Conditions at Kolibithra in December
December: Deep Winter Returns
December closes the year with winter power built back into the North Aegean. Average swell height is 1.2m (4ft), average period is 5.3s, and ideal wind sits at 4%. Swell direction is a healthy split between N at 18.3%, NNE at 14.7%, NNW at 9.8% and NE at 1.8%, giving good direction nearly 45% of the time. The 2-2.5m (6-8ft) range appears from both N and NNE, so the heaviest days of the year are within reach. Wind is the usual problem: onshore N/NNE/NE/NNW directions total 46%, while offshore S/SSE/SSW/SW totals around 32%. The standout sessions occur when a winter low deepens in the Aegean and shifts winds into the S/SW quadrant for a day or two. Air temps average 13.9°C, water is 17.1°C, and precipitation is high at 2.92mm per day, but those cold, clean, north swell days make it all worthwhile.
