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.

November at Santo Amaro offers solid surf conditions with a consistent swell averaging 1.9m and a favorable period of 11.9s, ensuring well-formed, powerful waves. The dominant swell direction comes from the WNW and NW, contributing to the majority of waves in the 1-2.5m range—ideal for intermediate to advanced surfers. Smaller, more manageable waves (0.5-1.5m) are also present but less frequent, making the spot versatile across skill levels. Wind conditions are surfable 42% of the time, with lighter offshore or cross-shore winds (typically NNE to E) helping to clean up the waves. However, stronger onshore winds (WNW to NNW) can occasionally deteriorate conditions, particularly when exceeding 20kph. Overall, November delivers reliable surf with good size and shape, especially when wind and swell align. Keep an eye on wind forecasts for optimal sessions.
