Weather in Silicon Valley

Never thought I'd say this, but the weather in mid-state California--at least in Sunnyvale in the summer--is boring! Every day is the same. In the early morning, it is quite cool with clouds and major overcast coming over the Santa Cruz mountains...then the clouds break up, the sun comes out, and the temp rises to...oh...maybe low-to-mid-70s. Low humidity. Zero rainfall in June and July. It's beautiful, of course...but the lush green of March has given way to brown mountains except where irrigated. I can see how brush fires happen. If I lived there, I would have a sweatshirt and a blanket permanently placed in my vehicle!
