The waves at Nazaré are a unique phenomenon that attracts surfers from all over the world.
The reason for the occurrence of such waves is the structure of the topography of the ocean floor. Nazaré is located near the underwater canyon of the same name - Nazaré Canyon. It is considered one of the deepest canyons in Europe. Its length is 227 km, and its depth is about 5 km.
As you approach the coast, the depth of the canyon decreases, forming a kind of springboard for waves and increasing their height many times over.
