December: The Winter Sweet Spot
December brings the highest ideal wind percentage of the year at 49 percent, along with serious winter swell. Average wave heights reach 7-8ft (2.3m) and the average period is a powerful 12.7s, so there is plenty of heavy, pumping surf on offer. The swell directions are slightly more mixed than mid-winter, with NW at 24.6 percent, WNW at 19.3 percent, W at 6.7 percent and even a modest WSW and SW presence, but the overall signal remains strongly favourable for the west-facing beach. NNW winds are less dominant than in summer, and the wind distribution is spread across more easterly directions, which helps explain the high clean-wind percentage. Water temperature is 15.8°C, air temperatures average 12.2°C and precipitation is high at 2.64mm/day. This is a prime month to chase solid, long-period Atlantic swell at Milfontes.
