The Lowdown

Alright, Rusty here. Let’s have a look at what’s on the table for Akabane Long Beach over the next couple of weeks. Grab a coffee, because it’s a bit of a mixed bag.

Right out of the gate, it’s not looking pretty. We kick off Wednesday the 12th of August with rain showers and a strong cross-onshore wind from the ESE at 25 km/h, bumping up to 40 km/h in the afternoon. The swell’s there – around 3 ft from the SSW with a 10-second period, but it’s so chopped up and messy you wouldn’t paddle out. The combined swell energy is moderate at 317, but it’s a write-off for surfing.

Thursday and Friday are more of the same: cross-onshore winds, thunderstorms, and small, weak swell. The water temp sits at a warm 82°, which is about average for this time of year, so at least you won’t need a steamer if you’re desperate. But honestly, Friday morning is the first time we get a tiny window – a 3 ft Easterly swell with a light breeze, but it’s a cross-shore, and the conditions are only marginal. Not worth getting wet for.

We then hit a long, flat stretch. Saturday the 15th through to Monday the 17th is just poor: onshore winds, tiny swell, and that’s that. The waves are either too small or too wind-affected.

Now, here’s a glimmer. On Tuesday the 18th of August, early morning, we get a glassy session. The wind drops to almost nothing – 5 km/h from the ESE, glassy conditions. The swell is tiny, only 2 ft from the East with a 9-second period, and the combined energy is low at 111. It’s surfable, but you’ll be on a longboard or a funboard, working for every little bump. It’s very ordinary, but it’s the cleanest we get for days.

After that, it’s back to poor and windy through to the 20th. Then on Thursday the 20th and Friday the 21st, we get a couple of cleaner mornings with a light cross-offshore breeze from the WNW. The swell picks up a bit – Friday the 21st morning shows 4 ft from the SW with a short, weak 6-second period. The combined energy is moderate at 203, but it’s still a junky period. Clean, but the waves lack punch.

Hold on, Saturday the 22nd of August gets interesting. The morning brings a fresh WNW wind at 30 km/h, which is cross-offshore and clean. The swell is 4 ft from the SSW with a 10-second period, and the combined energy is moderate at 275. This is the best-looking window for a proper surf in the first week. The wind is strong but offshore, so it should hold the waves up. For an exposed beach break like this, that offshore flow is a big deal. Still, with that period, expect longer lulls between sets, so pick your moment.

Then it fades again. From Sunday the 23rd onward, it’s back to small, weak, and onshore. We get a very late surprise on Thursday the 27th of August: glassy conditions in the morning with a 3 ft Easterly swell, and then by the afternoon, it’s glassy again with a 5 ft Easterly swell at 8 seconds and strong combined energy at 487. This is the standout of the whole run – clean, punchy, and with that combined energy jumping into the strong range. For a beach break, that short period will keep the waves crumbly and fun, not too straight. If you can wait that long, Thursday afternoon looks like the best surf we’ll see.

Summing it up: the first week is almost a write-off. Tuesday the 18th offers a tiny glassy session, Saturday the 22nd a clean but wind-strong morning, and then the real prize is Thursday the 27th of August afternoon. That’s your best bet. It’s a long wait, but sometimes that’s how it goes.

Rusty, out.

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.
