El Mongol - surf spot statistics
El Mongol seasonal overview
Best Surf Season (October - March)
The North Atlantic delivers its full fury during these months, with powerful extratropical cyclones churning out consistent, long-period swell from the NW to NNW that directly hits El Mongol's north-facing beach. Average wave heights range from 1.4m to 1.8m and periods frequently exceed 11s, often reaching 12-13s. The NAO index often turns negative, steering storm tracks southward and feeding the Bay of Biscay. Offshore winds from the S and SSW blow reliably 48-60% of the time, creating clean, glassy faces. This is the prime window for pumping, firing surf up to 2.5m+ on the best days.
Fair Surf Season (April - May & September)
As the North Atlantic slowly transitions, swell energy drops with average heights around 1.0-1.3m and periods settling into the 9.8-10.6s range. The wind patterns shift: the frequency of ideal offshore winds decreases to 27-33%, and cross-shore or light onshore conditions become more common. Still, late-season storm pulses in September can deliver solid NW swell with punchy, rideable waves when the synoptic setup aligns. Spring months offer fun-sized surf for groveling, but expect less consistency.
Low Surf Season (June - August)
Summer brings the Azores High dominating the eastern Atlantic, suppressing storm activity. Swell becomes small and short-period (0.9m, 8.7-9.0s on average), mostly from decaying NW swell trains. The wind pattern flips: onshore N and NE breezes become prevalent, and offshore winds from the south occur only 16-20% of the time. The result is typically choppy, messy conditions with small, weak waves. Only the occasional lucky window of S winds and a stray long-period swell can salvage a session, but generally this is a time for flat spells and groveling.

Conditions at El Mongol in February
February: Sustained Winter Swell
February maintains the same high-energy pattern as January, with average swell height of 1.8m and a 12.6s period. The swell direction shifts slightly: NW (38%) remains dominant, but NNW picks up to nearly 20%, indicating more frequent deep lows passing close to the Bay of Biscay. The wind remains favourable: offshore quadrants (S-SW) account for about 23% of observations, contributing to the 50% ideal wind rating. Expect solid, rideable surf most days, with occasional XL sets from the NW exceeding 2.5m on the charts. The key is timing the wind – when a high pressure ridge builds over the Iberian Peninsula, it channels clean S winds that groom the swell into flawless walls.
