Conditions at Juist in December
December: Winter's Full Force
December rounds out the year with the same cold, powerful character as January. Average swell height is 4ft (1.2m) and the average period reaches 6.0s, the highest of the year. The North Atlantic storm track is fully engaged, and NNW swells are the most frequent at 15.1%, with W at 11.3%, NW at 10.8% and WNW/WSW not far behind. There is genuine size on the table: the 3-5ft (1-1.5m) and 5-6.5ft (1.5-2m) height classes are well represented from the W, WSW, NW and NNW directions. However, the wind is often the enemy. SW and SSW winds dominate, with WSW also strong, and ideal offshore flow appears only 7% of the time. Air temperatures drop to 4.2°C, water temps to 6.4°C and precipitation rises to 2.78 mm/day, so cold, dark and raw conditions are the norm. The rare December swell window with southeast to south-southwest wind can produce powerful, hollow, long-period-feeling waves on the north-facing banks, making it all worth it for the few patient locals.
