The Pororoca is the longest wave on the planet. It holds the Guinness world record for longest surf ever: 12.5 kilometers over 37 minutes.
“The wave has become popular with surfers. Since 1999, an annual championship has been held in São Domingos do Capim. However, surfing the Pororoca is especially dangerous, as the water contains a significant amount of debris from the shores of the river (often entire trees), in addition to dangerous fauna. In 2003 the Brazilian Picuruta Salazar won the event with a record ride of 12.5 kilometers during 37 minutes.
Along the branches or “caños” in the Orinoco Delta, pororoca is known as macareo, which is also the name of one of these branches.”
