Espinho, Portugal, offers surfers consistent conditions year-round, though the best months for quality waves and favorable winds are typically from October through March. During this period, ground swells dominate, accounting for 62-89% of the swell activity, with mean swell sizes ranging from 1.3m to 1.8m—ideal for intermediate to advanced surfers. The winter months, particularly December to February, deliver the largest and most consistent waves (1.6-1.8m), but wind conditions are less reliable, with bad winds occurring 57-60% of the time. October and November strike a good balance, offering solid ground swells (62-74%) and marginally better wind conditions (37-39% good winds). Spring (April-May) and autumn (September) see a mix of ground and wind swells, with smaller waves (1.1-1.3m) and poorer wind reliability (70-75% bad winds). Summer (June-August) is the least favorable, with weak, wind-dominated swells (0.9m) and onshore winds 76-79% of the time. For surfers prioritizing wave quality, winter is optimal despite the wind variability, while those seeking a compromise between swell and wind may prefer late autumn or early winter. Advanced riders will find the biggest challenge in peak winter, while beginners might prefer the smaller, less consistent waves of late spring or early autumn.
