Wind Days = % of days with 12–35 knot average wind speed (ideal kiting conditions). Based on 4 years of historical weather data.
Partially sheltered coastline with moderate, varied conditions
Goas Treiz is located in Brittany's Rias system, a drowned river valley creating a sheltered bay environment. The spot features a northwest-facing coastline with shallow water typical of French Atlantic estuarine systems. The bay's protected waters limit wave exposure, with average heights around 1m, making it suitable for progression rather than wave-focused riding. Wind reliability is modest at 29%, requiring patience for suitable conditions. The northeast (45°) wind direction provides reliable side-shore access for the bay's orientation. Water temperature averages 13°C, requiring thermal protection year-round. Shallow bay waters with mudflats and variable depths demand careful navigation and local knowledge. The narrow bay entrance and river current system create dynamic tidal conditions. This spot suits beginners and intermediate kiters seeking protected waters with manageable wind and wave conditions. The location is ideal for flat-water freestyle practice and light-wind development rather than wave riding.
