Cape Northumberland surf FAQ

Is Cape Northumberland good for beginners?+

Cape Northumberland is a reef break over coral, usually breaking in the 0.5–2.5m range, and how suitable it is for beginners really depends on the size and power on the day — not a fixed label. The coral bottom rewards some confidence in the water and awareness of what's beneath you, especially as the size picks up. Set the level to Beginner above and WaveCheck flags the smaller, cleaner hours worth paddling out for.
