There's always waves on the North Coast especially for dawn patrol before the trades kick up. Some pretty heavy waves too. If there is the day with the right swell you can always drive to Rincon or drive to Rincon when the North coast is blown out. Veterans of many trips going back to the 70s clued me in on doing PR this way. Rincon is a nice family trip. A guys surf trip you go to the North Coast. So many waves up there and not just the spots everyone goes to.
