December: Deep Winter Groundswell
December rounds out the year with peak winter conditions. The average surf height is around 6-7ft (2.1m) and the period is 11.7s, firmly in the powerful long-period category. The swell rose still has W at 31%, WSW at 13% and WNW at 10%, so the beach sees a steady diet of strong, focused groundswell. Ideal offshore winds blow 23% of the time, but with the Icelandic Low at full strength and storms tracking straight through the Atlantic, onshore W and NW winds dominate many days. When the wind drops out or goes southeast, Polzeath delivers some of the heaviest, most memorable surf of the year. Water temperature is 11.1°C, air 8.7°C and precipitation averages 4.15mm/day, so bring the thickest rubber you own.
