Siouville is Normandy's hidden gem—a quality reef break on the Cotentin Peninsula that produces powerful, hollow waves when Atlantic swells wrap into the English Channel. The wave is significantly better than most people expect from Normandy, with genuine barrel potential and consistent form. The water is cold, the reef is sharp, and the region's D-Day history adds gravitas to surf sessions. For surfers exploring northern France beyond the famous southwest coast, Siouville is the revelation.

Siouville is a reef break in Siouville-Hague, Normandy, France, with peaks that run both left and right.
Siouville picks up swell from the W round to the NNW, and it's best when it's coming straight out of the WNW. It starts working at around 1m and handles up to about 3.5m, with the sweet spot around 2.1 to 2.9m. Period matters too: aim for 14s or longer, as anything under 11s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.
An E wind is dead offshore at Siouville, and anything from the ENE round to the SE keeps it clean. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.
Siouville is at its best around the mid to high tide, roughly 0.8m to 2.5m on the local chart. Below 0.3m it gets dangerously shallow.
The most reliable run of swell at Siouville comes Sep to Jan. There's a second window in Mar to Apr too. Autumn/winter swells. Normandy's most consistent spot.
The water at Siouville averages around 12°C, so you'll want a 5/4mm with boots. It shifts a few degrees through the year, so check the season before you pack.
