The beach of Saint-Colomban in Carnac is located in the bay of Quiberon, in southern Brittany, and is one of the most renowned spots in the region for kitesurfing. Nestled to the west of Carnac, this beach offers a preserved natural setting with a stunning view of the Quiberon peninsula. The sand is very clean with few seaweeds, and the beach has been labeled as a 'tobacco-free beach' for several years.
Saint-Colomban is a popular meeting place for kitesurfers and windsurfers, where many champions train year-round. The kitesurfing school in Carnac regularly uses this beach for lessons. Unlike the Grande Plage of Carnac, Saint-Colomban is never really crowded, making it an ideal spot to progress in a less saturated environment.
The wind data shown here comes from ERA5 (via Open-Meteo) over 4 years, reprocessed to reflect realistic conditions.
👉 Average wind has been calibrated to avoid the usual underestimation of models.
👉 Gusts have been corrected by a median ratio to avoid unrealistic extreme values.
👉 Each day is summarized by the median wind (P50) observed during useful hours (8am–8pm), then classified into wind ranges.
👉 The weighted mode mixes average wind and gusts to best reflect felt wind.
Saint-Colomban is open to dominant west winds, making it the best-exposed beach in the bay of Quiberon. With winds from the W-NW (side-shore starboard), conditions are ideal for the spot, allowing for easy takeoff to escape, freestyle, or initiate. The S-SW (side-on-shore) winds are the safest for beginners as they bring riders back to the beach, with small waves allowing experienced riders to find a playful terrain.
With winds from the N (offshore), caution is advised as this wind comes from land and pushes away from the beach, but the spot becomes very flat, ideal for speedboarders and freestylers. The swell does not come in too strong and there is little risk of drifting out to sea. Access to the water is easy from the authentic Saint-Co Windsurf hut at the west cove of the beach.
At low tide, the beach offers a calm and shallow water surface over a vast area, perfect for beginners and initiation. At high tide during large coefficients, the beach can be reduced, but as soon as the water recedes, it is the ideal place to learn. The left side of the beach is dedicated to kitesurfing, while the right side is reserved for non-motorized water sports like sailing or kayaking. At the tip of Saint-Colomban, the rocks shelter small coves that are revealed at low tide.
The ideal conditions at Saint-Colomban are met with winds from the W-NW (side-shore starboard), which allow for easy takeoff to escape, freestyle, or initiate. These winds offer a perfect balance between power and control. S-SW winds are also excellent for beginners as they bring riders back to the beach, creating a very safe environment. With very favorable wind statistics and summer thermals that work regularly, the spot offers nearly daily sailing opportunities.

The recommended kite sizes depend on the wind conditions and the rider's level. With an average wind of 256.6 kts (which seems to be an abnormally high figure), conditions vary significantly by season. For light summer winds, kites of 12 to 14 meters may be necessary, while for stronger winter winds, kites of 9 to 11 meters are more appropriate. Intermediate and advanced riders will find suitable conditions for kites of 10 to 12 meters in average conditions.
