December: Christmas Swell and Offshore Windows
December caps off the year with some of the most consistent surf of the season. The average swell is 6ft (1.8m) with a 12.4s period, and the direction mix is loaded with winter groundswell: NNW at 32.0%, NW at 17.6%, WNW at 5.3%, N at 9.8% and NNE at 15.6%. The 5-8ft (1.5-2.5m) range is well represented, and the long period gives Los Patos real heavy, heaving lines. This is the depth-winter wave quality that the spot is known for.
Ideal wind reaches 29%, one of the highest percentages of the year, as the land-sea temperature contrast and passing fronts produce light S/SW/WSW offshore winds between swell events. The background flow is ENE at 24.0%, E at 17.9% and NE at 14.4%, so picking the windows is the game. Air temperature averages 18.4°C, water temperature is 20.9°C, and December is the wettest month at 1.24 mm/day. End the year with a bang at Los Patos.
