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.

January at Santo Amaro offers solid surf conditions with an average swell height of 2.2m and a strong 13s period, providing powerful, well-spaced waves. The best swells come from the WNW and NW directions, dominating the distribution with consistent heights between 1.5m and 2.5m, making up a significant portion of the month's conditions—ideal for intermediate to advanced surfers. SSW and SW swells also contribute with decent energy, though less frequently. Wind conditions are favorable 38% of the time, with light to moderate offshore or cross-offshore winds (NNE to ENE) helping to clean up the waves. However, stronger onshore winds (WNW to NW) can occasionally disrupt conditions, particularly when speeds exceed 20kph. Overall, January delivers reliable, high-energy surf with plenty of quality sessions, especially when winds align.
