So I went out on Sunday and Tuesday (the "3x-4x overhead day"). Both days, Westhaven State Park (south of the Jetty) was completely Victory at Sea - a whitewater mess. But both days, the cove was roughly chest (waist to shoulder) and semi-clean. The Groins were not working at all on Sunday and were almost working on Tuesday, but the wind mushed out most of the waves trying to break.
