Conditions at Moruya Breakwall in September

September: Spring Re-Awakening

September is a true shoulder month. Ideal wind slips to 36 percent and average period drops to 8.5s, but the swell direction mix actually improves for the breakwall: ENE (15 percent), E (12 percent), ESE (12 percent) and NE (8 percent) combine for 47 percent, while the south quadrant remains active. Wave heights average 3.5ft (1.1m), with plenty of 2-3ft (0.5-1m) and 3-5ft (1-1.5m) waves. The wind story starts to change: the northern quadrants are trending up - NNE 10 percent, NNW 13 percent - and the true offshore westerly sector drops to around 22 percent. Onshore NE-E wind is still modest, around 16 percent, but the sea breeze is returning with the spring warmth. Air temps are mild at 13.2°C, water temp at 15.9°C, and precipitation is low at 1.64 mm/day. The best September surf usually comes from a slow-moving Tasman low delivering clean E/ESE swell ahead of a cold front, followed by a WNW offshore clean-up.
