Conditions at Jelly's Point in September

September: First Real Pulse

September is where Jelly's Point starts to wake from its summer slumber. The average height is still modest at 2ft (0.6m), but the average period jumps to 9.9s and the swell distribution gains more N, NNE and NNW energy. ENE contributes 31%, NE 21%, E 19%, and NNE 9%, with the rest split between ESE/SE and the northern quadrants. Wave heights cluster around 2-3ft (0.5-1m), yet the longer-period lines carry more push than the mid-summer mush. Wind is still reasonably good - 39% ideal - with S (15%), SSW (10%) and SSE (11%) keeping things clean. With the tropical cyclone season churning in the West Pacific, September can occasionally throw a 3-5ft (0.9-1.5m) N/NW groundswell your way. It's a shoulder month with real potential. Water temperature is 29.4°C and rainfall is 6.0mm/day.
