The Lowdown
G’day, Rusty here. Look, I’ll be straight with you—this stretch at Akabane Long Beach is a bit of a mixed bag for the next couple of weeks, with a lot of average to poor days and only a few windows that might get you excited. First up, the water temp is sitting around 81°, which is pretty normal for this time of year, so no need to worry about a wetsuit.
The surf kicks off on Monday, 10 August, but honestly, it’s a write-off. You’ve got a 4ft swell from the ESE with a 12-second period, but a strong cross-onshore wind from the south at 16 mph is messing it right up. The combined wave energy is moderate (885), but the conditions are just poor—choppy and blown out. Not worth paddling out.
We get a slight reprieve on Tuesday, 11 August. The morning looks clean with a cross-offshore wind from the NW at 12 mph, and the swell holds at 4ft from the east (11-second period). The combined energy drops to a moderate 562. It’s still a marginal call, but the clean conditions make it the first real chance for a session. The afternoon is similar, though the wind swings to the west. Still, it’s a surfable day for the intermediate crew.
Wednesday, 12 August, is a mess again. The morning sees a strong cross-onshore wind from the east at 25 mph, with 4ft swell and moderate energy (526). The afternoon gets worse—wind picks up to 28 mph, and the swell jumps to 6ft, but with a short, weak 6-second period. The energy is still moderate (414), but the strong winds and messy conditions make this a no-go. Honestly, with that setup, it looks more interesting for kite surfing than paddle surfing.
Thursday, 13 August, through to the end of the first week stays poor. The swell drops to 2ft–3ft from the SSW, with cross-onshore winds. The energy is low (189–241). It’s small, choppy, and not worth your time.
Now, here’s a standout to keep an eye on. Friday morning, 14 August, is a beauty. The wind goes glassy—dead calm from the NNE at 3 mph—and the swell is a clean 3ft from the east with a 10-second period. The combined energy is low (247), but those glassy conditions will make the waves super clean. It’s a small morning, but for a log or a longboard, it’s about as good as it gets in this run. Expect crowds to be possible, as it’s often busy here.
The following days are a slog. From Saturday, 15 August, through to Monday, 17 August, the swell hovers around 3ft–4ft, but the winds are mostly cross-shore or onshore, keeping the quality marginal to poor. The combined energy stays moderate (267–470). The only glimmer is Sunday, 17 August, morning, which has a risk of thunderstorms, a light cross-shore wind, and a 4ft easterly swell—but it’s still a marginal call.
The second week, from 18 August onward, is pretty ordinary. The swell drops to 1ft–3ft, with short periods (8–10 seconds), and the energy is weak to low (74–202). The winds are mostly cross-onshore or onshore, with a few glassy mornings. On Wednesday, 19 August, and Thursday, 20 August, you get a couple of glassy mornings with 2ft swell from the south, but the energy is very weak (74–86). They’re surfable but very ordinary.
The best of the second week looks like Sunday, 23 August. The morning has a glassy cross-offshore wind from the north at 3 mph, and a 3ft swell from the ESE with a 10-second period. The combined energy is moderate (202). It’s clean, and while it’s small, it’s a proper window for a fun session. Keep in mind that longer-period swell (13 seconds) pops up on Monday, 24 August, but it’s only 1ft, so it’s more of a ripple than a wave.
Overall, the standout is Friday morning, 14 August, for the glassy conditions and clean 3ft easterly swell. The other decent option is Sunday, 23 August, for a similar small, clean morning. The rest of the 16-day window is mostly a write-off—lots of cross-wind slop, small waves, and poor conditions. It’s a classic summer lull for this stretch, so don’t hold your breath for anything firing.
Rusty.

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.
