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.

June: Peak Winter, Peak Power

June is the apex of the southern winter swell window. Average wave height reaches 1.9m with a 14.0s period, and the swell direction is almost exclusively SSW (90.6%). Over 78% of the swell falls in the 1.5-2.5m range, meaning the beach is consistently pumping. Wind is a dream: 74% of the time the breeze is from the S-SSW (offshore), and the dominance of SSW winds (27.1%) and SW winds (25.4%) ensures a clean, offshore groom. The few times the wind shifts to W or NW (10.8% and 1.1% respectively) are mostly light and do not ruin the session. The long-period energy wraps beautifully into the bay, and the high pressure over the Southeast Pacific locks in stable conditions. If you want to score solid, powerful waves with a chance of glassy perfection, June is your month.
