Jeffreys Bay (Supertubes) Surf Season
Eastern Cape, South Africa · part of the Jeffreys Bay (Supertubes) spot guide
J-Bay is a winter-swell spot. The prime window is April through October, core June through August, when the Southern Ocean storm engine runs at full tilt and the Cape’s persistent west-to-northwest offshore grooms the wrap. Summer trends small and flat with more onshore southeast wind.
The wave’s calendar is why the Corona Open J-Bay runs in July — sitting inside the reliable band of long-period SW groundswell and all-winter offshore. Slater and Fanning share the event record at four wins each.
Where the swell comes from
The engine is the Southern Ocean and the Roaring Forties — deep mid-latitude lows tracking east and southeast of the Cape, plus Cape cold fronts sweeping up from the southwest, each a pulse of SW groundswell. The warm Agulhas Current meeting cold Southern Ocean air adds energy and can spin secondary lows that prolong the fetch.

Return to the world tour
J-Bay came back onto the Championship Tour in classic winter point surf, Mick Fanning beating Joel Parkinson — the reboot of the modern event era.
Fanning’s fourth title
Mick Fanning won his record-equalling fourth J-Bay title over John John Florence in solid, groomed winter groundswell.
The best conditions in event history
Long-period SW groundswell and light offshore produced 8–10 ft faces, multiple perfect scores and Filipe Toledo’s win — widely called the best the contest has ever seen.
The final that was called off
The Corona Open final was halted after Mick Fanning had a shark encounter early in the heat; he was unhurt and the final was cancelled. The surf that event was solid, clean winter J-Bay.
