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.

December at Atlantida Pier offers surfable conditions, though with some variability. The average swell height is 1.4m with an 8.0s period, providing decent energy for intermediate surfers. The swell predominantly arrives from ENE to SSE, with the highest frequency in the 1-1.5m range (peaking from E and ENE). Larger sets (1.5-2.5m) occur less frequently but can deliver punchier rides, especially when ENE or SSE swells combine with offshore winds. Wind conditions are inconsistent—only 16% of the time are they ideal for surfing. The most common winds come from NE to E, often blowing onshore at 10-30kph, which can create choppiness. However, occasional ENE or SSE winds under 20kph may provide cleaner sessions. Expect a mix of waist-to-head-high waves, best on mid-to-high tide if the sandbanks are favorable. While not epic, December delivers enough rideable days for committed surfers, especially when wind and swell align.
