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 March, Cabedelo de Viana offers solid surf conditions with an average swell height of 2.1m and a strong period of 12.3s, ensuring powerful, well-formed waves. The dominant swell directions are WSW, W, and WNW, which provide the best wave quality, particularly in the 1.5–2.5m range, where consistency is high. Smaller swells (0.5–1.5m) are less frequent, and larger swells (>2.5m) occur occasionally, adding variety. Offshore winds, critical for clean surf, are favorable 38% of the time, with lighter winds (10–20kph) coming from the NNE, NE, or E being ideal. However, stronger onshore winds (20–30kph+) from the N, NW, and S can disrupt conditions. Surfers should target days when the WNW/W swells align with light ENE or NE winds for the best sessions. Overall, March delivers consistent, powerful surf with occasional excellent windows for advanced riders.
