Costa da Caparica - surf spot statistics

Costa da Caparica in Portugal offers consistent surf conditions year-round, though the best months for surfers generally fall between October and March. During this period, ground swell dominates (74–91% of the time), providing cleaner, more powerful waves with mean swell sizes ranging from 1.5m to 2.1m. Winter months, particularly December to February, bring the largest swells (2.0m+), but wind conditions are less favorable, with bad winds occurring 62–64% of the time, often due to onshore winds from northerly or westerly systems. The shoulder seasons of October–November and March offer a good balance, with solid ground swell (63–84%) and slightly improved wind stats (35–36% good winds). April and September can still deliver decent sessions, though ground swell drops (46–64%) and wind conditions worsen (71–65% bad winds). From May to August, surf quality declines significantly—swell size drops below 1.3m, wind swell dominates (58–82%), and bad wind conditions peak (68–74%). While summer sees smaller, choppier waves, it can still be surfable for beginners or longboarders. For intermediate to advanced surfers seeking quality rides, the autumn and winter months are ideal despite wind challenges, while spring and summer are better suited for casual surfing in less demanding conditions.

November at Costa da Caparica offers solid surf conditions with an average swell height of 1.8m and a healthy period of 11.9s, indicating well-formed, powerful waves. The dominant swell directions are from the WNW and NW, making up the majority of rideable conditions, with a significant portion of waves in the 1-2.5m range—ideal for intermediate to advanced surfers. Cross-shore or light offshore winds are present 36% of the time, enhancing wave quality. Windier days often come from the N-NW, sometimes causing choppier conditions, but the prevalence of WSW-WNW swells ensures consistent setups. Expect a mix of playful mid-size waves and occasional larger, more powerful sets, particularly on NW swells. The spot works best on mid to high tides, and while not every day is perfect, November delivers reliable surf with enough good windows for scoring clean, well-shaped waves.
