Coastal Waters Forecast for Northeast Florida/Southeast Georgia...UPDATED

National Weather Service Jacksonville FL

Atlantic Coastal Waters from Altamaha Sound GA to Flagler Beach FL out to 60 nm. Seas are provided as a range of the average height of the highest 1/3 of the waves, along with the occasional height of the average highest 1/10 of the waves. High pressure ridge centered along the Mid-Atlantic coast will push offshore today, with this feature extending its axis southwest along the southeastern seaboard through Friday. Breezy northeasterly winds will gradually diminish by this evening. A developing winter storm system over the central and southern United States late this week and Arctic high pressure building to the north of our region will drive a cold front south across our waters on Friday night and Saturday, with a surge of northeast winds expected to overspread our local waters from north to south early this weekend. A wave of low pressure then develops along this boundary near our region by Saturday night and Sunday. This storm system's warm front will lift northeast across our local waters on Sunday. Another cold front will cross our local waters by Sunday night and Monday, with strengthening north winds forecast in the wake of this frontal passage early next week. GULF STREAM. The approximate location of the west wall of the Gulf Stream as of Jan 21, 2026 at 0000 UTC. 50 nautical miles east of Flagler Beach. 53 nautical miles east of Saint Augustine Beach. 64 nautical miles east southeast of Jacksonville Beach. 71 nautical miles east southeast of St Simons Island.
