This page shows the water temperature at Peniche 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.
Peniche occupies a peninsula with the sea on almost every side and the Berlengas islands offshore. There is nearly always a beach sheltered from the wind somewhere, from Supertubos to Baleal, but the water is among the coldest on the coast and summer fog is not rare.
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.
Surfing all year round, from school-lined Baleal to the barrels of Supertubos, is what brings most people here. The alternative is boarding a boat to the Berlengas for diving and snorkelling in clear nature-reserve water.
