Coxos - surf spot statistics

Best Surf Season (October - March)

The North Atlantic roars to life during the autumn and winter months, delivering consistent, powerful swell from the northwest to west quadrants. Combined with favourable offshore winds from the east, Coxos lights up with long-period, hollow waves. Average swell heights range from 2.0m to 2.6m with periods averaging 11-13s, providing epic conditions for experienced surfers. The winter months (January-February) see the most consistent swell, though storms can bring strong westerly winds, requiring careful timing.

Fair Surf Season (April - May)

As the North Atlantic storm track begins to weaken, swell heights and periods decrease. April still offers decent swell (avg 2.0m, 11s) but wind becomes more variable with increasing north winds. May sees a drop to 1.7m and 10s periods, with more days of onshore flow. Surfable waves are still present, especially on days with easterly winds, but quality is inconsistent.

Low Surf Season (June - September)

The summer months are characterised by small, weak swell and persistent northerly winds that create choppy, onshore conditions. Average heights fall to 1.4-1.6m and periods drop to 8-9s, resulting in slow, gutless waves. The wind is ideal less than 20% of the time, mostly during occasional easterly wind events. While the swell direction is often from the NW, the lack of power and poor wind make for challenging surfing. Occasional south swells can offer relief, but generally, this is a time for rest or rope climbing.

April: Declining Swell, but Still Solid

April sees a notable drop in average swell height to 2.0m and period to 11.1s, moving into the fun, good, solid category. Swell directions shift, with NW (28.0%) and WNW (21.3%) still top, but NNW increases to 20.0%, indicating more swell from the north. Ideal wind drops to 17% as the subtropical high builds, bringing stronger N winds (22%) and persistent NW flow (9.6% from NW). While the average period is still powerful enough for solid waves, the northerly winds tend to create windswell on top of the groundswell. When easterlies blow, Coxos can turn on with clean, reeling lines. April is a shoulder month — good days exist but require more patience and a keen eye on the charts.
