December: Peak Winter Consistency
December brings the full force of winter to Casino Pier. Average swell height holds at 4-5ft (1.2-1.5m) and average period is 7.1s, with a wide directional spread that reflects the storminess of the season. S and SSW swells are common at 10.1% and 8.1%, while E (7.6%), SSE (7.5%), WNW (6.6%) and NW (6.1%) all contribute. The most powerful events come from Nor'easters that set up a long E/NE fetch over the continental shelf before winds shift offshore.
December has one of the most reliable offshore wind patterns of the year. WNW leads the wind rose at 15.8%, followed by W 12.1%, NW 11.9% and NNW 10.7%, and ideal surf conditions sit at 32%. The tradeoff is cold: air temperatures average 3.0°C, water drops to 9.2°C, and winter storms can blow hard. Pick the post-frontal windows and the pier offers some of the biggest, cleanest surf of the season.
