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.

June at Cabedelo de Viana offers decent surf conditions with a mix of rideable days and occasional calm spells. The average swell height is 1.3m with a solid period of 9.6s, indicating consistent and relatively clean waves—ideal for intermediate to advanced surfers. The dominant swell direction is from the WNW, NW, and WSW, contributing to well-shaped waves, especially in the 1-2.5m range, which occurs frequently. Wind conditions are favorable 35% of the time, with light to moderate winds from the NW and W being the most common. However, stronger northerly winds can occasionally create chop, particularly when speeds exceed 20kph. For the best sessions, aim for days when the wind stays under 20kph and the swell holds in the 1.5-2m range from the WNW or NW. While not a powerhouse month, June provides enough opportunities for quality surfing, especially if timed right.
