Alright, let’s get into it. This is the Aoshima outlook.

First thing you need to know: Aoshima is a reef break, exposed to the swell, and it’s a fairly consistent spot. It does get crowded sometimes, so keep that in mind. The water is running a bit colder than normal for this time of year, sitting at 79°F.

We’re looking at a bit of a slow start, but the real standout is coming up this Sunday morning, July 12. That’s where the magic is. We’ve got a solid 7ft swell out of the SSE with a 13-second period, which is a nice long groundswell. The combined energy is pumping hard at 1814, so there’s plenty of power in the water. The wind is a light cross-off from the south at 6 mph, keeping things clean. This is excellent surf for experienced surfers. If you’ve got the skill, this is the session to aim for.

The wind holds for Sunday afternoon, but it picks up to 16 mph from the SSE, turning it cross, and the quality drops. Monday morning, July 13, is a total glass-off with the wind swinging to the west at 3 mph, and we’ve got a 4ft SSE swell at 11 seconds. The energy is moderate at 441, but the glassy conditions will make it look better than it is. That afternoon sees a slight increase in swell to 5ft, and the wind is light cross-off from the south, so it stays clean. Not a standout, but a solid option.

From Tuesday, July 14, through to Friday, July 17, the surf drops right off. We’re looking at tiny waves, mostly under 3ft, with poor to ordinary conditions. The energy is weak, and the winds are mostly cross-on or onshore. There’s a gap of several days with no real recommendations here.

Saturday, July 18, and Sunday, July 19, see a spike in size, but the wind is onshore from the ENE and E, blowing at 9-12 mph. Sunday morning has an 8ft E swell at 11 seconds, energy over 2921, and it’s strong, but with onshore wind and the risk of thunderstorms, it’s going to be a messy, blown-out mess. That kind of size and wind at a reef is not a good look for paddle surfing. It might be more interesting for kite surfing.

The rest of the week into the end of July is mostly small, with poor winds and low energy. The one bright spot is Friday morning, July 24, when the wind goes offshore from the WSW at 6 mph, and we’ve got a 3ft E swell. It’s clean, but tiny. Not worth getting too excited about.

Overall, the only true standout is Sunday morning, July 12. That’s your best bet. The rest of the 16 days is a mix of small, messy, or blown-out conditions. Stay patient.

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.
