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 July, Cabedelo de Viana offers generally manageable surf conditions with an average swell height of 1.2m and a decent period of 9.2s, providing enough energy for intermediate to advanced surfers. The majority of swells come from the WNW and NW directions, with waves in the 1-2m range being most frequent—making for consistent, medium-sized surf ideal for performance turns and even some powerful sections. Wind conditions are favorable 34% of the time, but northerly and northwesterly winds can be an issue, often blowing in the 10-30kph range, which may create chop or cross-shore interference. Early mornings or late afternoons typically offer cleaner conditions due to lighter winds. The spot handles varying tides well, though mid-tide sessions often provide the best shape. While not the biggest or most powerful month, July delivers reliable surf for those looking for fun, rippable waves with occasional overhead sets.
