Birsay Bay (Orkney)

Birsay Bay is an exposed surfing spot on Orkney’s Atlantic coast, where wind and swell-driven conditions tend to produce consistent waves. Surfing is described as working year-round, with emphasis on winter performance when Atlantic swells reach the coast and are supported by southeasterly winds that can help keep the wind side cleaner. The bay is characterized by a mix of sand and reef influences, with the launch area described as sandy sections between rocky outcrops. Water movement is dominated by tides, and the causeway/access to the Brough of Birsay can significantly affect conditions; this includes a strong, fast-changing tide and elevated risk around stranded/covered causeway areas. Conditions are also repeatedly framed as exposed and remote. There’s no lifeguard presence, and riders are advised to come prepared for maritime winter cold and the lack of shelter at the Brough of Birsay. Local guidance highlights using tide times for planning water movement. In terms of wave outlook, the best swell window is described as west to northwest with an optimal swell height of roughly 1.0–3.0 meters. The spot is described as offering good-to-moderate wave power with peeling shapes and medium ride lengths, while very large swells can become heavy and disorganized.
