That wave - a 72.2-foot (22.03 m) swell recorded by an Australian buoy, reared up just south of Tasmania in 2012, MetOcean Solutions said.
A buoy in the Southern Ocean may have recorded the Southern Hemisphere's tallest wave this week. A ferocious storm was recorded in Campbell Island, one of the wild southern ocean. The wave was generated by a deep low-pressure system and wind speed exceeding 65 knots.
During the storm recorded by New Zealand, the significant wave height was 14.9m.
The recent storm was so powerful that scientists believe at one point the waves may have even topped 82 feet (25 meters), but it is impossible to absolutely confirm this as the solar device that is used for such measurements only functions at intervals of 20 minutes over the course of a three-hour time period, as Durrant explained.
The World Meteorological Organization does not hold official records on individual wave heights.
"This [new wave] is a very exciting event and to our knowledge it is [the] largest wave ever recorded in the Southern Hemisphere", Tom Durrant, a senior oceanographer with MetOcean Solutions, said in a statement.
In addition, he said the storm moved across the southern hemisphere without any hindrance due to lack of land. And on the night of May 9th, those researchers looked at the numbers that little buoy was sending back and saw something incredible: the largest wave ever recorded in the Southern Ocean.
"Assuming climate models are correct about stronger storms, then we can expect bigger waves as well", Durrant said, The Sydney Morning Herald reported. More than ten times the height of an average Christmas tree.
Brazilian surfer Rodrigo Koxa was recently acknowledged as having ridden the biggest wave ever surfed, a 24.38 metre giant at Nazare in Portugal last November.
