The Lowdown
G’day, Rusty here. Lookin’ at the charts for Aoura, and I gotta be straight with you – it’s a slow start, but there’s a proper monster hiding in the second week that’s got my heart racing.
Right now, we’re in a bit of a flat spell. The small stuff that’s showing from Thursday 13th through the weekend is just not worth paddlin’ out for. Tiny 2ft easterly swell, short period around 10 seconds, and cross-onshore winds messin’ it up. The energy is weak (85 to 180). It’s a write-off.
We’ve got a long gap with nothing worth mentionin’ until Monday 17th. Even then, it’s only marginal at best. The swell picks up a touch to 4ft, but the wind is still messin’ with it, and the energy (338) is only just gettin’ interesting. This pattern of small, choppy, onshore junk continues right through to Saturday 22nd. Honestly, if you’re desperate, you could look at Thursday 20th morning – the swell is 4ft from the SE with a short 8-second period, but it’s onshore wind and the call is marginal. Not one to get excited about.
Now, hold onto your board, because the real deal arrives Sunday 23rd August. This is the standout. The swell jumps to a solid 5ft from the ESE, and the period stretches out to a very long 16 seconds – that’s proper groundswell energy. The combined energy rockets to 1258 (strong). The wind swings around to a light cross-off from the NNE, and the conditions are described as clean. This is excellent for experienced surfers. Because the period is so long, this wave will be best at a reef, point, or river mouth where it can wrap in and hold its shape. It won’t be a beginner’s wave, but for anyone who knows their way around, it’s on.
Sunday afternoon gets even better. The swell builds to 7ft from the same ESE direction with a 17-second period, and the wind goes glassy. The energy is up to a massive 2431 (strong). That’s the kind of session you dream about. Expect long, clean lines with heaps of push.
Monday 24th is for the hardcore crew only. We’re lookin’ at a thumping 10ft swell with 17-second period and glassy conditions in the morning. The combined energy is insane at 5124 (very strong). This is exceptional surf for expert surfers. Aoura is an exposed reef break, so this is serious – big, powerful, and not for the faint-hearted. The afternoon turns a bit cross-onshore, so get in early.
The quality holds through Tuesday 25th and Wednesday 26th, with swell staying around 10ft to 12ft, but the wind gets a bit messier, turning cross-shore or onshore. Still, Wednesday 26th morning cleans up again with glassy conditions and a 10ft swell at 14 seconds. That’s another excellent window for experienced surfers.
Thursday 27th morning still has good leftover energy – 7ft, 13-second period, glassy – but it’s a drop-off. From there, the swell fades fast, and by Friday 28th, we’re back to flat, tiny leftovers.
So, the two true standouts are Sunday 23rd August (especially the afternoon) and Monday 24th August morning. That Sunday afternoon session with 7ft, 17-second period, and glassy conditions is the one to circle on the calendar. Aoura is an exposed reef, so with these long-period swells, expect consistent, well-shaped waves – and because it’s an advanced spot that’s inconsistent and often crowded, get there early to beat the pack.
Water temp is 84°F, which is bang on average for this time of year. No worries there.
Rusty.

Information about the Aoura Surf forecast
The above surf forecast table for Aoura provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Aoura can be found by selecting the local surf guide option on the grey menu. Our Aoura 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 (Aoura) 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 Aoura 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.
Aoura is 9 km (6 miles) from Nichinan. If you plan a holiday in Kyu Shu, look for hotels and other accommodation in Nichinan. Nichinan has rooms for a wide range of budgets as well as car hire and transport links.
