Cave

Cave is an exposed reef break in the Ericeira area, producing a powerful right-hand wave that is often described as fast, hollow, and very intense. It breaks over an extremely shallow reef/ledge, giving almost no margin for error—conditions can go from promising to hazardous quickly, especially because the wave can start suddenly on a shallow section. When it’s on, the wave character is reported as world-class/epic, with fast peeling and heavy barrels. The spot is widely treated as an expert-only destination. Hazards are not limited to the reef itself: reports include sharp rocks, submerged boulders, and sea urchins, alongside strong rip currents and powerful water movement over the reef. Entry and exit are described as dangerous, and localism is reported as heavy—observers are advised to watch from the cliffs for a long time before attempting to paddle out, and to only enter with the necessary skill. Timing matters. The spot is reported to work best around December in one dataset, but another source recommends Autumn and Winter for consistent swell and offshore wind conditions. Multiple tide references conflict: baseline data lists low tide as best, while another source indicates best performance on mid to high tide and on rising/falling tides. Given that low tide can be “lethally shallow” and high tide can become too deep, the safest approach is to verify tide and timing against the actual set behavior. Operationally, Cave is associated with northwest swell and east to North-East wind. It’s described as needing a significant swell to start working properly (reported as at least about 2 meters) with swell ranges that can go up to very large sizes. Due to the extreme danger and limited rescue/lifeguard coverage reported for this exact spot, plan around conservative entry decisions and ensure you have proper safety gear and awareness of the immediate hazards.
