Matosinhos, Portugal, offers consistent surf conditions year-round, with the best months for quality waves falling between October and March. During this period, ground swell dominates (74-89%), providing powerful, well-organized waves with mean swell sizes ranging from 1.3m to 1.7m. Winter months, particularly December to February, deliver the largest and most reliable swells (1.6-1.7m), though wind conditions are less favorable, with onshore or cross-shore winds (bad conditions) occurring 58-59% of the time. October and November present a sweet spot, balancing solid swell size (1.3-1.5m) and slightly improved wind patterns (37-39% good winds). Spring (April-June) and summer (July-September) see a decline in ground swell (15-62%) and a rise in wind swell, leading to smaller, less consistent waves (0.8-1.2m). Summer months are particularly challenging, with weak swell (0.8-0.9m) and frequent poor wind conditions (65-69%). However, beginners may find these smaller waves more manageable, despite the less ideal winds. For advanced surfers targeting powerful, clean waves, the winter months (November-February) are ideal, despite the wind variability. Intermediate surfers might prefer late autumn (October-November) or early spring (March-April), when swells are still decent (1.2-1.5m) and wind conditions are marginally better. Overall, Matosinhos is a consistent year-round destination, with peak conditions occurring in the colder months when Atlantic swells are most potent.
