Grumari
Grumari is Rio de Janeiro's most pristine surf beach, an environmental reserve where big wave legend Carlos Burle has called his favorite local spot. The beach is protected from development, creating a natural sanctuary just an hour from the city center. The waves are versatile, handling various swell directions and producing both lefts and rights along the beach. Access is controlled and parking limited, which keeps the crowds manageable even on good days.

Frequently Asked Questions
What kind of wave is Grumari?
Grumari is a beach break in Rio de Janeiro, RJ, Brazil, with peaks that run both left and right.
What swell works best at Grumari?
Grumari picks up swell from the SE round to the SW, and it's best when it's coming straight out of the S. It starts working at around 0.9m and handles up to about 2.5m, with the sweet spot around 1.6 to 2.1m. Period matters too: aim for 14s or longer, as anything under 10s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.
What wind is offshore at Grumari?
A NW wind is dead offshore at Grumari, and anything from the W round to the NE keeps it clean. The morning is typically the best window, roughly 5am to 10am. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.

Grumari isn't especially fussy about tide and generally works through the cycle, so swell and wind matter more here. Big tides can still change how it breaks, so it's worth checking before you paddle out.
