Another spot in the south of Portugal in the Algarve ... a flat water spot for fans of windsurf slalom and windfoil.
With incredible wind statistics (15 to 25 knts every day in summer), this is the PLACE for the holidays 
Located 30 kms from Martinhal, the wind is a little less strong there (-5knts approximately), still off-shore, but still less gusty as soon as you move away from the beach (even if it remains a wind earthen).
The bay between Portimao and Lagos is about 10 km long ... so there is something to do there ;-)
A little video demonstration:
