"King tides" will be be happening from Dec 13 - 15. Fortunately no major storms hitting at that time, but Tomales Bay gets extremely high and bay beaches like Chicken Ranch all but disappear. It will also be interesting to see how all that new road work they've done on SFD in the park will hold up. Particularly at Schooner Bay (pictured here).
