San Augustin - surf spot statistics

Best Surf Season (July - October)

The heart of summer and early fall delivers the most consistent and high-quality surf at San Augustin. The Pacific storm track shifts, and we see a climatological uptick in powerful, long-period SSW and S swell trains marching straight into this south-facing beach. Average wave heights hover in the 1.6m range, with periods frequently stretching past 13 seconds – that's powerful and punchy stuff. Critically, the percentage of ideal offshore wind (N, NNE, NE, NNW) peaks during these months, often exceeding 55% and hitting 62% in July. This combination of consistent, well-aligned swell and clean, offshore breezes creates firing conditions that can rival any point in Mexico. While the occasional tropical disturbance can add extra juice, the reliable groundswell is the main draw.

Fair Surf Season (November - January & April - June)

The shoulder seasons bring a mix of quality and trade-offs. In late fall and early winter (November-January), the North Pacific kicks into high gear, sending NE and ENE swell into the region. While this swell doesn't align perfectly with the south-facing beach – it can still produce rideable, often fun-sized waves (0.5-1.5m) particularly when the wind is clean. Offshore wind frequency remains solid (59-62%), but the swell direction is less than ideal, so you have to pick your moments. The spring months (April-June) flip the script: the swell direction improves dramatically, with SSW and S accounting for over 85% of the energy, and wave periods climbing above 13 seconds. However, the wind patterns become more fickle, with ideal offshore rates dropping to 45-52%. This means you'll often need a northerly breeze early in the day to score the best quality, but when it all lines up, the waves can be absolutely world-class.

Low Surf Season (February - March)

The late winter and early spring lull is the quietest period for San Augustin. Although the average swell height holds steady around 1.5m and periods are still long (12-13 seconds), the split in swell direction hurts consistency. A significant portion of the energy comes from the NE and ENE quadrant – which wraps in with less power and form on this south-oriented beach. Simultaneously, the wind patterns become less reliable for surfers: the percentage of ideal offshore wind drops to 47-53%, while onshore and cross-shore winds from the WSW, W, and SW increase their grip. This often leads to bumpy, lumpy conditions, especially in the afternoon. The result is a season of frustrating potential – the swell is there, but waiting for a clean window becomes a game of patience. March is particularly tricky as the trade winds strengthen. Still, keen surfers can find the odd morning glass-off when a winter swell lines up right.

September: Summer's Last Stand

September maintains the high quality as the peak season begins to wind down. Average swell height edges up to 1.7m – the highest of the year – with a still lengthy 13.2s period. Swell direction remains excellent: SSW (53.7%) and S (24.0%) combine for 77.7% of the total, with SW (10.7%) adding more. Wave heights from SSW are concentrated in the 1.5-2m range (28.9%) and 1-1.5m (20.5%), so plenty of solid surf. Wind conditions are ideal 54% of the time. The offshore flow from NW (9.9%), WNW (10.5%), and NNW (7.0%) is still common, but onshore winds from W (11.5%) and WSW (8.0%) become more frequent, especially in September's later half as the Pacific pattern shifts. The hurricane season peaks this month, adding the potential for extra-large pulses from tropical systems. These can send massive, long-period SSW swell into the coast, but often with challenging winds. Overall, September offers a mix of consistent groundswell and a growing chance of stormy disruptions. A great month for experienced surfers who can handle varying conditions.
