December: Winter's Reliable Roar
December is Tullan Strand at its rawest. Average swell height reaches 5-6ft (1.7m) and the period is a strong 12.2s, delivering long-period, powerful groundswell straight into the west-northwest-facing beach. The swell rose shows WNW (27%), W (20%), NW (13%), and WSW (7%), with a healthy share of 5-8ft (1.5-2.5m) waves from the Atlantic. Offshore wind is ideal 31% of the time, one of the better monthly scores of the year, so when the wind does settle into the east through southeast, the place will clean up quickly. This is the heart of the season, driven by a relentless succession of deep lows across the North Atlantic; a positive NAO pattern will only amplify the pulse. Air temperatures hover near 5.0°C, water temperatures drop to 9.9°C, and precipitation is at a wet 4.57mm/day.
