The Lowdown
Alright folks, Rusty here. Let’s have a look at what Aoura’s got cookin’ for the next couple of weeks. It’s a bit of a mixed bag, but there’s a day or two worth gettin’ excited about if you’re patient.
Right off the bat, the water is sitting at 84°F, which is pretty much bang on average for this time of year – no surprises there.
The first week is a slow burn, honestly. We’ve got some swell moving through, but the wind is just not playin’ ball. Sunday the 23rd and Monday the 24th are a write-off with poor surf conditions and light cross-shore chop. The wave energy is weak to moderate at best (144 to 152) on Sunday, and then Monday morning it picks up to 404, but still no good.
Tuesday the 25th is where things start to look interesting. We’re lookin’ at a solid 13ft swell from the SE, with a long 16-second period – that’s proper groundswell energy. The energy readings are massive (7988 to 7793), but the wind is a stiff cross-shore at 15-18 mph, which is gonna put a lumpy chop on it. That’s a lot of power for a reef break, so this one is strictly for the advanced crew. Expect it to be a handful, and with long-period swell like that, it’ll be better if you can line up your takeoff. It’s a bit of a beast, but if you’re experienced, Tuesday morning could be a wild ride.
The rest of that week and into the weekend gets messy again. Wednesday and Thursday are hammered by fresh onshore winds and rain, with the swell dropping from 13ft down to 6ft. The energy tanks (from 6837 down to 587), and it’s just not worth paddlin’ out for the average surfer. By Saturday the 29th, we’re back to tiny, weak 2ft waves with light cross-shore winds – energy is barely a whisper (105 to 107). Basically a flat spell.
Now, lookin’ into the second week, there’s a glimmer. Monday the 31st of August and Tuesday the 1st of September see a return of 5ft to 7ft swell from the SE, with periods around 12-13 seconds. The wind is moderate cross-shore, so it’s not perfect, but the energy is moderate (680 to 1940). It’s not a standout, but it’s the best we’ve got in that stretch. The morning of Monday the 31st has a cross-offshore wind, so it’ll be clean, but still only marginal.
After that, it’s a long, sad run right through to the end of the forecast. From the 2nd of September onwards, it’s all poor surf conditions with onshore winds, rain, and a severe gale on the 5th of September hittin’ 53 mph from the SE. That’s not surf, that’s a survival mission. The last few days on the 6th and 7th of September show a little 4ft to 5ft swell with clean cross-offshore winds, but the energy is weak (180 to 442) and it’s only marginal.
The only real standout here is Tuesday the 25th of August. That 13ft SE groundswell with a 16-second period is a powerful, legit swell for Aoura. The wind is gonna be a bit messy, but for the high-level crew, that’s the day to circle. Just be warned, it’s a big, long-period swell on a reef break – not for the faint-hearted.
Honestly, for most of the window, you’re better off waitin’ for a better forecast. The setup with that much wind and swell on a beach/reef break might actually be more interesting for the kite surfers than us paddle folk.
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.
