The Lowdown
Rusty here again, switching to feet and miles for you. A look at Aoshima, and it's a slow start before some serious size turns up.
First week is mostly flat. Monday the 27th of July has a tiny 2ft ESE swell and onshore wind, so nothing doing. Tuesday the 28th shows 2ft ESE swell with glassy conditions in the morning but still weak. Wednesday the 29th through Saturday the 1st of August stays small with 1ft to 2ft ESE swells in glassy or light winds, but just no power. Sunday the 2nd of August is flat.
Monday the 3rd of August finally shows some life: 4ft ESE swell with a 14-second period and energy at 547. Wind is cross-onshore which spoils it a little, but that long period means there's proper groundswell in the water. Tuesday the 4th builds to 6ft ESE with a 16-second period and energy of 1779.
Wednesday the 5th of August is the real standout. Morning brings 8ft ESE swell, 18-second period and energy at 4275. Glassy wind from ENE at 3 mph. That's expert territory and clean. The very long period means the waves will have plenty of push, but at a beachbreak they can section off. Still, it's the best on offer. Thursday the 6th has 10ft ESE, 16-second period, glassy in the morning with energy at 4793. Also a cracker.
Friday the 7th of August is massive with 13ft to 15ft ESE swells and energy up to 12494. Winds are not ideal but the power is huge. Saturday the 8th is enormous – 25ft ESE, 19-second period, glassy, but way too big for this spot with energy at 42106. Sunday the 9th drops to 16ft from the E with glassy wind; exceptional for experts. The best window runs from Wednesday the 5th through Sunday the 9th, with the cleanest mornings on the 5th, 6th, and 9th.
After that, Monday the 10th of August goes back to 6ft E swell with cross-onshore wind, then Tuesday the 11th cleans up with 4ft E swell and glassy conditions.
Water temperature is 85°, just 1° above normal – about average for the season. Aoshima can have a crowd around sometimes, so those mid-week glassy mornings will be the ones to aim for.
The call is Wednesday the 5th and Thursday the 6th of August mornings. That's where the magic is.
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.
