Conditions at Guincho in November
November: Big Atlantic Swell Returns
November is one of the most consistent months of the year for serious surf at Guincho. Average swell reaches 7-8ft (2.1-2.4m) with 12.0s periods, and while NW still leads at 23.7%, there is a healthy mix of WNW and NNW energy that keeps the beach moving. By early winter, the Icelandic Low is firing on all cylinders, and the storm track routinely aims lows at the Bay of Biscay and the Portuguese coast. This brings not only size but also longer-period, better-shaped groundswell. Ideal wind percentages improve to 22%, with NNW weakening to 17% and N/NNE winds sharing the rest - many of those northern winds are light enough in the morning to leave the surface clean. Rain reaches its annual peak at 3.0mm per day and air temps drop to 15.6°C, while water temps cool to 17.0°C. This is the month to hunt a depression in the Atlantic and score a firing, overhead-to-double-overhead day before winter's heavyweights take over.
