Quatro Ribeiras Bay (Azores)

Quatro Ribeiras Bay is a reef break on the north coast of Terceira Island, best known for producing both left and right waves from a volcanic reef bottom. The surf is most dependable around mid tide, with the wave setting described as working regularly and delivering normal ride lengths commonly in the 50–150 m range. The main challenge is the shore and takeoff: access is described as difficult and more complicated than a simple sandy entry, with surfers needing to climb over large rocks. Hazards around the bay include rocks and reef outcrops, sharp volcanic rock, and submerged reef (with coral noted in hazard descriptions), so reef awareness and careful entry planning are essential. On the right swell and conditions, the break is associated with better run times—better days can extend rides beyond the normal range, and the spot is described as capable of holding significant size. Wind descriptions point to frontal/gradient patterns, with southerly wind directions discussed as part of a favorable setup when aligned with a north swell. For planning, the area also features nearby natural volcanic pools that can provide a calmer option for swimming, entry, or exit if the shore break is heavy. Visibility is frequently described as very clear, and conditions remain a rugged, low-crowd experience, with weekday sessions often empty and weekends typically seeing only a few surfers.
