September: Prime Time at Ditch Plains
September is the best month of the year for Ditch Plains. The average swell height rises to 3.3ft (1.0m), and the average wave period jumps to 7.7s, the highest of any month, a sign of genuine longer-period swell from tropical cyclones and early fall extratropical lows.

The wind regime is more mixed: SW (13.3%) and SSW (10.2%) still bring sea breezes, but ENE (7.9%), NE (6.6%) and NNW (7.6%) keep things varied, and 15% of the time the wind is ideal.
