Mancora - surf spot statistics

Best Surf Season (May - October)

The southern winter unleashes its fury across the South Pacific, and Mancora feels the pulse with consistent, powerful SSW groundswells. Average wave heights hover in the 1.8m to 1.9m range with long periods often exceeding 13 seconds, delivering a solid, pumping baseline. During these months, the Southeast Pacific high-pressure system strengthens, driving a steady stream of offshore S to SSW winds that groom the waves to perfection. Ideal wind percentages peak at 71-74%, meaning clean, glassy conditions are the norm. While the swell direction is not ideal for the north-facing beach, the long-period energy wraps around the headlands, producing punchy, rippable peaks. This is the prime window for experienced surfers seeking quality.

Fair Surf Season (November - December & March - April)

The transition months see a slight drop in average swell heights to 1.6m-1.7m, but the period remains long (13.7s-14.1s). The trade winds are still favourable, with ideal wind percentages around 58-70%. However, the storm tracks become less consistent, leading to occasional lulls. Mornings often deliver the best conditions as light offshore breezes from the S-SSW quadrant groom the south swell before the afternoon sea breeze kicks in. Waves are still very surfable, though you'll need to be more selective about the days when the swell angle and wind align perfectly for that clean, wrapping wave.

Low Surf Season (January - February)

The heart of the southern summer brings a noticeable reduction in both swell height and consistency. Average wave heights drop to 1.5m, and while the period remains impressive at 14s, the energy becomes less reliable. The dominant SSW-SW swell direction continues, but the strength and frequency of South Pacific lows diminishes. Wind conditions become more variable: ideal wind percentages fall to 52-63%, with an increase in lighter, variable breezes and occasional northerly components that can ruin the surf. On the bright side, the long-period groundswell still wraps in, offering fun-sized waves on the better days, but you'll be chasing the smaller windows of clean, offshore conditions. This is the time for groveling and smaller boards.

February: The Windy Middle Ground

February mirrors January but with a slightly less reliable wind regime. Average swell holds at 1.5m with a 14.0s period, dominated by SW swell (57.3%) and SSW (14.6%). The good news: the long period continues to wrap energy into the bay. The bad news: ideal wind drops to just 52%, the lowest of the year. The S-SSW offshore flow is still present but less frequent, and we see an uptick in NW to N winds (7.1% NW, 3.9% NNW) that create onshore, choppy conditions. When the stars align—typically during a strong SW groundswell and a morning offshore breeze—the waves can be solid and fun, especially in the 1.5-2m range. But be prepared to sit out more sessions than you ride. Patience is key; watch the wind forecasts and pounce on the cleanest windows.
