Conditions at Sao Pedro de Moel in December
December: Winter Peak
December is the crown jewel of the Portuguese winter. The average swell height is 2.3m (7.5ft) with a period of 12.7s, and the ocean is loaded with long-period energy. Swell directions are ideal: NW (24.1%), WNW (20.6%), W (8.0%) and NNW (7.0%) dominate, with a decent showing of WSW and SW (4.5% combined) that can also wrap in, though less favourably. Many waves are in the 2-2.5m (6.6-8.2ft) range, with over 1% of NW swell exceeding 2.5m (8ft) - XL days are on the table.
Wind conditions are the best of the year. Ideal wind is 37% - the highest of any month. The offshore sector (E, ESE, SE, SSE) accounts for a remarkable 35.9% of all winds, and those are often light to moderate. The Azores High and a cold European landmass often combine to set up a classic easterly (offshore) flow, giving clean, glassy faces on the WNW beach. Water temp is 14.5°C (58°F), air averages 10.5°C (51°F), and precipitation is 3.55 mm/day. December is the ultimate month for big, clean, powerful surf at Sao Pedro de Moel.
