Coastal Waters Forecast for Northeast Florida/Southeast Georgia
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. Breezy northwesterly winds will briefly diminish across our local waters this afternoon before shifting to northerly and then strengthening overnight tonight and Tuesday morning as Arctic high pressure builds towards the southeastern states. This high pressure center will shift towards the Mid-Atlantic coast on Tuesday evening, resulting in winds shifting to northeasterly on Tuesday night and Wednesday. Weak coastal troughing developing over our near shore waters on Wednesday night and Thursday may develop isolated to widely scattered showers. A weak cold front will then push southward across our area on Thursday night and Friday morning, possibly accompanied by a few showers. High pressure building over the Mid-Atlantic states in the wake of this frontal passage will maintain northeasterly winds across our region late this week and into the upcoming weekend. .GULF STREAM. The approximate location of the west wall of the Gulf Stream as of Jan 18, 2026 at 0000 UTC. 54 nautical miles east of Flagler Beach. 58 nautical miles east of Saint Augustine Beach. 70 nautical miles east southeast of Jacksonville Beach. 71 nautical miles east southeast of St Simons Island.
