About
Treasure Island is a remote right-hand reef break in the Banyak Islands known for long, powerful rides with multiple barrel sections. Reports commonly describe peeling wall sections that can run for roughly 200–350 meters, with some accounts suggesting up to around 400 meters across several parts of the wave. Wave quality is consistently described as excellent or even world-class when conditions line up. Surf works across all tides, with optimal swell described as coming from the south to southwest (roughly 1.0–3.7 m across sources). Offshore southwest winds are favored for clean, hollow faces, and the wave is also described as being more sheltered from prevailing southerly winds than many other local options—helping it stay more reliable when winds would blow out other breaks. The main hazards are reef/rock contact and the fact that the end section can become extremely shallow, particularly at low tide—this is emphasized as a key safety warning when swell is large. Currents can also become strong during larger swells, and the lineup is typically remote and accessed by boat, with limited rescue availability. Seasonally, the dry period is the most consistent window, with July specifically highlighted as the best month. Water temperatures are warm year-round (about 28–30°C), and wetsuit needs are typically minimal (rashguard or very light protection; booties are commonly recommended due to shallow reef sections).
- Long right-hand reef with multiple barrel sections and rides often 200–350+ meters
- Offshore southwest wind can improve face quality
- Dry-season reliability with July highlighted
- Long right-hand reef break with multiple barrel sections and very long rides (often several hundred meters).
- Clear water and generally high wave quality, especially when offshore wind grooms the face.
- Dry-season window (May–September, with July highlighted) aligns with more consistent conditions.
- Remote reef with rocks and coral; the reef end can get extremely shallow at low tide—extra caution on larger swells.
- Access is typically boat-based and rescue/medical support is limited and far away.
