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 August, Atlantida Pier offers surfable conditions with an average swell height of 1.4m and a decent period of 9.0s, providing consistent energy for rides. The swell predominantly comes from the ENE to SSE directions, with the majority of waves (over 60%) falling in the 1-2m range—ideal for intermediate to advanced surfers. The best quality waves are likely from ENE and SSE directions, where cleaner swells with sufficient size and period create well-formed faces. However, wind conditions are only favorable (light onshore or cross-shore) about 22% of the time, as winds often blow from NNE to WSW, with moderate speeds (10-30kph) that can create choppiness. The strongest winds come from NNE and SW, which may disrupt wave quality. While not the most consistent month, August still delivers rideable days, especially when SSE swells align with lighter winds for cleaner, punchy waves.
