Calshot is one of the South Coast’s premier winging and windsurfing locations, situated at the entrance to Southampton Water.
This historic spit of shingle offers a unique dual environment: to the west, you have the relatively sheltered waters of Southampton Water, and to the east, the open waters of the Solent. This makes Calshot a highly versatile spot that can handle almost any wind direction. The local community is large and very supportive, often based around the Calshot Activities Centre. For wingers, the main advantage is the availability of flat-water reaches inside the spit and the more challenging rolling chop in the Solent reaches. The spit itself helps to flatten the water in South-Westerly winds, making it a favorite for speed and maneuvers. Ideal Conditions: SW, S, SE, W, NW. South-Westerly is side-shore and provides the cleanest conditions.
SW, W, S (Prevailing SW is best for side-shore)
15-25 knots is the sweet spot for most; 4-5m wings in lighter air, switching to 3m wings when it exceeds 28 knots.
Best at High Tide (+/- 2 hrs) to avoid the strongest currents and to ensure enough water depth over the shingle bank.
