When to surf · Lisbon and Cascais
Cascais in July
Peak summer. Smallest surf of the year, warmest water, busiest beaches, and the nortada blowing hard by early afternoon most days. Surf at dawn, learn on the sheltered bays, or go to the Algarve. Camps are fully booked.

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.
