Have been to a couple of places Windsurfing and Surfing in Portugal (prior to taking up kiting). If you want a direct comparison b between Tarifa and Portugal:
Tarifa has a LOT more wind! Portugal is more beautiful and has WAY BETTER surf.
The three places I have been to is Peniche area, Ericera and Sagress area. Peniche has good surf, a lot of surfers, is only 1h from Lisbon. There is O.K night life starting at 1am . There are spots to kite, but they are average (unless wave-kiting). Ericera has very good surf. From what I have seen not ideal to kite. If you have time go down to Sagress. It is one of my favourite places in Europe. 270° of cost line. Very good surf, not too much crowds. From what I have heard there is good wind in summer –not much wind when I was there in Sept.
Lisbon is nice and night life is very good, but don't even think about going out before 11pm.
Another spot is Guincho (wave kiting)…
