Agreed with the above,
Portugal area around Peniche and Ericeira works a treat around September/October. Ericeira in particular offers a variety of surf breaks which are all relatively close to each other, and never disappoint in terms of waves consistency in those months. You can find brakes from beginners to pro's, though many of these are reef brakes, so make sure you ask around before paddling out, i.e. don't go for Coxos unless you know what you're doing

Be prepared for crowds in Ericeira. Peniche can be a bit more forgiving on a smaller day, and tends to be less crowded as a beach break, and if you're lucky you can get tubes ++ at Supertubos.
