About this spot

About

Ndana is an exposed reef break with consistently good waves, featuring hollow, fast, and steep left-hand sections over sharp coral/reef and rocks. The spot is reported to be regular in frequency and best suited to surfers who already handle demanding reef conditions. Conditions are strongly shaped by access and environment. The only way to reach the break is by boat, and the island setting means there is no on-site support for launching or safety response. Sources emphasize hazards such as reef edges, shallow areas over reef, and remote location factors, and they also note the possibility of sharks. The wave window described for Ndana starts working around roughly 1.0–1.5 m and can hold up to about 2.5 m+ (with hollow sections that can become very heavy on bigger days). A left-hand take is the dominant direction, and the reported working swell comes from the south/southwest sector. Mid tide is cited as the best tide position. Wind is trade-wind dominated during the dry season, with the northeast direction identified as the best wind direction and with reported clean/less-blown proportions (53% clean / 27% blown during the season). Visitors should plan around the May-to-September/October dry-season consistency and prioritize safety planning: notify the local military base before arrival (passport may be required) and carry appropriate emergency readiness because medical access is distant.

  • Consistent exposed reef left-hand
  • Hollow, fast, powerful wave shape
  • Dry-season trade winds can be favorable (northeast offshore for the main left)
