I can't tell. The leaves are still green, it's what is considered "summertime" by Bay Area residents - warm, dry and sunny. I'm getting what I guess is an extended summer. I'm not complaining, although I definitely feel like something's wrong. I've lived with Fall my entire life - even in Colorado, the air changed, what few leaves there were showed their color, and, well, you knew when October rolled around. It still feels like, say August to me here - at least the weather is pretty much the same (or a little warmer) than it was when I arrived.
