Laje do Shock

Niterói, RJ, Brazil
😮‍💨Hold-downs⚠️Shallow🪨Rocks🏝️Remote

Laje do Shock is one of the most dangerous waves in Brazil, a shallow slab near Itacoatiara that breaks over just 3 feet of water. The wave only works on large SW swells and produces thick, square barrels that detonate with terrifying force. Only a handful of surfers have the skill and courage to ride this wave, as the consequences of a wipeout are severe - the shallow rock shelf has ended sessions and careers. This is strictly expert territory.

Frequently Asked Questions

What kind of wave is Laje do Shock?

Laje do Shock is a slab in Niterói, RJ, Brazil, that mostly breaks right.

What swell works best at Laje do Shock?

Laje do Shock picks up swell from the S round to the WSW, and it's best when it's coming straight out of the SSW. It starts working at around 2.5m and handles up to about 7m, with the sweet spot around 4.5 to 5.9m. Period matters too: aim for 16s or longer, as anything under 12s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.

A N wind is dead offshore at Laje do Shock, and anything from the NW round to the NE keeps it clean. The morning is typically the best window, roughly 5am to 10am. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.
