Hey folks, Rusty here with a look at what's shaping up for Aoshima. It's a bit of a slow starter, so don't rush down there just yet. We've got a gap of a few days with nothing really worth paddling out for, but things start to show some life from next Monday.

The first real hope comes on the morning of Monday, July 6th. We're looking at a clean 1.3ft ESE groundswell with a long 18 second period. The combined wave energy is sitting at 144, so it's not pumping, but the session is rideable. The wind is a moderate offshore from the WSW, keeping the faces tidy. It's not a standout, but it's a start.

The energy really starts to build through the week, but unfortunately, the wind turns against us. From Tuesday the 7th through Thursday the 10th, we see the swell pumping up—reaching a solid 13.1ft by Friday the 10th with massive energy readings in the thousands—but it's mostly onshore or cross-onshore wind. The period is long, around 16-18 seconds, which is classic groundswell. For a reef setup like Aoshima, that long period can actually work really well if the direction is right, but the onshore wind is going to chop it up and make it a tough paddle. The huge 13.1ft swell on Friday is only for the experts anyway, and with those winds, it's a pass.

Now, the true standout window arrives on the weekend. The morning of Sunday, July 12th is the pick of the entire forecast. We get a clean 6.2ft SSE swell with a solid 12 second period. The combined energy is a solid 1023, and the wind? Absolutely glassy. Calm, offshore conditions. That means Aoshima's reef will be pristine, with smooth, well-shaped lines. This is the session to circle. It's a strong option for experienced surfers looking for good quality. Crowds are possible at Aoshima, so getting out early Sunday morning is the move.

Later that day and into Monday the 13th, the swell drops but stays fun. Monday morning offers another glassy session with a 3.6ft SSE swell (301 energy). Still clean and rideable. After that, the swell fades back to small, ordinary waves through the rest of the second week. The water temp is 78.3°, which is about 1.8° colder than usual for this time of year—nothing too crazy, just a touch cooler than average.

So, to sum it up: the first week has building swell but ugly wind. The one and only standout is the morning of Sunday, July 12th. Get your glass off and enjoy Aoshima clean.

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.
