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.

October at Atlantida Pier offers fairly consistent surf conditions with an average swell height of 1.5m and a decent period of 8.5s, suggesting mostly clean, well-organized waves. The dominant swell directions are from the east (ENE, E, and ESE), contributing the majority of rideable waves in the 1-2.5m range, with the sweet spot being 1-2m—ideal for intermediate to advanced surfers. However, winds are a mixed bag; only 15% of the time are they truly favorable (typically light and offshore). The prevailing winds tend to come from the NE and ENE, often blowing at 20-30kph, which can create choppy conditions. While there’s a solid chance of scoring clean shoulders, keep an eye on wind forecasts, as cross-onshore breezes are common. Early mornings or specific wind shifts may provide the best windows for glassy sessions. Overall, it’s a month with potential, though patience and timing will be key.
