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 August, Cabedelo de Viana offers average surf conditions with a mean swell height of 1.2m and a solid period of 9.4s, indicating consistent, well-spaced waves suitable for intermediate to advanced surfers. The swell predominantly comes from the NW and WNW directions, with 18.8% of waves in the 1-1.5m range from the NW and 17.72% from the WNW, providing clean, rideable waves. Larger sets (1.5-2.5m) are less frequent but present, mainly from NW and WNW, offering occasional punchier conditions. Wind conditions are surfable 38% of the time, with the most favorable scenarios occurring when lighter winds (10-20kph) prevail from the NNW or N, minimizing onshore chop. However, stronger northerlies (20-30kph+) can disrupt conditions, particularly later in the month. Overall, expect small to mid-sized, groomed waves with occasional bigger days, best suited for those comfortable with varying wind interplay. Early sessions often provide the cleanest rides before afternoon breezes.
