The sea temperatures in this region tend to follow a typical maritime climate, with cooler waters compared to southern Portugal. In the summer months, especially in July and August, the average sea temperature ranges between 18°C and 20°C (64°F to 68°F), making it refreshing for swimming and water sports, but still on the cooler side compared to more southern regions of the country.
As the seasons change, the ocean temperature gradually decreases.

During the winter months, from December to February, the sea temperature can fall further, averaging around 14°C to 15°C (57°F to 59°F). These cooler temperatures make the waters less inviting for casual swimmers but still allow for other activities like surfing or enjoying the coastal scenery.
