In summertime you have to be lucky ........ sometimes enough wind and sometime ...... bullshit .....
but the windchances are better compare to manny spots in the south of Europe....
dont forget a wetsuit ....
The whole westcoast is ok ..... but very crowdy ......
Zeeland has some very large beaches (Vrouwenpolder, Brouwersdam, Neeltje Jans) and its possible to kite with various winddirections ....
the sea mussels are delicious with french friets and a big beer ....
