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.

In May, Atlântida Pier offers surfers a mix of conditions with an average swell height of 1.4m and a decent period of 9.5s, indicating consistent, well-spaced waves. The majority of swell comes from the southeast to south-southeast, with the most frequent wave heights in the 1-1.5m range (15.39% from SSE) and a notable percentage of larger waves in the 1.5-2m range (8.46% from SSE). About 27% of the time, winds are ideal for surfing—typically light to moderate and offshore or cross-offshore, favoring clean faces. However, winds from the north to northeast can occasionally disrupt conditions, bringing stronger onshore winds (10-30kph) that may affect wave quality. Overall, May provides fair to good surfing opportunities, particularly when SSE swells align with favorable winds, offering surfable waves with occasional overhead sets.
