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.

July at Atlântida Pier offers surfers consistent but often small to medium-sized waves, with an average swell height of 1.3m and a solid period of 9.1s, indicating decent energy despite the modest size. The swell direction is primarily from the SSE, E, and SE, with the most frequent waves in the 1-1.5m range (peaking at 13.29% for SSE) and some larger sets up to 2.5m (particularly from SSE and SE). Wind conditions are less favorable, with only 26% of the time being ideal—typically when lighter offshore or cross-offshore winds (ENE or E) prevail. Stronger onshore winds from the N/NE/SW/W sectors can disrupt conditions, especially at higher speeds (above 20kph). Expect a mix of rideable days with clean, smaller waves (1-1.5m) and occasional larger, wind-affected sessions. Patience will reward those waiting for the cleaner SSE or E swells paired with lighter winds.
