Surf: Excellent quality rivermouth left only breaks on the biggest swells of the year. It’s fast, hollow and shallow and doesn't hold above about 8 ft. Low tide only. Environment: Crowded when on. Foz has an active surfing population, plus the beaches and carparks get packed in summer. Good beach facilities, shops and bars with campsites fairly nearby. Some estuarine pollution from the Ria Foz.
