Conditions at Santa Comba in December
December: Winter Solstice Power
December closes out the year in peak winter form. Average swell height is 2.8m (9.2ft), average period is 12.6s, and ideal wind is back up to 32%. The swell is dominated by NW (14.6%), WNW (11.5%), NNW (7.9%), and W (7.4%), with the full westerly-to-northerly spectrum ensuring a good mix of groundswell. Wind conditions are very favorable overall: SSW (14.1%), S (10.9%), and SW (9.8%) lead the list, while ENE (9.6%) and E (7.9%) are secondary. The storm track is now at its southernmost point, which means more low pressure systems tracking near or over the Bay of Biscay. When those systems are west of the region, the pressure gradient drives offshore south/southwest winds over Santa Comba, grooming the NW swell into clean, powerful lines. Water temps are a cold 14.0C, air temps average 9.7C, and precipitation is high at 4.37mm/day. This is serious surf season, and the ocean delivers on a regular basis.
