The Box is one of the most feared waves on Earth—a mutant right-hand slab that produces square-shaped barrels of terrifying intensity over a barely submerged reef shelf. When solid SW swells wrap into the Margaret River region, The Box jacks up and throws over almost dry reef, creating a wave that's less surfed than survived. Wipeouts are catastrophic, injuries are common, and respect is mandatory. It's a testing ground for the world's best slab riders and a place most surfers are content to watch from the cliff.

The The Box profile favors mid to high tide, ideally between 1m and 2m on the local tide chart. Compare this preference with the forecast tide and local conditions before choosing a session. The profile flags a low-tide hazard below 0.5m.
The The Box profile uses wind from E (90°) as its preferred direction, with an offshore range of 45° to 135°. Wind speed matters too: light winds outside that range can still produce surfable conditions, while strong offshore winds can make takeoffs difficult.
The The Box scoring profile favors swell from SW (190° to 240°), a swell-height range of 1.5m to 4.5m, and a reference period of 18s. These are model inputs, not guaranteed breaking-wave heights or a promise that the surf will suit every ability.
The main season at The Box is Apr-Sep. A secondary window runs Mar, Oct. Winter swells from Roaring Forties. Extremely dangerous slab.
