Santo Amaro - surf spot statistics

Santo Amaro in Portugal is a surf spot with consistent conditions year-round, but the best months for surfers depend on swell quality, size, and wind conditions. The winter months from November to February offer the largest and most consistent ground swells, averaging 1.9–2.2m, with ground swell dominance (74–91%). However, wind conditions are less favorable during this period, with only 33–41% of days having good winds, meaning offshore or light cross-shore breezes are less frequent. The strongest swells in December and January come with higher chances of onshore winds, making clean conditions rarer. Spring (March–April) sees a slight drop in swell size (1.7–1.9m) but remains solid, with ground swells still prevalent (64–84%) and marginally better wind stats (41–43% good days). Summer (May–August) is the least consistent, with smaller swells (1.1–1.4m) dominated by wind swell (59–83%), though wind conditions improve (45–49% good days). September and October are a transition period, with improving ground swell presence (46–63%) and decent wind stats (46–53%), making them a good balance between swell size and cleaner conditions. For advanced surfers seeking powerful waves, winter is ideal if you’re willing to gamble on wind luck. If you prefer smaller but cleaner waves, September–October offers the best compromise. Summer is best for beginners or longboarders due to milder conditions.

In April, Santo Amaro offers decent surf conditions with an average swell height of 1.7m and a solid 11.3s period, indicating well-organized, powerful waves. The swell is predominantly from the W to NW directions, producing clean, rideable waves in the 1-2.5m range with consistency, particularly from the WNW and NW (46.76% combined for 1-2.5m). Wind conditions are favorable for surfing 43% of the time, mostly light (10-20kph) and offshore or sideshore from the N to NE. Stronger winds (20-30kph+) come from the NNW but are less frequent. Expect a mix of mid-sized, groomed waves with good shape, though larger sets (2.5m+) are rarer (just 1.83% of swells). Overall, April delivers reliable surf with a high chance of clean conditions, best suited for intermediate to advanced surfers when WNW-NW swells align with NE winds.
