December: Holiday Fun and Shifting Winds
December brings the surf season full circle. Average swell height settles at just over 5ft (1.6m) and the period remains long at 13.9 seconds. The swell direction becomes more mixed again: SW and SSW split the energy almost evenly at 46% and 44%, with WSW adding 8%. The height distribution is split between 3-5ft (1-1.5m) at 42% and 5-6.5ft (1.5-2m) at 52%. It is still a far cry from flat, but the raw power of winter is gone.
Wind quality is solid at 69% ideal, with SSW and SW winds combining for 53% of the observations and WSW another 18%. Rain begins to creep back in at 0.30 mm/day, and water temperature rises to 21.8°C, with air at 22.7°C. December is a great month for holiday surfers: fun, long-period waves, mostly clean conditions and warmer water.
