The Lowdown
Alright, grab a coffee and listen up. This is a long-range look at Aoura, and honestly, we’ve got a bit of a mixed bag. The first week is pretty bleak, but there’s a serious window of opportunity at the end of the month that’s got my attention.
First up, Aoura is a reef break. It’s an advanced spot that’s inconsistent, so it doesn’t just switch on whenever. The water temperature is sitting at 84°F, which is about normal for this time of year, so no drama there.
The first few days are a write-off. From Thursday, August 20th right through to the middle of the following week, the swell is tiny and the wind is rubbish. The wave energy is weak (95), and we’re looking at surfable waves but very ordinary conditions—meaning it’s small, bumpy, and not worth paddling out for. The forecast score is low, so save your energy.
Then things start to get interesting. On Sunday, August 23rd, the afternoon shows a pulse of energy coming through with a 16-second period. The combined energy jumps to 268 (moderate), but the wind is cross-onshore and choppy, so it’s only marginal. The real shift happens on Monday, August 24th, when the swell builds to 6 ft in the morning, with a 17-second period and a combined energy of 1777—that’s strong wave energy. The wind is cross-shore, creating a slight chop, so it’s still not clean, but the size and period are there. The set-up is more suited to reef breaks like Aoura, but that cross-shore breeze will keep it from being perfect.
Now, the standout. Tuesday, August 25th, is the one to circle. The morning brings a solid 13 ft swell from the ESE, with a 17-second period, and the wind is a light cross-off from the NNE at 19 mph. The combined energy is a massive 8254, and the wave comment says “clean.” This is big, powerful, and well-shaped. The wind is creating clean conditions, which is a major positive. The afternoon keeps it pumping: 15 ft, 16-second period, cross-off wind at 25 mph, and 10783 energy. This is expert territory—too big for beginners, and even for advanced surfers, it’s going to be a handful. The direction is ESE, which is close to the optimum NE swell direction for Aoura, so it’s working.
However, Wednesday, August 26th, is a write-off again. The wind swings to gale-force onshore, blowing the whole thing out, and the swell drops. The rest of the week stays messy with onshore winds and small, choppy surf. The energy dips back to moderate (633) and weak (303) by Friday, August 28th.
The following week, from August 30th onwards, sees a return to smaller, more manageable swell. The energy is moderate (630), with 6 ft from the ESE on Sunday, August 30th, but the wind is cross-onshore and fairly choppy. The best chance in that second week is on Tuesday, September 1st, morning: a clean 4 ft swell from the ESE, with a light cross-off breeze from the NNE. The energy is 256, but the “clean” comment makes it a decent option for a small-wave session.
Between the big swell on Tuesday, August 25th, and the smaller stuff the following week, there’s a gap of poor conditions, so don’t expect a consistent run.
Overall, the big Tuesday window is the true standout. It’s big, powerful, and clean, but it’s also a long-range call, so keep an eye on the forecast. For the rest of the period, it’s a waiting game.

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.
