December: Peak Size, Peak Stoke
December is statistically the biggest month of the year at Pacific City. Average swell height peaks at 9.2ft (2.8m) with a long 12.8-second period, and the swell directions are ideal: W (17.7%), WNW (16.8%), WSW (7.0%), SW (2.8%), with huge amounts of energy in the 2-2.5m (6.5-8ft) and over-2.5m (8ft+) tiers. This is the heart of the Aleutian Low's power. The wind remains surprisingly favorable for such a stormy month - ideal offshore conditions run 35% of the time, with ESE (12.3%) and E (8.3%) aligning nicely. But S (10.6%), SSE (9.1%), and SSW (8.7%) bring their fair share of rain and onshore slop. Water temp is 10.1°C, air averages 5.0°C, and precipitation hits 9.0 mm/day. When a big groundswell meets an east wind, Pacific City can be as good as it gets - charging, hollow, and epic. Just know your limits: on the XXL days, the beach break can humble anyone.
