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.

April at Cabedelo de Viana offers decent surf conditions with a mix of rideable swells and variable winds. The average swell height is 1.8m with a solid 11.3s period, providing consistent energy for quality waves. The swell is predominantly from the W, WNW, and NW directions—these angles generate the majority of the surfable waves (1.5–2.5m range), ensuring good shape and power. Smaller swells (1–1.5m) are also frequent, making it accessible for intermediate surfers. However, wind conditions are a limiting factor—only 35% of the time is it ideal (offshore or light cross-shore). The wind is often from the N to NW sectors, bringing stronger onshore gusts (20–30kph), which can degrade wave quality. For the best sessions, watch for WNW swells paired with lighter SSE to SW winds. Overall, April is reliable for surf, but wind management is key.
