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.

July: Prime Time & Offshore Bliss

July stands out as perhaps the best month at San Augustin. The average swell height remains a solid 1.6m, with a 13.6s period – very powerful and long. Swell direction splits almost evenly between S (42.2%) and SSW (43.3%), giving us 85.5% from the optimal directions. The waves are not as top-heavy as earlier months but are incredibly consistent, with 20.3% of S swell in the 1-1.5m range and 19.1% in the 1.5-2m range. The wind turns ideal a remarkable 62% of the time – the highest of the year. Light offshore NW (14.9%), WNW (11.6%), and NNW (9.5%) winds dominate, with very little onshore flow from the S or SW. This means pristine, glassy conditions are common, especially in the morning. The combination of consistent S/SSW groundswell and reliable offshore winds makes July a dream month for surfing. Expect firing, rippable waves with long-period energy.
