On the coast between A Coruņa and Setubal the winds are often between N and W. So seek protection on N sides of the rias and estuaries. Summer is often balmy but other times of the year it can get real rough there.
Further down on the Algarve, winds may vary, become light, at times will sync with whatever is going on in el Estrecho (the Gibraltar). You will want a nook where you are protected from more than one side. Summers are often balmy and winters bring periods of heavy rain driven onshore by fronts and lows that pass by.
close to fishing
harbours in Spain
- them heavy fishing
boats make no exceptions for anchored boats - you do not want to get tossed out of your bunk, especially at 05:00 local time. ;-)
If you have your mind set on going, nothing can stop you. No worries.
