Ocean Water Trivia
During the summer months, 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 47°F (in January) and the highest is 88°F (in July).
Temperatures along the southern coast are usually cooler than inland areas during the summer because of the sea breeze.
