🌊In 2025, the European ocean region recorded a record high annual average sea surface temperature(SST), the 4th year in a row. The Mediterranean recorded its second-highest annual SST. A record 86% of the European region saw at least one day of ‘strong’ marine heatwave conditions. #CopernicusClimate

SSHWS category is assigned using ONE value: the maximum wind 10 meters above the ocean surface averaged over 1 minute. A hurricane is not a point. Its size (extent of its wind *field*), forward speed, rainfall, potential storm surge, and the landscape it traverses all factor into its impacts. [3/5]
