Bells runs on the Southern Ocean. The prime window is April through October, when deep lows through the Great Australian Bight and the sub-Antarctic latitudes fire long-period southwest groundswell up its window, with July the single most consistent month. Summer is mostly small and flat with cross-shore sea-breezes.

The wave’s calendar is written into the sport: the Rip Curl Pro runs at Easter, catching the front edge of autumn groundswell and the frequent northwest offshore mornings — the longest continuously running pro surfing contest anywhere.

Where the swell comes from

The engine is the Southern Ocean and the Roaring Forties — deep lows through the Great Australian Bight and sub-Antarctic latitudes with a fetch aimed northeast at western Bass Strait, sending long-period southwest groundswell to Victoria. Bells needs that size and period to wrap the offshore ridge and light the Bowl.

Historic swells at Bells Beach

"Big Saturday"

Easter Saturday brought 15-ft Hawaiian faces "stacked to the horizon," the biggest Bells in about twenty years, from a tight deep low off Antarctica — and Simon Anderson won it debuting his three-fin thruster, the moment that design took over surfing.

A giant Rip Curl Pro swell

A classic deep Southern Ocean low was forecast as maybe the biggest Bells in recent memory, running one of the largest contest swells in years.

Dreamy Bowl days

The 59th edition ran multiple days of clean 4-to-6-foot Bells Bowl on a solid southwest groundswell — the documented mid-size classic the wave is loved for.
