Baleal is a rocky islet just north of Peniche, joined to the mainland by a narrow sand spit with a beach on either side. That layout is its great advantage: whichever way the wind and swell come from, one side is sheltered. It is the surf school capital of Portugal, with camps and schools working the bay all season, and Supertubos is a few minutes down the road.

Summers are cool and breezy at 21–24 °C, with the nortada building in the afternoon and the odd foggy morning. Winter is mild at 13–15 °C, with the biggest swells of the year. The sea is cold Atlantic, sitting at about 15–17 °C in summer and rising slightly into the autumn, so a wetsuit is normal here for most of the year.

When is the sea warmest at Baleal?

In September and October, when it can reach 17–18 °C. This part of the coast is one of the coldest on the mainland because upwelling runs all summer, and a hot day on land makes no difference to the water. Bring or hire a wetsuit.

Why do so many people learn to surf at Baleal?

Because the two-sided bay almost always has a clean, sheltered corner with waves the right size for beginners, whatever the wind is doing. The schools are concentrated here and hire out everything you need. It also means the water gets busy in summer, so book lessons in advance.

Which side of the spit should you choose?

Follow the wind. With the usual summer northerly, the south-facing beach towards Peniche is calmer, while the north side takes the swell and the breeze. On southerly days it reverses. You can walk across in a couple of minutes, so try both.
