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 Box is a slab in Margaret River, Australia, that mostly breaks right. It's on our list of the world's 100 best waves. It's also a renowned bodyboarding wave.
Pro surfing first came to The Box when the Margaret River Pro moved a round there; Jordy Smith and Miguel Pupo surfed the first heat.
The Box picks up swell from the S round to the WSW, and it's best when it's coming straight out of the SW. It starts working at around 1.5m and handles up to about 4.5m, with the sweet spot around 2.8 to 3.8m. Period matters too: aim for 18s or longer, as anything under 14s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.
An E wind is dead offshore at The Box, and anything from the NE round to the SE keeps it clean. The morning is typically the best window, roughly 6am to 11am. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.
The Box is at its best around the mid to high tide, roughly 1m to 2m on the local chart. Below 0.5m it gets dangerously shallow.
The most reliable run of swell at The Box comes Apr to Sep. There's a second window in Mar and Oct too. Winter swells from Roaring Forties. Extremely dangerous slab.
The water at The Box averages around 18°C, so you'll want a 3/2mm fullsuit. It shifts a few degrees through the year, so check the season before you pack.
No. As a slab, it's strictly for experienced surfers. Expect a moderate crowd (5/10) when it's on. One of the most dangerous waves on Earth. Shallow reef, hideous wipeouts.
The nearest airport on our list is PER, then it's roughly a 3.5-hour drive.
The closest breaks we track are Margaret River (4.5 km), Surfers Point (4.7 km) and Gas Bay (9.0 km), handy when The Box isn't working.
