Conditions at Byberg in December
December: Winter Solstice Storms
December is full-on winter. The average height is back up to 5ft (1.5m), the average period to 8.3s, and the North Atlantic lows are firing on all cylinders. W (13.0%), WNW (12.6%) and NW (12.0%) combine with NNW (2.1%) for 39.7% of the total swell directions. With long nights and strong temperature gradients, the storm track can produce serious, heavy swells that push right into the beach.
Ideal wind remains useful at 13%, while the offshore quadrant totals 32.6% of observations. Still, be ready for a fight: NNW winds are the single most frequent at 11.4%, and the W/NW onshore flow remains a constant threat. Water temperature is 7.9°C, air average 3.3°C and precipitation peaks near 6.69mm/day. December is for experienced winter surfers, but when a high-pressure ridge slips over Scandinavia and the wind turns east, the waves can be legitimately pumping - a proper Arctic reward to end the year.
