NC Coast Outlook

Surf Seaweed Forecast

Real-time NOAA buoy observations along the North Carolina coast, turned into a seaweed (Sargassum) risk index using onshore wind, wave height, water temperature, and gusts.

Across North Carolina’s coast, current conditions show low to moderate Sargassum levels, with no recent seaweed sightings reported by the community. As we move through this time of year with water temperatures ranging from 19°C to 26°C and steady onshore winds, minor accumulations remain possible, particularly along the Outer Banks where current indices are highest. Expect moderate wave activity over the next 24 hours, but conditions overall remain favorable for beachgoers as there are no significant impacts currently expected.
