This page shows the water temperature at Odeceixe 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.
Odeceixe sits on the border between the Alentejo and the Algarve, where the Seixe river meets the sea in a half-moon of sand between two cliffs. The river side is shallow, still and several degrees warmer, while the ocean side faces west and runs cool, near 16.7 °C in August. The balance between the two shifts with the tide, which is part of why the beach works for families and surfers at once.
The water is warmest in October, averaging 18.6 °C, and coldest in March at 15.4 °C. On the Alentejo and Vicentina coast the sea behaves like the west coast, with summer upwelling keeping the water cool even in August, so the warmest readings arrive in early autumn once the nortada eases. River-mouth beaches such as Milfontes and Odeceixe run a few degrees warmer than the open ocean.
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.
The half-moon of sand gives you two options at once: the still river channel for paddling, floating and easy swimming, and the ocean side for surf. Surf schools work the beach through the summer, and the walk up onto the cliffs at either end is short and worth doing. The tide changes the balance between river and sea through the day, so it is worth checking before you settle in.
