Praia do CDS - surf spot statistics

Praia do CDS in Portugal is a surf spot with consistent conditions year-round, but the best months for surfers generally fall between October and March, when ground swell dominates and wave heights are more favorable. During these months, ground swell frequency ranges from 63% (October) to 91% (January), with mean swell sizes between 1.5m and 2.1m, peaking in January and December. Wind conditions are less ideal, with good wind days averaging only 24-29% from November to February, but the strong, clean ground swells often compensate for the prevailing onshore winds. The winter season offers the most powerful and consistent waves, though the highest percentage of bad wind conditions (up to 76% in December) means patience is required. From April to September, ground swell diminishes significantly (15-64%), replaced by wind swell, and wave heights drop below 1.6m, making the surf smaller and less reliable. However, late spring and summer (May-August) see slightly better wind conditions (32-38% good wind days), but the swell is weaker and mostly wind-driven. September and October serve as transitional months, with improving ground swell and manageable wind conditions—offering a good balance between consistency and rideable waves. Overall, advanced surfers will prefer the winter months for sizable, clean ground swells, while intermediates may find better opportunities in late autumn or early spring when winds are less harsh and waves remain surfable.

In July, Praia do CDS offers relatively small but rideable surf with an average swell height of 1.1m and a decent period of 9.0s, providing some energy for intermediate surfers. The swell is predominantly from the northwest (NW and WNW directions), with the majority of waves falling in the 0.5-1.5m range, offering consistent waist-to-shoulder-high sessions. Larger swells (1.5-2.5m) do occur but are less frequent. Wind conditions are a mixed bag, with only 32% of the time being ideal for surfing—typically light offshore or cross-shore winds from the north or northeast. However, strong northerly and northwesterly winds (10-30+ kph) are common, creating bumpy or choppy conditions. If you’re selective with sessions during early mornings or wind lulls, July can deliver fun, mellow waves, but don’t expect powerful or clean conditions consistently.
