September: Late-Winter Swell With a Side of Spring
September keeps the winter swell pumping as the season slowly transitions. Average height remains at 1.9m (6.2ft) with a 12.9s period, and the southern swell window continues to deliver. SSW accounts for 73.3% of the energy, due S for 18.6%, and SW for 2.6%. The S component is actually at its highest of the year, adding a little more variety to the mix. About 78% of all waves are in the 1.5-2.5m (5-8ft) range, making September one of the most consistently solid months of the year.
The wind pattern is stubborn: S at 38.9%, SSW at 37.7%, SW at 15.7%, and ideal offshore wind at just 2%. With the ocean still cold at 15.2°C and air temperatures around 16.8°C, it feels like full winter. The good news is that the storm track is still active, so the swell rarely stops. Look for the brief windows of light E/NE wind or early morning glass to get the best out of this late-season grind.
