The Lowdown
Alright, Rusty here. Let’s talk about what’s coming at Akabana Long Beach.
We’re looking at a slow start with no real action for the first few days. Thursday the 20th and Friday the 21st are flat and ugly - tiny little waves with poor winds. Saturday the 22nd morning will give you a clean 3ft wave from the SSW, but it’s weak and just average. Sunday the 23rd morning goes glassy with a 2ft SSW swell, but it’s still just a dribble.
Then Monday the 24th of August brings a change. A SSE groundswell rolls in at 5ft with a nice long 16-second period. The combined energy is moderate at 2409. The morning has a light cross-onshore breeze, so the surface isn’t perfect, and the wave call says the tide could be tricky. If you get the tide right, there’ll be some lined-up, rideable waves. Water temp is normal for this time of year at around 80°F.
The real standout is Tuesday the 25th of August morning, but it’s for experienced big-wave surfers only. The swell pumps up to 12ft from the SSE with that same 16-second period. The combined energy is very strong at 6936, and the wind is perfectly glassy. With that period and no wind, the waves will be clean, powerful and big. The forecast notes this swell is probably too big for the break, so unless you know how Akabane handles big water and you’ve got the skills, stay on the sand. The afternoon grows to 13ft but the wind goes cross-onshore.
From Wednesday the 26th onward, it’s a total mess. Heavy rain, strong onshore winds, and huge windswell coming from the east. The combined energy stays high, but with gale-force winds and rough chop, the ocean is blown out. This looks way better for kite surfing than paddle surfing. Even when the wind turns clean again on Friday the 28th, the waves are too messy to be any good.
So to sum it up: your best bets are the early morning of Monday the 24th if you can handle the tide, and Tuesday the 25th morning for the big, glassy, expert-only bombs.
Rusty, out.

Information about the Akabane Long Beach Surf forecast
The above surf forecast table for Akabane Long Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
