Conditions at Lincoln City in December
December: Peak Winter Power
December is statistically the biggest month of the year at Lincoln City, with an average swell of 9.2ft (2.8m) and a powerful 12.8s period. The swell directions are W (18%), WNW (17%), WSW (7%), and SW (3%), but the height distribution skews heavily toward 5-8ft (1.5-2.5m) and larger, with a meaningful share over 8ft (2.5m). This is real, heavy, mid-winter groundswell generated by intense Aleutian Low pressure systems traveling across the North Pacific. Ideal wind is 33%, and the offshore E/ESE/SE directions still combine for 29% of the wind rose, so the surf can be both big and clean when the timing is right - though the smart money is on dawn patrol before the afternoon westerlies develop. Expect cold air at 5°C, water at 10.2°C, and 9mm/day of rain as the North Pacific channel stays active. December is serious surf.
