December: Winter Storms and Frontal Cleanups
December closes out the year with another strong month. Average swell height is 2.8ft (0.9m), the period holds at 8.6s, and the ideal wind frequency improves to 15 percent, tied for the best of the year. Swell direction is a little more balanced than October and November: E 23 percent, ENE 24, NE 15, ESE 8, along with some NNE/NNW swell at 9 and 6 percent. The consistent winter storm track sends regular pulses of NE/ENE energy toward the coast.
Winds are distinctly winter-like. NNW is the most common at 13 percent, with NW at 8 and WNW at 6, alongside E/ENE at 8 percent each. The frequent cold fronts bring strong NW/NNW breezes that are cross-offshore at best, but when the front clears and the wind clocks into the W/SW quadrant, the setup can be excellent. With water at 22.3°C and air temps averaging 19.5°C, December combines winter swell power with some of the most frequent clean-wind windows of the year.
