Heh, Świnoujście is rather far from Hel, probably more than 200km. You'd better take the ferry to Gdansk or Gdynia, and from there you've got more or less 50km, or (I hope) there'll be direct ship connection from Gdansk to the Hel peninsula.
You've asked whether Hel is good - I'll tell you that it's one of the best kitesurfing spots in Europe, however you'll have to take a wetsuit. We're not as hot as Egypt is.
If you dont mind swimming in sea, all wind directions will be good. Check yourself:

Hel peninsula has the beginning in Wladyslawowo and ends in Hel
