The Lowdown

Alright, let me tell ya what’s shakin’. Honestly, for the next 16 days? It’s a tough stretch. There’s a big ol’ gap with nothing worth paddlin’ for, so don’t even bother waxin’ up just yet. We’re lookin’ at a real dry spell before things get a pulse. From Wednesday the 19th of August all the way through to Friday the 28th of August, it’s mostly blown out or flat. Gonna be a long wait, but hang tight—there’s a glimmer on the horizon.

The only real standout in this whole outlook comes right at the tail end of August. We’re lookin’ at Aja—a super exposed reef break that doesn’t fire all that often, so when it does, you take notice.

Come Saturday the 29th of August, the morning has some life. Swell bumps up to about 6ft out of the NNW, period around 10 seconds. The wind is light from the south at just 6 mph, nearly glassy. That’s cross-off, so the lines should be clean and the shape has potential. Combined swell energy is sitting at 776 (moderate)—enough to push through. The water temp is about 84°, pretty normal for this time of year.

Then Saturday afternoon gets even sweeter. The swell drops a touch to around 5ft, still NNW, but the period stretches to 11 seconds. That’s a touch of groundswell energy. And here’s the kicker: the wind goes glassy—3 mph from the SSE, dead flat. That’s as clean as it gets for Aja. Combined energy is 623 (moderate). For a spot that’s inconsistent and often needs the stars to align, this is your window. It might not be huge, but the quality will be there.

Best on offer: Saturday the 29th of August, afternoon. Light winds, clean lines, and a rare opportunity at a break that doesn’t always deliver. That’s the one to circle on the calendar.

Stay patient. 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.
