December: Summer Lull Sets In
December closes the year with the most summer-like pattern. Average swell is 4-5ft (1.2-1.5m), but the period is back to 10.9s and ideal wind bottoms out at 13%. Swell direction is dominated by SSW at 55.4%, with S at 21.4% and SW at 17.4%, but the heights are mostly clustered in the 2-3ft (0.5-1m) and 3-5ft (1-1.5m) categories. The long, powerful winter groundswell is gone, and the waves are softer and less focused.
Winds are overwhelmingly onshore. SSE (17.5%), SE (12.9%), S (12.3%) and SSW (10.6%) rule the day, making clean conditions rare. Offshore north flow is essentially absent, with ideal winds at 13% - the same as January. The small windows come with dawn glass-offs or a pre-frontal NW breeze. Air temperature is 18.7°C and water has warmed to 17.8°C, so the beach is inviting. But for serious surfers, December means playing the patience game and betting on morning light.
