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.

November at Cabedelo de Viana offers solid surf conditions with a consistent mix of power and rideable waves. The average swell height is 2.2m with a strong 12.0s period, indicating well-organized, powerful waves. The dominant swell directions are from the W (12.6% of waves over 1.5m), WNW (26.1%), and NW (18.5%), which align best with the break and provide clean, high-quality lines. Smaller contributions from SW and WSW add diversity but are less consistent. Wind conditions are best 37% of the time, typically when lighter offshore winds (N to ENE) prevail, grooming the swell. However, strong onshore winds from the S–W quadrant can create chop, especially at 20+ kph. The most reliable windows occur when WNW swells meet NE winds—expect powerful, well-shaped waves in the chest-to-overhead+ range, with bigger days reaching 2.5m+. This spot rewards experienced surfers who can handle powerful swells, though mid-sized days (1.5-2m) offer plenty of opportunity. Watch for wind shifts, but November delivers a strong combination of size, energy, and rideable conditions.
