November: Winter's Power Builds
November delivers the first true winter swells of the season. Average height is 1.7m (5.5-6ft), period 11.9s, and ideal wind frequency a solid 44%. The wave rose shows WNW (30.0%) and NW (30.4%) sharing the load, with a respectable W (10.9%) and WSW (4.2%) direct-hit contribution. This is also the wettest month, with 3.01mm/day of precipitation, reflecting the active frontal weather. Wind directions become more mixed: NNW (18.8%) is still the dominant offshore, but NNE/NE (9.1% and 6.7%) provide clean morning alternatives. Air temperatures cool to 15.6°C and water to 16.9°C. When the NAO turns negative, low pressures can park off the Portuguese coast and pump consecutive westerly swells into Cova do Vapor. November can be heavy, powerful, and plenty hollow.
