The Lowdown
Alright, this is Rusty. Let’s have a look at what’s cookin’ at Aja. It’s a real mixed bag and it’s gonna test your patience.
Honestly, the next week and a half is a write-off. We’ve got a massive gap here with no real surf. The first decent window doesn’t open up until around September 8th. For nearly two weeks, we’re lookin’ at a lot of wind, thunderstorms, and flat spells. The swell that does show up is mostly junk. Aja is a reef break exposed to the north, and the conditions just aren't lining up for a paddle.
That changes on Tuesday September 8th. That morning, the wind goes glassy, with a clean 5 ft swell out of the east, with a period of 11 seconds. That’s a proper groundswell, and the combined energy is solid at (541). It’s got some grunt, but it’s not too big for an intermediate surfer. Water temp is sitting at 83°, which is about average for this time of year. The afternoon keeps it glassy, with the same size and direction swell. This is the standout window in the whole outlook. The reef should handle that long-period east swell nicely.
Wednesday morning on September 9th stays clean, but the swell drops to 4 ft, and the energy pulls back a touch (407). Still a good wave, but nothing like the day before.
So, bottom line: sit on your hands, wait for September 8th. That Tuesday is your best shot at Aja, with clean, glassy conditions and a solid east swell. You might see a few others out there on that day though.
Rusty.

Information about the Aja Surf forecast
The above surf forecast table for Aja provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Aja can be found by selecting the local surf guide option on the grey menu. Our Aja 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 (Aja) 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 Aja 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.
Aja is 4 km (2 miles) from the city of Tomigusuku. If you plan a holiday in Okinawa, look for hotels and other accommodation in Tomigusuku. Tomigusuku has rooms for a wide range of budgets as well as car hire and transport links.
