Atlantida Pier - surf spot statistics

Atlântida Pier in Brazil is a surf spot heavily influenced by wind swells, with ground swells playing a minor role in wave generation. Throughout the year, wind swells dominate, accounting for 65–90% of the swell conditions, while ground swells range from 10–35%, peaking between May and June. The mean swell size remains fairly consistent, averaging 1.3–1.6m, with slightly larger waves in September (1.6m). The best wind conditions for surfing occur from May to August, when good wind percentages reach 26–29%, reducing the typically high prevalence of bad winds (71–78%). September through December sees the worst wind conditions, with bad winds peaking at 85%. The optimal months for surfing Atlântida Pier are May, June, and July, when ground swell contributions are higher (35% and 26%), wind conditions improve slightly, and wave size remains consistent. Outside this window, surfers face more challenging cross-shore or onshore winds, particularly in late spring and summer. For those seeking cleaner conditions, mid-autumn to early winter offers the best balance of swell consistency and acceptable wind. However, due to the spot’s wind-dominated nature, wave quality is rarely pristine, making it more suitable for intermediate surfers who can handle choppier conditions.

March at Atlantida Pier offers surfable conditions with an average swell height of 1.3m and a solid period of 8.6s, suggesting decent energy for decent-sized waves. The predominant swell direction is from the east to southeast, with the highest frequency of rideable waves (1-2.5m) coming from the ESE, E, and SSE sectors—indicating well-aligned swells for the spot. Wind conditions are variable, with only 19% of days offering ideal offshore or light cross-shore winds (typically from the west or northwest, though these directions are less frequent). The majority of winds are onshore (ENE-E-SE), which can create chop, particularly when speeds exceed 20kph (common in NE-ENE directions). Look for windows when winds swing W/NW or drop below 10kph for cleaner faces. While larger swells (2m+) are relatively rare (~8% of occurrences), mid-sized waves (1-2m) dominate, providing consistent opportunities. The takeaway: March delivers workable waves but demands patience for optimal wind conditions. Intermediate to advanced surfers will find the most success, especially on SSE-ESE swells with lighter offshore winds.
