Conditions at Apollonas in December
December: Prime Time on the North Side
December delivers the strongest seasonal signal of the year. Average swell height climbs to 1.2m (3.9ft) with a period of 5.3s, and the N/NE window sits at 25.6% plus another 18.7% from NNW. N and NNE swells show their beefiest distribution of the year - N alone has 4.0% in the 1.5-2m range and 3.5% in the 2-2.5m range. More important, the wind balance tilts favorably: offshore S-SW winds total 30.6%, the highest of any month, while onshore N-NE winds are 27.1%. Ideal conditions are 6%, tied with January, but the extra offshore wind days make December a favorite. Cold fronts and Mediterranean low-pressure systems are in full swing, and when the classic 'southerly after a north pulse' setup occurs, Apollonas turns on for punchy, clean 3-5ft (0.9-1.5m) peaks with occasional bigger bombs. Air temperatures average 14.2°C (min 5.6°C, max 21.2°C), precipitation is high at 2.56mm/day, and the water temperature is 17.3°C. Hooded 4/3, extra wax, and a flexible session plan are the winter keys.
