El Muelle - surf spot statistics

Best Surf Season (October - March)

The North Atlantic winter machine spins up from October through March, delivering the highest average swell heights (1.7–2.2m) and longest periods (11.4–12.9s) of the year. While the dominant swell direction remains from the NNW to NW – outside the spot's ideal window of NNE to E – the sheer size and power allow occasional wrap around the headlands. More importantly, this is when the few optimal offshore wind events from SSW to W are most likely to align, especially in October, November, and December when the 'ideal for surfing' statistic peaks at 10%. These months are your best bet for a few days of clean, long-period groundswell with smooth faces.

Fair Surf Season (April - May & September)

Spring and early autumn offer a mixed bag. April still sees some decent NW groundswell (average 1.9m / 10.9s), but the frequency of strong onshore northerlies increases, making clean conditions rarer. May sees a drop in average period to 9.5s, with swell often being more windswell than groundswell. September is a transitional month – the average period climbs to 10.0s as the first autumn lows form, but the wind statistics show a heavy dominance of NNE winds (48.4%), which are strongly onshore for the spot. Surf quality is inconsistent, requiring careful timing.

Low Surf Season (June - August)

Summer is the low point for El Muelle. The average swell height drops to 1.4–1.6m, and periods plummet to 7.7–8.5s – mostly short-period, wind-driven chop. The swell direction is overwhelmingly from the N to NNE, which is slightly better than winter's NW, but the wind is the real killer. Northerly winds dominate over 90% of the time, ruining the surface and making for onshore, messy conditions. The 'ideal for surfing' statistic is a paltry 0–2%. This is the time to tune your gear, not your wave count. The rare chance comes from a Southerly thermal breeze in the late afternoon, but it's inconsistent and weak.

September: Signs of Life

September is a transitional month where the Atlantic begins to stir. Average swell height holds at 1.4m but the period climbs to 10.0s, indicating more groundswell energy. The swell direction is still dominated by NNW (57.4%), with N (21.0%) also present. The wind pattern remains onshore: NNE wind is 48.4% and N is 24.7%. However, there is a slight increase in Westerly and Southwesterly wind (up to 1.3% total). The ideal wind percentage is 3%. The wave quality improves: on the rare offshore day, the longer period can produce clean, fun-sized waves in the 1-1.5m range. Not prime time, but the potential is building.
