Praia do Abano
It's a common misconception to think that the north side of Guincho Beach is actually Abano Beach. It's not. To get to Abano Beach you'll have to drive (or walk) 300 meters from the north side of Guincho, all the way until you find a restaurant and a small bay.
This spot can be quite fickle, often without much sand on the bottom, turning the waves into just shore breaks. But it's always worth checking it out since when the sand settles back in it can offer some very fun waves, often uncrowded. Just like Guincho, the best swell direction is SouthWest, South/SouthWest, South, SouthEast, Easterly, and Southerly Winds but it doesn't hold as much swell.
