Global Ocean

North Atlantic

The marine heatwave in the center of the basin around 30°N is decreasing in both area and intensity, with only a few scattered areas of moderate intensity remaining. 

South Atlantic

A moderate marine heatwave is developing near the equator. The marine heatwave near 15°S is decreasing in both area and intensity, with only a few scattered areas remaining in the moderate category. 

North Pacific

The marine heatwave near 180°W and 50°N remains generally stable in terms of extent and intensity, with conditions still ranging from moderate to severe and locally extreme.  The marine heatwave in the center of the basin, extending to the North American coast, is decreasing in intensity around 170°E, where there is a decrease in strong, severe, and extreme categories, and around 120°W, where there is a decrease in strong categories. The marine heatwave is also expanding in extent off the coast of Central America. 

South Pacific

The marine heatwave off the coast of South America is decreasing in both area and intensity, with only a few areas remaining in the moderate category. The marine heatwave near 120°W is increasing in intensity, and the area classified as strong is expanding. The marine heatwave off the Solomon Islands is decreasing in intensity and has moved into the moderate category. 

Indian Ocean

The marine heatwave in the central part of the basin around 10°S is intensifying, with an increase of strong categories. The rest of the marine heatwaves in the basin remain generally stable in both area and intensity, with conditions generally moderate and locally strong.
