Perhaps more of a surf spot than a windsurf spot but some days it works pretty well. Best on a not-too-big swell and especially worth a look in easterly winds. Winds with west in can be gusty as the wind comes over the small island which seperates Santa Tomas from Binigaus. The bar overlooking the beach - open during the summer months - is a nice place to relax between sessions.
Pass through Es Migjorn, which is about 3km from Sant Tomás. There is free parking on the right at the bottom of the hill.
Pretty safe although powerful rips on bigger days and the waves are often very closely spaced. The beach is sandy with slabs of reef once in the water.
