September: Late Season Size, Fickle Winds
September is a month of mixed signals. The average swell height is still up at 1.3m (4.5ft) and the period is a solid 10.5s, but the ideal wind percentage sinks to 41%. The swell direction shows an increasing influence of ESE at 16.2% alongside S (29.3%) and SSE (26.5%), meaning more of the energy is tied up in shorter-period, trade-wind-driven surf. That said, the 1-1.5m (3-5ft) class is the largest, with 1.5-2m (5-6.5ft) present as well, so there is no shortage of waves. The problem is often the texture: the E/ENE trades are stronger, and a mid-latitude low can throw S/SE winds on top of the swell. When the N/NNW offshore lines up, it still holds good size, but you need to pick your sessions. Water temp is now at its annual low of 20.5°C, air temps average 21.7°C, and rainfall begins to increase to 3.0mm/day.
