According to Windsurf Magazine:
Stokes Bay is :Probably the safest place to sail on this stretch of coast and suitable for beginners. The ideal wind direction for Stoke Bay are SW and SE which produce the cleanest wind but can also be sailed in anything from E to WNW. The tidal range is small, the most furthest you have to walk to the water is 10 metres and launching is easy even in very strong winds. It’s a very good place to practice short board technique. In an E just about every windsurfer in the area sails here as the wind funnels between the Isle of Wight and the mainland.
A speed limit of 10 knots is applicable within half a mile of the Solent shoreline at Stokes Bay and Lee-on-the-Solent.
