Conditions at Campelo in December
December: Peak Winter, Peak Power
December closes the year the way Campelo likes it: big, cold and consistent. Average swell height is around 9-10ft (2.7-3.0m), the period is an impressive 12.6s, and offshore wind conditions run at 35%. The swell rose shows NW (14.6%), WNW (11.5%) and NNW (7.9%) providing the muscle, along with a solid W component (7.4%), and over-2.5m waves are a regular feature, especially from NW and W. The wind pattern is polarised: SSW (14.1%) and SW (9.8%) keep the offshore flow alive, while ENE (9.6%) and NE (5.3%) provide annoying cross-shore spells. Water temperature drops to 14.0°C, air temps average 9.7°C and precipitation is 4.37 mm/day. This is big-wave season, and Campelo lights up whenever the south-west wind cleans up a long-period North Atlantic groundswell.
