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. High pressure over the southeastern states will briefly weaken tonight and will then be reinforced by another high pressure center on Sunday and Monday. This high pressure center will slowly shift off the southeastern seaboard by late Tuesday, followed by a cold front dropping southward down the southeastern seaboard by late in the week. Swells from distant Hurricane Sam will likely arrive late in the week as well. GULF STREAM. The approximate location of the west wall of the Gulf Stream as of Sep 25, 2021 at 1200 UTC. 58 nautical miles east of Flagler Beach. 68 nautical miles east of Saint Augustine Beach. 81 nautical miles east of Jacksonville Beach. 99 nautical miles east southeast of St Simons Island.
