The bigger picture is just as important as the headline numbers. Long-term analyses of global wave records show that about one third of the world ocean has experienced clear upward trends in mean and extreme wave heights since the 1980s, especially across the Southern Ocean, where winter waves have been rising by roughly one to two centimeters per year. In that belt, average wave heights increased by about 30 centimeters between 1985 and 2018, and overall wave power has climbed around eight percent since the 1980s.
