Surfing Guethary: The Complete Guide

Guethary is a reef break located in Pays Basque, France, offering a right-hander along the North Atlantic's seasonal swells. Guéthary is the Basque Country's big-wave playground—a powerful right-hand reef that comes alive when larger swells shut down the surrounding beach breaks. 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 NW (305°), with workable conditions from W to NNW (280°–340°). Swells outside this window will either miss the break or produce disorganized waves.

Swell Size: Guethary 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 10 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 ESE (120°). The full offshore range spans E to SSE (90°–160°). Glassy conditions under 4km/h from any direction also produce excellent surf. Plan for early morning dawn patrol sessions.

Tide: This spot works best at mid to high tide. Optimal tide range is 0.5m–1.8m.

When to Go

Primary Season: The prime window at Guethary runs October, November, December, January, February, March (Oct–Mar). This is when swell consistency and direction align most reliably with the break.

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

Season Notes: Big swell magnet. Works when other spots maxed out.

Water Temperature: Expect water temperatures around 16°C / 61°F. Bring a 3/2mm wetsuit — 4/3mm in winter months.
