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 October, Cabedelo de Viana offers solid surf conditions with an average swell height of 1.9m and a decent period of 11.3s, providing well-formed, powerful waves. The best swells come predominantly from the WNW and NW directions, with a strong frequency of waves in the 1.5-2.5m range, ensuring consistent surfable energy. While smaller waves (0.5-1.5m) from WSW and W also contribute, the larger, more powerful swells from the NW quadrant dominate. Wind conditions are favorable for surfing 40% of the time, with lighter winds (10-20kph) being most common. Offshore or light cross-shore winds from the N to NE occur occasionally but are outweighed by onshore winds from the SSW to W, which can create choppy conditions at times. Overall, October delivers reliable surf with good size and shape, though wind conditions can be hit or miss. Advanced surfers will find the best sessions when NW swells coincide with lighter winds.
