About this spot

About

Mother Iveys (Spot M) is a powerful, hollow beach break on the North Cornwall coast near St. Merryn, best known among experienced surfers. The wave can be fast and heavy, offering short, punchy rides that commonly stay under about 50 meters. The spot is described as sheltered to semi-sheltered, with local headlands helping shape how waves arrive. For surf performance, sources consistently point to a west / south-west offshore setup as ideal for grooming. The break is reported to start working around 1.0–1.5 m and can hold up to 3 m+ (and can handle larger swells wrapping around Trevose Head). However, it’s also described as more sensitive and technically demanding than nearby areas, and wave behavior becomes hazardous when swell meets rocks—especially as conditions rise toward high tide. Safety is a central concern at this location. Multiple warnings cite rip currents and undertow, along with rocks and hidden reef/submerged hazards near the ends of the bay. Additional guidance emphasizes that the wave often changes quickly at high tide, becoming dangerous as it pushes up against rocks. Local etiquette matters too: the lineup is noted as having moderate localism and sensitivity to crowding. Seasonally, January is identified as a best month in spot summaries, while another source indicates autumn and winter offer the most consistent swells and offshore winds. Water temperatures are cold year-round (roughly 8–10°C in winter into the high teens in late summer), so wetsuits are essential—typically winter thicknesses with boots, gloves, and hood in the colder months. The spot itself is accessed via steep coast-path/walking routes and has limited/no on-site facilities.

  • Hollow, fast, powerful waves (often described as a regional classic)
  • Starts around 1.0–1.5 m and can hold to 3 m+
  • Offshore west/southwest winds groom the face
  • Critical hazard zones: rocks, submerged reef, and rip currents/undertow
