Conditions at Foz do Arelho in November
November: Cold Fronts and Overhead Power
November delivers the first fully consistent winter groundswell month. Average wave heights rise to 8ft (2.5m), periods to 12.1s, and the Atlantic storm track is in full swing. Swell directions are again nearly all in the sweet spot: NW at 20.6 percent, NNW at 15.9 percent, WNW at 13.5 percent, with W adding another 5.4 percent. Ideal offshore wind settles at 27 percent, making November one of the most reliable months for quality sessions.
