Cave Surf Spot Guide, Portugal

Nestled in the heart of Ericeira's World Surfing Reserve, Cave delivers one of Portugal's most intimidating right-hand reef waves, breaking over flat rocks into hollow, fast and powerful sections that demand absolute precision. This ledgey beast sucks water from below the surface, forming tubular pits that have only recently earned a reputation among the bold, offering a raw, adrenaline-charged session unlike anywhere else on the coast. It's the kind of spot that rewards pros with heart-pounding rides but punishes any hesitation.

Geography and Nature

Cave sits on the southern flank of Dois Irmãos Bay, a short 10-minute walk from the northern slope of Ribeira d'Ilhas in Ericeira, part of Portugal's central Atlantic coastline. The area features a rugged, rocky shoreline wedged between sheer cliffs and looming mountains, with the wave breaking over a shallow reef plate that doesn't connect directly to land, creating an exposed and remote feel despite its proximity to town. Praia da Pesqueira lies nearby to the south, showcasing the heavy, reef-dominated landscape typical of northern Ericeira.

Surf Setup

Cave is a classic reef break firing fast rights over flat rocks, known for its hollow, powerful and ledgey shape that often doubles up into tubular sections reminiscent of a mini Shipsterns. It thrives on north to northwest swells, with east to northeast winds providing clean offshore conditions, and performs best at mid to high tide when the reef is covered enough to avoid the shallowest dangers. On a typical firing day, expect 1 to 2.5 meter waves marching in with intense suction below the lip, delivering 30 to 70 meter rides that require starting deep and threading precision lines through the pits.

Consistency and Best Time

Cave offers inconsistent surf that breaks only sometimes, with summer months from June to September often flat due to small swells, making it unreliable then. The prime window runs from October to March, when northwest groundswells pump in during winter storms, peaking in January and February for the heaviest sessions; avoid midsummer entirely and check forecasts closely as even peak season can go quiet. Early mornings or weekdays boost your odds of clean lines when conditions align.

Crowd Levels

Cave remains very rarely crowded, staying mostly empty on both weekdays and weekends thanks to its remote access and heavy nature. You'll share waves sparingly with a mix of local and visiting advanced surfers.

Who It's For

Cave is strictly for pros or kamikaze surfers who can handle powerful, shallow reef waves with technical control and comfort in 4-meter faces. Beginners and intermediates should steer clear due to the speed, ledges and lack of forgiving sections, while advanced riders will find world-class barrels and maneuvers on offer. Even experts are wise to wear protections for the high-risk setup.

Hazards to Respect

Watch for flat rocks on the shallow reef, strong rips pulling offshore and sea urchins lurking below. Approach with local knowledge and respect the power to stay safe.

Water Temperature and Wetsuit Guide

Summer from June to October sees water temperatures around 16 to 20°C, where a 3/2mm spring suit or shorty with optional booties works well for comfort. Winter from December to March drops to 13 to 15°C, calling for a full 5/4/3mm wetsuit, hood, boots and gloves on bigger days. Spring and fall hover at 14 to 18°C, suiting a 4/3mm wetsuit with booties for most sessions.

How to Get There

Fly into Lisbon Airport (LIS), just 34 kilometers south, then drive north on the A8 highway for about 30 minutes to Ericeira; the second nearest is Badajoz Airport (BJZ) in Spain at 225 kilometers east. From Ericeira town center, head north past Coxos to Praia da Pesqueira, then walk 10 minutes south along the coastal path to Dois Irmãos Bay for Cave access. Street parking is limited but available nearby on the cliffs; no reliable public transport reaches the spot directly, so a car or scooter is ideal, with the reef visible from the trailhead.
