Itamambuca

Ubatuba's marquee break, a sand-bottom beach at the north end of the bay fed by the Rio Itamambuca. A sandbank at the river mouth on the north corner shapes the best, fastest waves — predominantly rights, with lefts available on the outer banks — and the beach is fairly consistent, working through all tides. It fires on S/SE groundswells with NW/W offshores, hosts regional and national contests, and was designated Brazil's National Surf Reserve.
