  description: La Nord is Hossegor's heavy hitter—arguably Europe's most powerful beach break, where deep-water canyons funnel Atlantic swells into peaks that explode with oceanic force. This is not a wave for the timid: thick lips, heavy holddowns, and a reputation for humbling surfers who've never experienced true European power. The Landes coast's unique bathymetry creates conditions that rival reef breaks in intensity, while the shifting sandbars ensure no two sessions are identical. Autumn is prime season, when clean swells arrive and the summer crowds have departed.
