Conditions at Fistral Beach in December

December: Midwinter Giants

December delivers some of the biggest, most powerful surf of the year at Fistral. Average swell height sits at 2.1m (6.9ft), the period at 11.7s, and the Atlantic storm track is in full swing. W, WSW, and WNW directions dominate, with WSW contributing 13.1% and WNW 10.4%; the combination of these long-fetch swells wraps straight into the west-facing bay and can quickly push into the 2.5m-plus range during strong events. Wind is again the deciding factor: SW and WSW are the most frequent winds, but 23% of the time conditions are ideal, usually when a high pressure ridge extends over the continent and delivers east or SE airflow. Air temperatures are cold, around 8.7°C, and water temperature falls to 11.1°C. Rain is plentiful at 4.15 mm/day. For experienced surfers, December offers the classic Fistral winter grind: big, raw, and occasionally perfect.
