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.

April at Atlantida Pier offers decent surf conditions, though not consistently epic. The average swell height of 1.3m combined with a solid 8.9s period ensures rideable waves, often in the 1-2m range. Swell direction is predominantly from the E to SSE (peaking in SSE at 14% for 1-1.5m waves), providing clean, organized lines when paired with favorable winds. Offshore winds (ideal for surfing) occur only 22% of the time, mostly from the W to NW quadrants, while NE to E winds (often onshore) dominate, creating chop. Expect the best sessions when swells from the E-ESE (9-10% at 1-1.5m) coincide with W-WNW winds. Mid-sized days (1.5-2m) are frequent enough (SSE 8.4%, SE 3.5%), but bigger swells (2m+) are rare. Wind speeds are typically 10-30kph, with stronger NE winds disrupting conditions. Overall, April delivers surfable waves, but patience and timing are key to scoring the cleaner, less wind-affected sessions.
