Shipstern Bluff Surf Season
Tasmania, Australia · part of the Shipstern Bluff spot guide
Prime is the Southern Ocean winter and shoulder, roughly April through October and core May to September, when deep Roaring Forties lows track close to Tasmania and fire long-period south-to-southwest groundswell straight at the peninsula. June and August are the best overall months and autumn can deliver the cleaner, more organised days. Even in season, the marquee wave needs a big, long-period swell to line up in a short window — this is a call-it-on wave.
Where the swell comes from
Deep Southern Ocean and Roaring Forties lows spinning up between Australia and Antarctica, whose enormous unobstructed fetch delivers the long-period south-to-southwest groundswell the slab needs.
Historic swells at Shipstern Bluff
Red Bull Cape Fear
A big-wave slab invitational was staged at Shipsterns during a Southern Ocean swell — the best-documented anchor for the wave, run on a call-it-on basis when a big enough long-period swell lines up.
