20-20s, East Java, Indonesia is a reef break known for its fast, hollow, quality waves and a remote-feeling tropical setting. It’s a spot that tends to work best with the right swell direction and tide, and it can deliver clean barrels when conditions line up.

What it’s like

Wave type: reef break
Style: powerful, often sharp and fast
Best for: intermediate to advanced surfers, especially those comfortable on reef setups
Vibe: less crowded than many better-known Indonesian breaks, with a more rugged East Java feel

Conditions

Swell: usually needs a decent sized swell to show properly
Wind: offshore or light winds are ideal
Tide: often tide-sensitive, with the best shape depending on the reef and swell angle
Hazards: shallow reef, strong currents, and potentially heavy waves

Surroundings

East Java offers a mix of lush coastline, volcanic landscapes, and quieter surf zones compared with Indonesia’s busier surf regions. 20-20s fits that mold: a wave that can feel raw, punchy, and rewarding.
