MARINE FORECASTS FOR THE BAHAMAS FOR THE NEXT 24 HOURS – 6:00 A.M. EDT, Thursday, August 27th, 2026 – Plus Extended Forecasts

WARNINGS:
A Heat Advisory remains in effect for the Central & Southeast Bahamas as well as the Turks and Caicos Islands.

Severe Weather Risk: There is a slight to moderate risk of isolated strong to severe thunderstorms expected across the Northern Bahamas. The public should monitor for the issuance of any watches or warnings from The Bahamas Department of Meteorology, and boaters should prepare to seek safe harbour once conditions worsen.

Rip Currents: There is a slight to moderate risk of rip currents affecting the eastern and southern shorelines of the Southeast Bahamas. Beachgoers and swimmers are advised to exercise caution when entering the water.

GENERAL SITUATION:
Gentle to fresh easterly winds will continue to support moderate seas across Atlantic and exposed eastern waters, while sheltered banks remain slight, due to the influence of strengthening high pressure throughout the period. Showery and unsettled conditions will persist through the first half of the day, mainly across the Northern Bahamas, due to the interaction of a tropical wave south of Cuba with a broad upper-level disturbance, with gradual improvement as weather shifts out of the area by late tonight.

OUTLOOK:
Expect the current sea state to persist, as the surface ridge maintains its wind regime over area waters. Passing showers with thunderstorms will continue through the weekend across the Bahamas, with additional activity anticipated for the northern territorial waters by Saturday, as a frontal boundary sinks southward towards the area.
