South Carolina marine forecasts: common questions
Is there a small craft advisory off South Carolina right now?
No advisory or warning is in force in any of the 8 South Carolina marine zones at the moment. Advisories are issued per zone by the National Weather Service and appear at the top of a zone's page as soon as one is posted.
How windy is it on the South Carolina coast right now?
Buoys off South Carolina are reporting 4 to 7 knots, the strongest at Little River Inlet to Murrells Inlet. A knot is 1.15 mph, so 20 knots is about 23 mph. Wind measured offshore is usually stronger than the same wind felt in a harbor.
How rough are the seas off South Carolina today?
The highest seas measured right now are 1 ft off South Santee River to Edisto Beach, out of the 7 of 8 South Carolina zones with a wave-capable buoy nearby. Seas are significant wave height, the average of the highest third of the waves, so individual waves run noticeably higher than the figure.
Who issues the marine forecast for South Carolina?
The National Weather Service, from its Charleston, SC office and its Wilmington, NC office. Each of the 8 zones on this page gets its own bulletin in a legacy teletype format, reproduced here in full underneath the charts and the live buoy readings.
