The marine heatwave in the eastern part of the basin is decreasing in extent and remains stable in intensity, with only a few scattered areas in the moderate and strong categories.
The marine heatwave affecting the basin is decreasing in extent while remaining in the moderate and strong categories. The marine heatwave west of Liberia is decreasing in extent, and only one scattered area remains in the moderate and strong categories.
The marine heatwave at 60°S in the Southern Ocean is intensifying, shifting from moderate and strong categories to strong, severe, and locally extreme.
The area covered by marine heatwaves throughout the basin is decreasing. Their intensity remains stable, ranging from moderate to locally strong.
The marine heatwave located between Papua New Guinea and New Zealand is decreasing in intensity. The marine heatwave in the eastern part of the basin near 100°W is decreasing in both intensity and extent. The marine heatwave off the northern coast of Chile remains stable in extent but is increasing in intensity.
The marine heatwave west of Sumatra is increasing in intensity, moving overall into the moderate and strong categories. The extent of the marine heatwave east of Madagascar persists, but its intensity is increasing and now falls within the moderate and strong categories.
