North Atlantic – A marine heatwave of strong intensity is developping off the coasts of Western Europe and around the British Isles.
Mediterranean Sea – The western part of the basin is being impacted by marine heatwaves of strong and moderate intensities.
North Pacific – The marine heatwave, which extends across nearly the entire equatorial belt from 0° to 15°N, remains stable in area but is generally increasing in intensity, reaching severe to extreme intensities off the coasts of Central America.
A marine heatwave of strong intensity is developing off the coasts of Western Europe and around the British Isles.
A marine heatwave of strong intensity is developing in the western part of the basin, especially off the coasts of Maghreb and around the Balearic Islands, and with a moderate intensity off the coasts of France and around Sardinia.
The marine heatwave located at the centre of the ocean is decreasing both in intensity and area, and only some sparse areas of moderate to strong intensity remain.The marine heatwave located at the West of the Mexican Gulf is increasing in intensity. The marine heatwave affecting the Caribbean Sea is decreasing in intensity.
The marine heatwave located at the centre of the basin is decreasing both in area and intensity.
The marine heatwave currently located near 180°W and 50°N remains stable in intensity but is shrinking, especially on its eastern side. In the sea of Japan, the MHW is increasing in area and in intensity.
The MHW which extends across nearly the entire equatorial belt from 0° to 15°N, remains stable in area but is generally increasing in intensity, reaching severe to extreme intensities off the coasts of Central America. The marine heatwave located around the Philippines and Indonesia is decreasing in intensity and area.
The marine heatwave in the central South Pacific around 110°W remains stable in area but is decreasing in intensity around 130°W. The marine heatwave located north of the Fiji archipelago is increasing in intensity. The marine heatwave south of New Zealand is increasing in both intensity and area and now reaches the Western part of the country.
