The Lowdown
G’day, Rusty here again, this time in feet, miles per hour, and Fahrenheit. Let’s run through the same gig for Akabane Long Beach. First few days are a write-off – onshore junk, thunderstorms, and cross-chop. Nothing to bother with.
Thursday the 17th of September is the first real look. Glassy conditions in the morning, with a 5ft ESE swell. Short period at 7 seconds, so it’ll be a bit lumpy and crumbly, but energy is moderate (364) – enough for a fun little session on a bigger board. Water temp is 80°, which is typical for this time of year, no big anomaly. Crowds pop up often here, so don’t expect solitude.
Friday the 18th is the standout. Morning kicks off with 5ft E swell and a light offshore breeze, clean, with moderate energy (371). The afternoon is the real prize: glassy wind, 5ft E swell, 9-second period, and energy climbing to 665 – solid, fun, clean waves. That’s the session you want to be in the water for.
Then things go big. Saturday the 19th and Sunday the 20th bring a heavy SE groundswell – 12ft to 13ft with a long 14 to 15-second period, and combined energy in the thousands (5799 to 7712). That’s well over 8ft, experts only, and probably too much for Akabane Long Beach, even with clean offshore winds. Monday the 21st pushes even bigger at 16ft SSE – massive, not for most.
After that, it’s a long dry spell. From Tuesday the 22nd of September through the end of the month, swell drops under 3ft, winds crank up, and conditions are poor. There’s a little flicker on Monday the 29th of September with a clean 5ft ESE swell and offshore wind, but at only 6 seconds period, it’s weak and won’t hold.
Best bet: Friday the 18th afternoon – glassy, chest-to-shoulder-high E swell, clean lines, and good energy. Thursday the 17th morning is the backup for a smaller, glassy session.

A general guide to surfing at Akabane Long Beach can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Akabane Long Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
