Surf: Arari (the capital of watermelon!) is a 3h drive away and offers the cleanest bore conditions thanks to better weather and a narrower river. The Rio Mearim breaks in as many as 12 sections in a 1h30min journey from the rivermouth mudbank known as Cement Mix to the Arari village. The wave can range in size from a 8ft (2.5m) wall of whitewater to a tiny but superclean 1 to 2ft right. Auera Auara ! Environment: Over a period of 5 days, surfing can be had early morning from between 5-8am to 7-10am.
