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)
- Very consistent reef-coral break with fast, ledgey left-hand waves when conditions connect.
- Offshore trade winds during the dry season help produce cleaner surf conditions.
- Often described as fun and more approachable than the heavier main G-Land peaks.
- Reef and sharp coral with sea urchins; danger increases at very low tide.
- Rip currents can be present near the reef edge on larger swells.
- No on-site rescue/lifeguard services reported; emergency help is regional.
