Brazilian surfer and disputed world record holder of the longest wave ever surfed (11 kilometers 800 meters), Serginho Laus, talks about surfing the longest wave in the world, the pororoca of the Amazon River in Brazil.
The pororoca is a wave but it is scientifically called a tidal bore. A tidal bore is a fancy way of stating an incoming ocean’s tide meeting the flows of an outgoing river. The pororoca forms when particularly large high tides from the Atlantic Ocean start rolling up the Amazon River. The pororoca can get as big as 12 feet and travel as far as eight miles. The pororoca is largest in February and March.
Surfing the pororoca can be very dangerous. The water contains massive amounts of debris (trees, rocks, etc.) and contains numerous harmful animals (piranhas, anacondas and the candiru).
