Conditions at Sines in November
November: Stormy Power, World-Class Potential
November is where Sines gets serious. Average swell height hits 6.9ft (2.1m) with an average period of 12.0 seconds, and the open-ocean mix is loaded with long-period energy. The dominant NW swell still claims 29.9 percent, but WNW, W, WSW and S/SW directions all become more active, giving the south-facing beach more opportunities to line up perfectly. Rain and wind are more frequent, and ideal wind drops to 51 percent as low-pressure systems pass close to Iberia. Still, when a strong Atlantic low parks itself west of Portugal and pushes S/SW groundswell into Sines under a fresh north wind, the surf can be powerful, hollow and well worth the storm-chasing effort.
Air temperatures fall to 14.5°C, precipitation rises to 2.69 mm per day, and water temperature cools to 16.9°C. The wetsuit is back to winter thickness.
