinkle of sun from time to time, especially where I'm at.
