Sea temperatures are consistently low, even in the warmer months. During summer, from December to February, the water usually sits around 14–16 °C, which feels cold despite milder air temperatures. Autumn brings a slight cooling to roughly 13–15 °C, while winter is the coldest period, often around 10–12 °C. In spring, the ocean slowly warms again, generally ranging between 11–13 °C, though rapid weather changes can make the water feel colder at times.
