Conditions at Cantinho da Baia in December
December: Peak Season Fires
December is the crown jewel of the surf year. Average swell is 2.7m (8.9ft) at a solid 12.8s period, and the NW (18.6%), WNW (13.2%), and NNW (10.4%) directions combine with a healthy W component to supply consistent, powerful groundswell. The heaviest sets easily push past 2.5m (8ft), providing genuine XL days when the lows are stacked up the Atlantic. Wind is the big bonus: the offshore E/ESE/SE/SSE quadrant is at its strongest, and a year-best 36% of December days see ideal surfing conditions. As the Icelandic Low deepens and the NAO tilts negative, the storm track targets Iberia with increasing frequency. Water temp drops to 15.0°C and rain is plentiful, but the clean, long-period pulses make December a truly special time at Cantinho da Baia.
