Key takeaways

• Tropical Atlantic – decreasing intensities and extent of the affected area.
• Tropical Pacific – intensification of the marine heatwave between Papua New Guinea and New Zealand now at severe categories. A marine heatwave is developing off the northern coast of Chile. 
• Indian Ocean – marine heatwave at 60°S (Southern Ocean) is intensifying reaching extreme categories.

Tropical Atlantic

The extent and the intensity of the marine heatwave impacting the basin are stable in moderate to strong categories, except for marine heatwave along the African coast around 15°N which is diminishing in both intensity and area, and is now in moderate category.
