Key Takeaways

• Mediterranean Sea : marine heatwave is decreasing in both intensity and extent presenting moderate categories.
• North Tropical Atlantic: marine heatwave in the Gulf of Mexico is increasing in intensity with strong and locally severe categories. The areas of the North of the Antilles is now less impacted by marine heatwave conditins.
• North Pacific : in this Ocean basin, the marine heatwave between the Japanese and the North American coasts in decreasing in extent while gaining in intentisiy. While the marine heatwave in the Yellow Sea, in the East China Sea and the Japan Sea is increasing in both size and intensity.

North Tropical Atlantic

The marine heatwave in the Gulf of Mexico and in the Caribbean Sea is intensifying with a greater proportion of strong categories and locally severe. North of the Antilles, the area of the marine heatwave has diminished. The marine heatwave extent around 30°W and near the equator is stable but its intensity is increasing, and is now mainly in strong category.
