The marine heatwave in the Gulf of Mexico and the Caribbean Sea is decreasing in intensity and is now mostly in the moderate category. The marine heatwave around 30°W is increasing in extent but remains moderate overall.
The marine heatwave in the center of the basin is decreasing in extent but remains stable in intensity, with moderate and strong categories still present. The marine heatwave in the Sea of Japan is decreasing in intensity and extent, with only a few scattered moderate marine heatwaves remaining. The marine heatwave in the Yellow Sea and East China Sea is decreasing in extent and intensity, shifting from strong to extreme categories to moderate to strong categories.
The marine heatwave present from the Philippine Sea to Indonesia is increasing in intensity with the appearance of strong categories but remains stable in extent.
A marine heatwave is developing off the coast of Chile around 30°S, but also around 15°S, with moderate to severe.
The marine heatwave in the eastern Indian Ocean is decreasing in size and intensity and is now classified as moderate globally. The marine heatwave in the Bay of Bengal is decreasing in size, with only one area of marine heatwave remaining in the north of the gulf.
