YouTubeWatch on YouTube CustomizeCustomize this spot

Itamambuca is one of Ubatuba's premier waves and a regular competition venue on the Brazilian surf circuit. The rivermouth creates constantly shifting sandbars that produce powerful peaks with both lefts and rights. The beach can pick up swell from almost any direction, making it one of the most versatile spots on the São Paulo coast. The surrounding area is lush and tropical, with the river providing a natural boundary that keeps the vibe more relaxed than some of Brazil's more famous breaks.

Frequently Asked Questions

What tide is best at Itamambuca?

The Itamambuca profile does not specify a preferred tide stage. That does not mean tide has no effect: check local conditions alongside swell and wind.

What wind direction is offshore at Itamambuca?

The Itamambuca profile uses wind from NW (315°) as its preferred direction, with an offshore range of 270° to 45°. Wind speed matters too: light winds outside that range can still produce surfable conditions, while strong offshore winds can make takeoffs difficult.

What swell size and direction work best at Itamambuca?

The Itamambuca scoring profile favors swell from SE (95° to 170°), a swell-height range of 0.9m to 2.5m, and a reference period of 12s. These are model inputs, not guaranteed breaking-wave heights or a promise that the surf will suit every ability.
