A small, friendly marina with easy access in all weather and conveniently located between Lisbon and Cape St Vincent. I arrived in mid-September and left my boat (10m x 3.6m) here for the winter 2019: <1000 euro for 6 months, with cheap extensions possible (less than half the price of anywhere on the Algarve coast (Albufeira, Portimao...)). The helpful harbour office is open until late 7 days a week; everyone speaks English and sometimes French. The showers are fine, and there is a launderette for boat owners (get tokens from the office). The outer commercial harbour is wide open to the SW, but storms from that direction are rare. The marina is behind a very large (oversized?) wall so it is well protected from that direction, but I supect the mooring lines will work hard when big winter winds come from the N/NW. Beware: the marina is tiny, half filled with small fishing boats. Only 3 pontoons for yachts up to 12m plus a few places for larger boats, including 1 or 2 catamarans. So if you want a long-term space, you must phone ahead (I think I got the very last berth!).
If the marina is full, there is lots of free anchoring space over sand in front of the castle near the lovely beach - open to the SW, but fine in good weather. The town lacks interest and is an upward trek (there is a public elevator along the seafront visible from the marina). Only a couple of small supermarkets, not cheap, and all fresh vegtables and fruit are curiously horrible. Cheap buses to Lisbon, etc.
