Forte de Copacabana Posto 6.

Forte de Copacabana is the sheltered southern corner of Copacabana beach at Posto 6, directly in front of the Fairmont hotel, where the fort's headland blocks the southwest wind and strips the power out of big swells. Most days the corner sits flat, left to swimmers and stand-up paddlers, but when a solid pulse from the south, southeast or east gets in, long, mellow rights peel off the point at 0.5 to 1.0 m, best with the tide drained right out. That shelter makes it the city's defensive call: when a big swell maxes out Barra and the open beaches, the corner keeps a friendly, makeable right that beginners and intermediates can enjoy while everything else closes out. Off the fort's seaward face lies the Laje do Shore, a barely submerged rock shelf that turns the same swell into a hollow, punishing shorebreak. Bodyboarders treat it as a rite of passage: the ledge is crusted with shellfish, earned the nickname Expresso Escorpião, and most regulars carry a scar from it. Getting in is a simple walk down the public sand at Posto 6, and midweek the laje is often ridden by only a handful. When the corner is flat, Diabo and Arpoador around the point pick up far more swell.

The fort keeps this corner asleep until a south swell wakes long rights and the shellfish-crusted ledge they call Expresso Escorpião.
