How large do waves get in the southern ocean and are they the largest in the world?
On average, yes, the Southern Ocean has the largest continuous waves in the world, due to the almost completely un-interrupted flow of the Antarctic Circumpolar Current, which is the largest current in the world (by a lot). Couple this flow with a turbulent bottom and the winds of the “Screaming 60s” (latitude), and In bad storms, you can have waves at 60 feet or more (observed at 90+ feet) However, the “rogue waves” that can occur *anywhere* in the World Ocean have the capability of being higher.
