Site # 60 is a great site. You will love it unless there is a very high tide.
That campsite is vulnerable to flooding when the high tide is over 6'. From 6.0 to 6.4' flooding may occur if there is a storm anywhere in the Pacific Ocean. June 1 is the start of the hurricane season off of SoMexico. These hurricanes are over 1000 miles away but they can generate a swell that makes for high surf in SoCal. The high surf on top of high tide can cause flooding in those low campsites. When the tide is over 6.4', flooding can occur at the peak of the high tide even without high surf.
June 13-16 there are high tides of over 6' with the highest tide being:
2011-06-14 20:33 PDT 6.66 feet High Tide'. I would not camp in sites 59, 60 or 61 during those dates.

Use "La Jolla, Scripps Pier, California" as the closest tide marker.
Don't get me wrong......the flooding is not "Dangerous" flooding. Like, it won't wash your camper away and probably won't get anything but your jack-stands (and anything on the ground) wet. It's just that, if the surf does get into your site, it will be a muddy mess for a few days.
