Periscopes

East Sumbawa, Indonesia
🌀Strong rips🪸Sharp reef

Periscopes is a long, rippable right reef break in East Sumbawa that produces tight barrels over a safe reef platform. The wave works best at high tide and provides a quality alternative to Lakey Peak, offering longer rides with good barrel and turn sections. Its exposure to dry season SE trade winds can cause afternoon blow-out, making morning sessions essential for clean conditions.
