When to surf · Lisbon and Cascais
Cascais in May
Late spring. Smaller, cleaner conditions and water finally past the winter low. One of the best-value months: warm enough, uncrowded, and the schools are not yet at summer capacity.

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.
