Carcavelos in October
Prime autumn and the heart of contest season: the WSL Championship Tour at Supertubos in Peniche and the Challenger Series at Ribeira d'Ilhas in Ericeira both run this month. Solid swell, manageable crowds, water still wearable in a 3/2 early on.

Carcavelos
Carcavelos is best October to March, when swell reaches the bay and mornings can be clean before the wind. Summer is small and blown out by the afternoon nortada, so it is a dawn-only wave then. The Capítulo Perfeito tube contest waits on a swell somewhere between January and March.

CarcavelosCarcavelos
Lisbon's home beach and the busiest wave in Portugal on a good day. A wide, forgiving beach break one stop from the city on the Cascais train line, with a fort at one end and peaks spread along the sand.
All levelsAutumn to springParede
A right-hand rock reef on the Cascais train line that sleeps most of the year and wakes up on a big west or south-west swell. A local's wave for experienced surfers, not a learner's beach.
