This page shows the water temperature at Vilamoura 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.

Vilamoura sits in the central Algarve between Quarteira and the red cliffs of Praia da Falésia. Facing south and sheltered from the northerly wind, it typically has calm, mild water all summer long, and the marina adds extra shelter on windy days.

Frequently asked questions

When is the sea warmest in Vilamoura?

The water is warmest in August, averaging 18.9 °C, and coldest in March at 15.6 °C. The Algarve peaks in late summer, well after the hottest weather on land, and September usually beats June comfortably.

Why is the water colder than the air in Vilamoura?

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.

What can you do in the sea in Vilamoura?

The marina is the launch pad: sailing, coastal cruises to the caves, parasailing and jet skis in high season. For a quieter day, the kilometres of sand below the Falésia cliffs give calm swimming away from the bustle.
