Grumari surf FAQ

Is Grumari good for beginners?+

Grumari is a beach break over sand, 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. Set the level to Beginner above and WaveCheck flags the smaller, cleaner hours worth paddling out for.

What's the best board for Grumari?+

Different days call for different boards. Grumari can get sizeable, so a shortboard comes into its own on bigger days, while a longboard still works when it drops small. Tap through the boards above to see the live score for whatever you'll be riding.
