December: Peak Size and Power
December is the statistical peak of the season. The average swell height hits 9.8ft (3.0m) - the largest of any month - with a commanding 12.8s period. The swell directions are more mixed than mid-winter, but W (10.8%), WNW (12.5%) and NW (8.2%) still dominate, along with a more meaningful WSW (4.4%) and SW (1.9%) presence. Those southwest components are crucial: they light up the beach perfectly. Ideal wind scores 50%, and the main problem is the usual parade of S (14.6%) and SSE (13.9%) winds spinning around approaching lows. Water temp sits at 11.0°C, air temps average 9.2°C, and December is the wettest month with 9.69 mm/day. It is a month for heavy-water confidence; when the timing works, the reward is serious, pumping Northwest winter surf.
