Ocean Water & Tide Chart

There is a water-monitoring program in place to ensure that our beach water is clean and safe.  The surf is tested regularly at 20 sites along the coastline.  If contaminants are detected, a swimming advisory is posted in the affected area.  The greatest risk for pollutants in the ocean water is after a heavy rain.  This is caused when a runoff from lawns and streets may flush out fertilizer, trash, pesiticides or other harmful debris. You should avoid swimming immediately after a rainstorm and near rain runoff areas.  Swimming in contaminated water may result in minor illnesses such as sore throats or diarrhea.

Fun Fact:  During the summer, the ocean water along the Grand Strand is about 20°F warmer than the ocean water along New York beaches.  Over the last 30 years, the lowest temperature Grand Strand ocean water has reached is 47ºF (January) and the highest is 88ºF (July).
