Surf: Going from west to east there are several rivers that produce the pororoca, including the Cassipore, Araguari, Macapa Canal do Norte, Guajara, Moju, Marajo island, Guama/Capim and Pindaré/Mearim. The Rio Araguari was the biggest and longest bore wave in the Amazon, on the largest river of Amapa state, its source being high in the western Tumucumaque mountain range about 350km away. Unfortunately, because of river dams upstream and extensive buffalo breeding creating tributaries which lower the water levels, the Araguari river bore has been downgraded from 5 star to 1star. A recent discovery of a new bore wave in the Bailique Islands means that hiring a boat out of Macapa and surfing the mouth of the Amazon is still possible with the right guide. Environment: Araguari was the only river in the world to start breaking out at sea and this is where the Red Bull expedition took place in April, 2003 and on May18, 2007, 12ft (4m) sections were ridden. Cutias is the remote village where most expeditions start, and there are no “normal” ocean waves in the region.
