About this spot

About

20-20s is a smaller reef-coral break in Grajagan Bay (G-Land) that works best on easterly swell at mid-tide. The wave is primarily a left-hand reef break, and sources also note that the right can break under ideal conditions. Sessions are described as fast and ledgey, with peeling lines that can become faster and more powerful as swell increases. In terms of water and hazards, the bottom is reef with sharp coral plus rocks and sea urchins. Rip currents are also reported, particularly near the reef edge on larger swells. Because the reef can become very shallow at dead low, multiple notes warn to avoid riding at low tide and to watch for urchin packs during those times. Wind is generally favorable during the dry season, with east to south-east offshore trade winds producing cleaner conditions for surfing. Wind seasonality is reported most strongly from April through October in one dataset, and another dataset highlights May through September as a favorable window, with higher reliability during the dry months. Access is camp-centered and practical: the spot is commonly reached by staying in a G-Land surf camp and walking south along the beach (often described around 15–30 minutes, or about 30 minutes), or by boat from Grajagan village. Park rules apply (including national park entry fees), and rescue is not reported as available on-site, so self-rescue and coordination with the surf community/camps are important.

  • Fast, ledgey left-hand reef break with consistent performance
  • Offshore trade-wind pattern during the dry season helps create cleaner surf
  • Short-to-long rides (about 50m typically, up to ~150m on bigger days)
