The Lowdown

Alright folks, Rusty here with a look at what we’ve got on the cards for Aoshima over the next couple of weeks.

Right off the bat, things are pretty quiet for the next week or so. We’re looking at a long stretch of nothing special until we get toward the end of the month. The first week is a bit of a write-off, with small, weak swell and wind directions that just aren't doing us any favours. You'll be waiting a while for anything that gets the heart rate up.

The standout in this whole window is without a doubt Sunday morning, the 23rd of August. That’s the one you want to keep an eye on. We’ve got a solid 7ft swell pushing in from the SSE, and the wind is looking glassy with that ENE breeze. This sets up some clean waves for experienced surfers – it’s a bit of a beast, so you’ll want your skills dialled in. The wave energy is strong at (1818), and it's a good, long period groundswell at 11 seconds, which will see Aoshima (reef) offering up some proper lines. The prize is worth the patience.

Before that, there’s a slight tease on Tuesday morning, 11th August. We see a small 4ft easterly swell with glassy conditions. It’ll be clean, and for a beginner-friendly spot like Aoshima, that makes for a fun, manageable session, even if the energy is only moderate (577). It’s not the big show, but it's the only real quality window in the first week.

Later on Saturday the 22nd, the swell starts to ramp up with 7ft to 7ft from the SSE, but the wind is a bit messy so it’s hard to get excited just yet. Then you get that prime Sunday morning. By Sunday afternoon on the 23rd, the wind shifts and the quality drops off. We also see a bit of a pulse around Monday the 24th, but with the wind onshore, it's more of a windy, choppy mess for most.

The water temp is sitting right around 84°, which is pretty much bang on average for this time of year, so no wetsuit needed.

So, to wrap it up – the early days are lean, but hold out for that Sunday the 23rd. That’s the day.

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.
