NOAA scientists have tracked a steady climb in ocean temperatures since April 2023, which is causing unprecedented heat stress conditions in the Caribbean Basin, including waters surrounding Florida and in the Gulf of Mexico.
More isolated marine heat wave conditions have been detected off the Northeast U.S. coast, along the path of the Gulf Stream. NOAA has also been monitoring a large marine heat wave in the Northeast Pacific (in the Gulf of Alaska) that has been sitting offshore since late 2022.
