The biggest fish I saw yesterday at San Pablo (15+) was actively spawning. It was rolling around with a small male and acting really strange, pointing it's nose towards the bottom and swimming in a circle in this funny position. Fish can move up and down from day to day with the weather this time of year. This weather right now will probably push fish off the beds. Maybe the fish in your area felt it coming and backed off. The fish at San Pablo didn't seem to be too affected. Each lake is different though. Wind can cool the water on one lake but not on another which can also change the mood of the fish.
