A capital city with Atlantic surf beaches forty minutes away by train, and the Arrábida coast south of the river where the water is calm and turquoise and almost nobody outside Portugal knows about it
Expecting warm water. This is the Atlantic at the latitude of Washington DC but cooled by upwelling — 18–19°C in August is normal, and it is a genuine shock.
July and August in the city, every summer weekend at Costa da Caparica, and Santo António on 12–13 June
Cascais and the Arrábida coves are calm and easy. The Guincho and Caparica surf beaches have strong rips and are not for small children.
Cascais gives you the train into Lisbon and the coast on your doorstep. Setúbal, across the bridge, is cheaper, has the Arrábida beaches and the better seafood, and almost no international visitors.
0 is this destination’s own quietest month and 100 its busiest. The scale never compares one destination to another. Source: Wikipedia — Cascais
