Surfing Siouville: The Complete Guide

Siouville is a reef break located in Siouville-Hague, Normandy, France, offering both lefts and rights along the North Atlantic's seasonal swells. 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. Rated as advanced difficulty with moderately crowded conditions, this reef break is a worthy destination for surfers looking beyond the usual suspects.

Best Conditions

Swell Direction: The ideal swell direction is WNW (290°), with workable conditions from W to NNW (260°–330°). Swells outside this window will either miss the break or produce disorganized waves.

Swell Size: Siouville needs a minimum of 1m / 3ft to start working and handles swells up to 3.5m / 11ft before conditions deteriorate.

Swell Period: Look for a swell period of at least 11 seconds, with 14 seconds being the sweet spot. Longer periods deliver more organized, powerful waves with better shape.

Wind: True offshore here blows from the E (100°). The full offshore range spans ENE to SE (60°–140°). Glassy conditions under 4km/h from any direction also produce excellent surf. Plan for sessions throughout the day.

Tide: This spot works best at mid to high tide. Optimal tide range is 0.8m–2.5m. Avoid surfing when the tide drops below 0.3m — it becomes dangerously shallow.

When to Go

Primary Season: The prime window at Siouville runs September, October, November, December, January (Sep–Jan). This is when swell consistency and direction align most reliably with the break.

Secondary Season: A secondary window opens March, April (Mar–Apr). While not as consistent, patient surfers can still score quality sessions during this period.

Season Notes: Autumn/winter swells. Normandy's most consistent spot.

Water Temperature: Expect water temperatures around 12°C / 54°F. A 4/3mm or 5/4mm wetsuit is essential, with boots and gloves for extended sessions.
