This is a spot that needs a HUUUUGE East swell to wake up. If PG or Prainha are like 10ft high, you'll find 5-6ft at Sumidouro. This wave is like a Pororoca wave: very, very, very long in the biggest days. Because of the flat bottom, waves start to break very far from the beach. Lonboard guys like to position themselves like 1km far from the beach. In the biggest days, waves connect through several section, make it a real long wave. As they march towards the beach, they became higher and permit more maneuvering in the critical part of the wave. And, finnally, when the wave gets in the inside section, you have to put all your power to speed your board and try to make the barrel. It is a fantastic wave. There are only two problems: it is very rare (less then 5 days per years), but when it pumps all the São Francisco do Sul Island surfers are there.
