Conditions at Foz do Lizandro in December
December: Winter Solstice, Winter Swells
December runs a close race with January for the top spot on the yearly power scale. Average swell height reaches 8.2ft (2.5m) with a thick 12.7-second period, as low pressure systems track relentlessly across the North Atlantic. The swell mix is west-dominant: NW 21.2%, WNW 15.2%, NNW 11.3%, W 6.1%, and WSW 3.0%-altogether a classic west-northwest setup that lines up beautifully for the beach.
Interestingly, December shows the highest percentage of ideal wind among all months (25%), driven partly by continental easterly winds that occasionally pour off the Iberian Peninsula. Those days produce sparkling, offshore surf on big groundswell-the stuff longboarders and shortboarders both dream about. With air temps at 12.3°C, water at 14.9°C, and rain at 2.69mm/day, you'll want the full winter kit. It's a fitting close to the year: powerful, cold, and full of potential.
