Conditions at Foz in November
November: Peak Season Power
November may be the most consistent month of the year. Average swell heights push up to 1.6m (5.2ft), periods average 11.7s, and the North Atlantic storm track is in full swing. The wave rose is all NW (38%) and NNW (24%), with WNW adding 12% - exactly the swell window Foz needs to funnel energy down the coast. Wind-wise, November posts the highest ideal percentage in the annual cycle at 43%. SSW accounts for 20% and SW for 14%, giving long stretches of offshore, groomed conditions between weather fronts. The downside is heavy rainfall (4.5mm/day) and cooling air temps (9.7°C), but the trade-off is powerful surf: when a synoptic-scale low spins up, you can see 5-8ft (1.5-2.4m) of lined-up Atlantic swell. Water temperature is 15.4°C, so a solid 4/3mm is still required.
