The Lowdown

Right, gather round. Rusty here, lookin’ at the charts for the next couple weeks. Bit of a slow start, but there’s a few windows of opportunity if you’re patient.

The first week is a bit of a write-off, to be honest. We’re lookin’ at a stretch of poor surf conditions from Sunday the 16th right through until the end of that week. The wind is mostly cross-onshore or onshore, smashing up what little swell there is. The combined energy is weak, sittin’ under 300 (282) for the first few days, and the swell is tiny, runnin’ about 2ft to 4ft, with a short, weak period. It’s choppy, it’s messy, and it’s not worth paddling out for. Saturday the 22nd and Sunday the 23rd are a little better with a bit more size, but the wind is still not right, and the conditions are still poor. The water temp is about 82°F and, well, it’s normal for the time of year, nothing to write home about.

Then things start to get interesting. Monday the 24th of August we see a new pulse of groundswell fillin’ in from the SSE. It’s got a long period of 16 seconds and the combined energy jumps to 1234 (moderate). The swell is 5ft in the morning, up to 6ft in the afternoon. The wind is still a bit of a cross-on, but it’s gentle. It’s still marginal, but it’s a sign of what’s comin’.

Now, the standout. Look no further than Tuesday the 25th of August at Akabane Long Beach. That morning, it’s gonna be magic. We’re talkin’ a solid 8ft of clean SSE groundswell, period of 16 seconds, and the combined energy is 2798 (strong). The wind is a glassy light NNW, practically offshore. This is excellent surf. The water is about 82°F, which is normal for this time of year. The waves will be a bit powerful for beginners, but for the experienced crew, this is the session to circle. The swell is over 8ft by the afternoon, so it’s definitely for experts only then. Crowds are often a thing here, so be ready for some company.

The swell stays big through Wednesday the 26th, with 8ft sets, but the wind swings cross-onshore, so the quality drops. Still a lot of energy in the water (3213), but it’s gettin’ a bit messy. Thursday the 27th is just too big. The swell hits 10ft in the morning, with a massive 4685 combined energy, and the wind is howlin’ cross-shore. It’s a kite-surfing show, not a paddle-out. Friday the 28th and Saturday the 29th are the same story – big, messy, and blown out with strong winds and risk of thunderstorms.

The tail end of the forecast sees a drop in swell but a return to clean conditions. On Monday the 31st of August, the swell drops to 7ft from the ESE, with a short period of 7 seconds. But the wind is offshore from the NNW, then goes glassy in the afternoon. The combined energy is moderate (663 to 738). It’s a good option for the smaller board, cleaner waves, and a nice way to finish the forecast period.

So, to sum it up: the first week is a right-off. Tuesday the 25th is the absolute best on offer. That’s the one. The end of the month cleans up nicely for a smaller, more relaxed session.

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. Our Akabane Long Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Akabane Long Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
