The Lowdown
Alright mates, Rusty here with the lowdown on Aoshima. The next week and a half is pretty grim, so don’t rush. The good stuff comes in the second week for those holding out.
We’re starting with a big dry spell. For the first ten days or so, you’re looking at tiny surf, from about 0.7ft to 2ft. Most of the afternoons are blown out with cross or onshore breeze, but the mornings do go glassy. Still, the swell is too weak to bother with – energy readings are low, just single and low triple digits. The water temp is pretty normal for the season. You’d be better off doing something else.
Then, from Sunday the 2nd of August, a proper long-period east swell starts showing. Sunday morning is glassy with a little 2ft wave but a 16-second period, giving it a bit of punch (223 energy). But the real highlight is Tuesday the 4th of August. That morning is an absolute gem: a clean 8ft east swell with an 18-second period – that’s serious power (3376 energy). Dead calm wind, glassy as a lake. This is for experienced surfers only; it’s going to be pumping and mighty. The swell is slightly east of the ideal direction for the reef, but the size and period will make up for it. Circle this day.
Wednesday the 5th of August morning still has clean 6ft leftovers from that pulse (1699 energy), still glassy and excellent for the crew who know their way around bigger waves. The rest of the week fades nicely, with glassy 3ft to 4ft waves on Thursday that will be super fun on a longboard. It’s a proper wait, but the reward is a solid, short window of quality surf.
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.
