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 September, Atlântida Pier offers fairly consistent surf with an average swell height of 1.6m and a decent period of 8.9s, providing well-formed waves. The swell predominantly comes from the east to southeast (ENE to SSE), with the highest frequency in the 1-2m range, making up a significant portion of the conditions. Clean, rideable waves (1.5-2.5m) are common, especially from the E and ESE directions. Wind conditions are less ideal, with only 15% of days offering favorable onshore/light winds—most winds are NE to ENE, often blowing in the 10-30kph range, which can create chop. Surfers should watch for days when winds shift lighter or offshore (W or NW, though rare), as these will provide the best conditions. Overall, September delivers decent surf with a mix of rideable days, though wind interference is a frequent challenge.
