Spiders - surf spot statistics

Best Surf Season (October - March)

This is the prime window for Spiders. The North Atlantic roars to life as strong extratropical storms spin up, sending long-period groundswells barreling toward the Moroccan coast. Average swell heights hover between 2.0m and 2.2m, with periods often exceeding 12 seconds, delivering powerful, heavy waves that wrap beautifully into the WSW-facing beach. Offshore wind consistency is at its peak, with the ideal N to ESE breezes blowing over 50% of the time — often from the east under the influence of a strong Azores High, ironing out the surface to glassy perfection. This is when Spiders truly fires.

Fair Surf Season (April - May)

As spring progresses, the North Atlantic storm track shifts north and weakens, and the Azores High builds northward. Average swell height drops to 1.8m—still fun-sized—but the period shortens to 9-11 seconds, making the waves punchier and less consistent. The dominant swell direction shifts strongly to NNW, reducing the direct exposure angle, so the spot sees more wrap and less power. Offshore wind frequency declines to around 30-36%, and the wind regime becomes more variable, with stronger N to NNW trades often spoiling conditions. It's a shoulder season: good days exist, but they're less frequent.

Low Surf Season (June - September)

Summer brings the doldrums to Spiders. The North Atlantic storm machine all but shuts down, replaced by the persistent Azores High and the steady, cool N to NW trade winds. Swell heights average only 1.5-1.6m, with periods below 9 seconds, resulting in mainly choppy, low waves. The swell direction is overwhelmingly from the NNW, almost directly aligned with the shoreline — very little wrap and a lot of closeouts. Offshore wind frequency improves somewhat in July and August (42-43%), but with such weak, short-period swell, the quality suffers. This is the time for longboard cruises or a travel plan to the Southern Hemisphere.

December: Peak Consistency

December tops the charts for consistency and power. Average swell height is 2.1m, period 12.9 seconds — very powerful. The swell direction is the most varied of the year: NNW 31.7%, NW 27.9%, and a significant 12.0% from WNW, with 1.9% from west. This mix ensures the spot gets plenty of direct-angle swell alongside wrapping NW energy. Offshore wind frequency is 60%, the highest percentage of any month. The E wind (13.7%) and ESE (10.4%) are frequent, often light and offshore, smoothing the waves into clean, hollow lines. With the NAO index often negative in December, the storm track is aimed directly at the region. This is the month to plan your trip.
