Foz - surf spot statistics

Foz, Spain, offers consistent surf conditions year-round, but the best months for surfers seeking quality waves and favorable winds are from October through March. During this period, ground swells dominate, providing powerful and well-organized waves, with mean swell sizes ranging from 1.7m in October to 2.3m in January. The highest likelihood of clean conditions occurs in October with 30% good wind conditions, though wind quality remains relatively low overall, rarely exceeding 30%. Winter months like December and January deliver the largest waves (2.1m–2.3m) but also come with the worst wind conditions (73–76% unfavorable). Spring and summer (April–September) see a shift toward wind swells, reducing wave quality, with smaller sizes (1.1m–1.6m) and choppier conditions due to persistent onshore winds. September and November stand out as transition months, offering a balance of decent swell size and slightly improved winds. For advanced surfers prioritizing size and consistency, winter is ideal despite the wind challenges, while intermediates might prefer late autumn or early spring when swells are still respectable (1.7m–2.0m) and winds are marginally better. Avoid summer if seeking powerful waves, as wind swells and smaller sizes prevail.

September at Foz, Spain, offers decent surf conditions with an average swell height of 1.4m and a solid period of 10.0s, ensuring well-formed and rideable waves. The dominant swell direction is from the NNW, contributing the largest share of waves in the 1-1.5m and 1.5-2m ranges, providing consistent mid-sized waves. Smaller contributions come from NE and NW swells, adding variety. Wind conditions are favorable for surfing 29% of the time, with the most surf-friendly winds coming from the north and northeast at light to moderate speeds (0-20kph). However, ENE and E winds (10-30kph) occur frequently and can create chop, especially at higher speeds. Overall, September delivers workable waves for intermediate to advanced surfers, with the best sessions occurring when winds align from the north or northeast, keeping conditions clean. Expect occasional larger sets (2m+) from NNW but mostly manageable surf with good shape due to the consistent period.
