It is a phenomenum that occurs in the winter, from January to May in the northern hemisphere. It is the encounter of the waters of the river and the sea that form a tumultuous wave when the tide ebbs, when the tide rises, producing a very loud noise.
It is very much feared by the Riverside folk, because the wave turns the boats over and beats the scullers against the trees and banks breaking them to pieces. In the winter the people are afraid of leaving their communities and the boats are removed from the water, because they cannot even stay on the river bank, so the ’pororoca’ can’t reach them.
However, the phenomenum attracts many tourists to the region and some risk their lives surfing on these waves. ⠀
