Saint-Cast-le-Guildo

The wind often blows from the west to northwest, which gives a side-shore to side-on component depending on the exact orientation of the wind and the access point. Launching is done from the main beach; at low tide, the usable area widens significantly, allowing for safe take-off and landing. The depth is gradual with a mainly sandy bottom, but banks and local bottom changes may appear depending on the tides.

The main navigation area is located in front of the central beach; it is preferable to avoid the northern area near the rocks and the edges of the boat access channel. Local schools set up their take-off/landing zones near the parking lots and access paths to limit crossings of bathers. In strong wind and swell, the area close to the shore can form surfable sections, while in small swell the water surface can remain choppy until mid-tide.

Be cautious of high tides that reduce the available beach and bring the navigation area closer to coastal obstacles. Currents strengthen near the passes and the entry channel; in case of land wind (east/local), conditions can become onshore and more dangerous for kitesurfing.
