This page shows the water temperature at Baleal today and over the next seven days, so you can pick the best beach day before you go.
Sea temperature moves much more slowly than air temperature. A hot afternoon does not warm the ocean, and a windy day can cool it fast. Checking the water itself is the only reliable way to know what to expect.
Baleal is a rocky islet near Peniche joined to the mainland by a narrow sand spit, so it has a beach on each side of the neck. Whichever way the wind blows, one side is sheltered and the other is not, which is the reason so many surf schools are based here. The water is properly cool at about 16.7 °C in August, held down by the strong upwelling that works this stretch of coast all summer.
The water is warmest in October, averaging 18.2 °C, and coldest in March at 15.0 °C. On the west coast the peak arrives late, in early autumn, because summer upwelling keeps pulling cold deep water to the surface.
The ocean gains and loses heat far more slowly than land, so it runs months behind the seasons. On top of that, the summer northerly wind pushes surface water offshore and draws cold deep water up in its place, which is why a heatwave on land so often coincides with a colder sea.
This is the surf school capital of Portugal, and the sand spit means there is a rideable, sheltered side whatever the wind is doing. Beginners take the bay, more experienced surfers head for Supertubos and the Peniche breaks nearby, and boards and wetsuits are available everywhere. When the sea is flat, boats leave Peniche for snorkelling and diving around the Berlengas.
