As Halloween crept up at the toe-end of October, so did a monsterous swell along Portugal's Costa de Prata. That means only one thing — Nazaré is ready to fire. And fire it did, with the second massive swell of the season enough to send more shockwaves of fear than any Halloween costume or horror film. Plenty of surfers reckon this is the scariest wave on Earth, and it's not hard to see why. Sit back and enjoy the carnage in this extremely well-produced video straight from the firing line.
