Travelers who visit other countries primarily for beach vacations go to Alvor in the summer, when the water temperature in the Atlantic Ocean warms up well. Travelers who don't prioritize swimming can visit Alvor in spring, fall or winter.
Even on the hottest days of August, the water temperature in the Atlantic Ocean does not exceed +23°C. The bathing season starts in mid-May, when the sun starts to shine and the coastal waters warm up to +20°C.
Theoretically, hardened tourists can swim in Alvor in winter too - in January the Atlantic Ocean temperature is +16-17°C (for comparison, in Crimea the water warms up to this temperature by the end of May). In Alvor you can feel the tides in the Atlantic Ocean: the maximum water level is 3 to 4 meters.
Climatic conditions on the surface of the Atlantic Ocean are determined by its great length and the circulation of air masses. Water exchange with the Arctic Ocean, the Antarctic Seas and the Mediterranean Sea has a significant influence on the temperature regime of the ocean. The surface waters of the ocean are characterized by gradual cooling as they move away from the equator. The average water temperature in the Atlantic Ocean for the tropical region is +20°C.
