The Lowdown
Alright, mates, Rusty here. Let’s be real about the next couple of weeks. The ocean’s gonna be a mess, and you’re gonna be watching from the sand. The first couple of days are flat and crumbly, nothing worth paddling out for.
There’s a tiny glimmer on Sunday, August 2nd. A clean 2ft wave with glassy conditions in the morning – it’s small but it has some push from a long-period east-southeast swell. You might snag a couple of fun ones if you’re keen, but it’s more about the peace and quiet than the waves themselves. Don’t get too excited; it’s not gonna last.
Then the whole thing just turns to shambles. From Monday, the swell starts pumping, but so does the onshore wind. By Wednesday and Thursday, we’re looking at 15 to 25 feet of raw, angry ocean, blowing 25-30 mph plus. That’s not a surf forecast; that’s a storm warning. The energy is massive – readings of 34386 and 63484 – but it’s all power and no form. It’s too big for a reef like Aoshima, and it’s just not safe. You’d be a fool to go out in that.
The weekend after that is still blowing hard, with 10-12ft of messy, lumpy surf. Water’s warm, but that’s the only positive. This is kite-surfing territory, not a paddle-out.
The second week is a long, drawn-out decline. The swell fades, but the wind stays onshore and it all just gets mushy and weak. There might be a tiny window on the 11th with 6ft of east swell, but it’s cross-shore and messy, not worth the effort. The rest of the week is just small, blown-out dribble.
Honestly, there’s nothing on offer here that gets the heart pumping. It’s a blank run. The only half-interesting session is that small clean one on Sunday morning, and that’s saying something. We need a change in the weather pattern, a shift in the wind, something. As it stands, keep the board in the car and save your energy.
Rusty.

Information about the Aoshima Surf forecast
The above surf forecast table for Aoshima provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Aoshima can be found by selecting the local surf guide option on the grey menu. Our Aoshima 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 (Aoshima) 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 Aoshima 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.
Aoshima is 14 km (9 miles) from Miyazaki-shi. If you plan a holiday in Kyu Shu, look for hotels and other accommodation in Miyazaki-shi. Miyazaki-shi has rooms for a wide range of budgets as well as car hire and transport links.
