Table - best surf conditions forecast for Aoshima over the next 16 days.
Alright folks, Rusty here with a look at the local stretch. We’ve got some solid energy coming through for Aoshima, a reef setup, but don’t get too excited just yet. Clean conditions are going to be the real prize here, not just raw size.
The big story for Aoshima is the giant pulse of swell hitting on the 19th (Sunday). We’re talking a powerful 12ft of SSE swell with a long 17-second period, pumping out a massive 6586 (combined energy). That is serious, heavy water. But the wind gods are not on our side – it’s a cross-onshore chop. This might be a show for the experts only, because anything over 8ft is for the crew with big cojones. The period is very long, so the setup might feel a bit straight for a beach break but as a reef, it could hold its shape. Still, the wind will make it a battle. This isn’t the best of the window.
The real standout, the one to circle on your calendar, is the morning of Monday the 22nd. The swell drops to a much more manageable 4ft from the ESE, with a decent 9-second period. The combined energy is a moderate 337. But the kicker? The wind is glassy – dead calm. That means smooth, clean faces and no ripples. For a reef break like Aoshima, glassy conditions are pure magic. The direction is a solid match for the optimum SE swell direction, so expect nice lines. The water is sitting at 79°, which is a bit colder than normal for this time of year, so maybe a light spring suit if you feel the chill.
Right after that, the Thursday morning the 23rd is another good look. A very similar 4ft ESE swell (421 combined energy) with glassy conditions again. Clean surf on offer.
After the big 19th, the surf settles down. From the 15th to the 18th, we have a couple days of tiny, weak waves (under 3ft) that aren't worth paddling out for. Then, following the 23rd, things get small again and more marginal, with onshore winds picking up through the second week.
The Best of the Bunch: The top pick is Monday morning the 22nd. You’ve got a fun 4ft of groundswell from the ESE, glassy conditions making it super clean. This is the session to be on it. Aoshima on a glassy 4ft with that direction (optimum SE) will be user-friendly for most levels and not too crowded if you are early. The morning of the 23rd is a very close runner-up for similar conditions.
All in all, wait for that glassy window around the 22nd and 23rd. That’s where the magic is.

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.
