About this spot

About

Santos Bay (Hachijojima) is an exposed reef break on the volcanic island of Hachijojima in the Izu Islands. Surf is described as reasonably consistent, and the spot is especially known for fast, long right-handers when conditions line up. Water quality is characterized as excellent and very clear. The main challenge is the access: the entry/launch area involves sharp volcanic rock and reef heads, and it is reported as very difficult. Strong tidal currents are also common around the island’s points, and the reef can become dangerously shallow at low tide—so planning around tides and your approach is critical. Wind-wise, the best experience is associated with west to west-northwest flow (with West winds described as offshore and producing clean, groomed faces). For swell, the spot is best when southeast through south to southwest swells are present, with working swell height reported around 1.0–2.5 meters. Wind reliability is noted as low, and volcanic cliffs can create wind-shadow effects depending on direction. It’s a low-profile destination because of the remote location and limited access, with the surf community described as having some local expectations—so following lineup etiquette matters. On-island medical care is available via Hachijo Hospital, while on-beach rescue/lifeguards are not provided; bring appropriate protective gear (especially surf boots) and do not rely on rescue services.

  • Long, fast right-hand reef waves
  • Best wind: west–west-northwest for cleaner faces
  • Rocky entry with sharp volcanic hazards (booties strongly recommended)
