Cabedelo de Viana - surf spot statistics

Cabedelo de Viana in Portugal is a spot that thrives on consistent ground swells, particularly during the winter months, making it a reliable destination for surfers seeking powerful and clean waves. The best conditions are typically found from November to February, when ground swell dominates (77–92% of the time), and the mean swell size ranges from 2.1 to 2.6 meters, offering solid overhead waves. Wind conditions are less favorable during these months, with only 35–38% of days having good offshore or cross-offshore winds, but the strong, clean swells compensate for the occasional onshore winds. March and December also provide excellent swell consistency, though wave heights begin to taper slightly in March. From April onward, the swell mix shifts, with wind swells becoming more prevalent, and by summer (June–August), ground swells drop significantly (18–28%), resulting in smaller, less consistent waves (1.2–1.3 meters). September and October mark a transition back to better surf, with ground swells increasing again (48–65%) and wind conditions improving slightly (40–41% good winds). While the winter months deliver the most powerful and reliable waves, intermediate surfers may prefer the shoulder seasons (September–October and March–April) for a balance of decent swell size and slightly better wind odds. Overall, Cabedelo de Viana is a winter-centric spot, best suited for experienced surfers who can handle larger swells and variable winds.

In September, Cabedelo de Viana offers fairly consistent surf conditions with an average swell height of 1.4m and a strong average period of 10.6s, indicating well-organized, powerful waves. The dominant swell directions are WNW, NW, and W, contributing the majority of rideable waves, particularly in the 1-2.5m range. Smaller swells (0.5-1.5m) from SW and WSW also occur but are less frequent. About 41% of the time, wind conditions are favorable for surfing, typically light to moderate (under 20kph) from northerly or northwesterly directions, while stronger winds (20-30kph) from N/NNW can create choppier conditions. Cleaner sessions are more likely with offshore winds from the NE/ENE, though these are less frequent. Overall, September provides solid surf opportunities with decent size and quality, though wind conditions can vary. Advanced surfers will find the best sessions when longer-period NW/WNW swells align with lighter winds.
