When to surf · Lisbon and Cascais
Cascais in September
The month a lot of people rate as the best of the year. Consistent swell returns, the water is still warm, the wind drops and the crowds thin. Everything the coast does well lines up at once.

Cascais
For the Cascais town beaches, only a big winter swell wakes them up. Guincho surfs best autumn to spring; through summer it belongs to the wind and kite crowd on the afternoon nortada. Beginners are better off taking the train out to Carcavelos or Caparica in any season.
