Long beach stretches from the gap of native coastal shrubs (between Navegantes and Gravata) to the northern end (about 6kms). The norhtern end features and island which at its right side has a good long peeling lefthander which can produce very long rides when conditions are good. The small bay between the island and the cliffs is offshore to NE winds but the water is polluted. Be ready for the odd turdie fellow swimming towards you!
Following south there are several banks that can offer good waves and just past the rock outcrops there's a left pointbreak called "pedrinha" which is a sand/rock bottom combo and from there are several banks that go along the beach southwards to navegantes.
Overview
Atmosphere
It's a perfect place to learn to surf. Don't expect hollow sections, take offs are usually mellow and so the sections are. Sometimes can be a bit heavy when there is some big sweel. And the paddle out can be tough as there's no channels to help getting to the lineup. The lefhander next to the island can hold solid 6-8ft waves.
General
Over the summer months this place is way too crowded. I myself used to hit the water at 6:30am with a couple of mates and surf til about 8am then when would see hords of people with all sorts of boards paddling in. From that time onwards is just impossible to get a wave without being dropped in.
