This beach is about twenty minutes to thirty minutes away from the center of Lisbon. Usually waves of about 1m to 2 m high. The Estoril coast is very similar to Laguna Beach. Many small beaches for 25KM with many different waves. The best one is S o Pedro do Estoril.
Conditions are better at high tide, and certain parts of the beach are better than others.
South of Lisbon across the river near the Caparica Coast. Lisbon Area S. Pedro , has an excellent shore break, but is only rideable at high tide. Unfortunately the beach is very small, and the beach is often very crowded which makes skimming difficult. Tamariz , is one of the only beaches that is rideable during low and high tide, waves tend to break far from the shore, so they are only surfable with very good quality foam boards, of which there are more and more now days. Monte Estoril is good at high tide and when there are big swells.
