Key takeaways

• Tropical Pacific – off the coast of Chile the event increases in intensity and in extent with moderate and strong categories. 
• Tropical Atlantic – in the Caribbean Sea, the marine heatwave located to the center of the basin remains stable. 
• Southern Ocean – The marine heatwave at 60°S decreases in intensity, with moderate and strong and locally severe categories. 

Marine heatwave categories

Tropical Atlantic

The marine heatwave at 60°S in the Southern Ocean decreases in intensity, with moderate and strong and locally severe categories. 

South Atlantic

The marine heatwave around 30°S decreases in extent and intensity with the moderate category. 

Tropical Pacific

The marine heatwave at the Philippines East decreases in extent and superficie wit moderate category. The marine heatwave located between Papua New Guinea and off the Australia coast is decreasing in intensity. The marine heatwave off the coast of Chile increases in intensity and in extent with moderate and strong categories. 

South Pacific

The marine heatwaves around New-Zealand decreases in intensity with moderate catégorie. 

Indian Ocean

The marine heatwave west of Sumatra decreases in intensity and extent, moving overall into the moderate and strong categories. The marine heatwave around of Madagascar decreases in extent. 

Southern Ocean

The marine heatwave at 60°S in the Southern Ocean decreases in intensity, with moderate and strong and locally severe categories.
