Marine Weather and Tide Forecast for Hilton Head Island, SC

NEAR TERM /UNTIL 6 AM THIS MORNING/
Tonight: High pressure will remain across the Southeast United States, leading to dry and rather quiet conditions for the rest of the night. Temps remain on track and are expected to dip into the upper 40s inland and upper 50s/lower 60s along coastal areas. Latest guidance suggests some hints of patchy fog attempting to develop across Southeast Georgia away from the coast, as a light/calm wind under clear skies favors radiational cooling and coincides with sfc dewpts around 50 during the coolest part of the night.
Patchy fog has been introduced away from the coast across Southeast Georgia as a result to latest trends, but widespread fog is not expected.
