Conditions at Warroora Station in September
September: Big but Less Clean
September holds the peak wave height at 1.7m (5.6ft) and the period remains long at 13.8s. The swell is even more SW-dominant, with 64% from SW and 26% from SSW, and a significant share of the energy sits in the 1.5-2.5m (5-8ft) range. This is a powerful month on paper - the Southern Ocean is still firing, and the beach will see consistent, heavy groundswell.
The catch is the wind. Ideal E/ESE/SE/SSE flow is only 16%, with strong S and SSW winds combining for nearly 50% of observations. These cross/offshore southerlies can put texture on the face and make the lineup tricky. Air temps begin to warm at 21.1°C, water temp bottoms out at 22.1°C, and it is the driest month of the year at 0.13mm/day. If you are skilled at reading shifting winds, September is a sleeper; otherwise, it is a transitional month.
