Ocean Water
To ensure the quality of the Grand Strand’s ocean water, the communities along these golden shores have enacted a voluntary summer-long water-testing program. Using 20 sites along the coastline, the program meets EPA standards, established in cooperation with the South Carolina Department of Health and Environmental Control.

Over the last 30 years, the lowest temperature Grand Strand ocean water has reached is 47oF (in January) and the highest is 88oF (in July).

Did You Know?
Ocean water temperature along the Grand Strand beaches is about 20 degrees warmer than New York ocean water during the summer months and approximately 10 degrees warmer during the winter months.

Temperatures along the coast are usually cooler than inland areas during the summer because of the sea breeze.
