Current tides at Ocean Beach. This chart should always be up-to-date. Click the graphic to go through to the originating site, Surf-Forecast.com, where you can get a lot more information about surf, weather, winds, etc. Good site.
(NOTE: This post is part of my coverage of the cliff erosion and collapse at 330 Esplanade Ave, Pacifica. For a complete chronology and links to many more photos see Evacuation underway at 330 Esplanade.)
