Safety Advice from Local U.S. Coast Guard
Rocky Shores and Rising Tides
The California coastline has many steep, rocky cliffs as well as many rocky areas in dangerous surf zones. Surf zones are areas of coastline that experience regular heavy surf conditions, which make it difficult or impossible to get back ashore if you fall into the water. Rocky areas can be especially hazardous during a rising tide. Beach-goers can find themselves stranded on rocks surrounded by water, only minutes after the beach was completely exposed. Rising tides can also quickly trap people in small coves along the beach. The best way to avoid these situations is to be aware of the tidal state and the tidal prediction for the area of your beach visit.
Bay Crossings recommends checking tides on the National Oceanic Atmospheric Association website: www.wrh.noaa.gov/warnings.php?wfo=mtr
Jetty Safety
Jetties are man-made structures (made usually of rocks or concrete) that project outward from shore to deflect powerful waves away from a harbor or coastline. During times of heavy surf the surface of the jetties can become slippery or loose. To avoid falling into the water or onto the rocks, do not climb or hike on jetties. If you see someone stranded on the rocks, call for help.
Remember:
• Be aware of your surroundings.
• Do not underestimate the power of the sea.
• Always tell someone where you will be and when you will return.
• Know how to contact help: Call 911 or the U.S. Coast Guard on marine band channel 16.
