The Lowdown

Alright, Rusty here again. Gotta be straight with you—the next couple of weeks at Aja is looking pretty slim. We’ve got a real dry spell on our hands, so don’t be expecting any fireworks.

Right now, starting Wednesday the 12th of August, we’ve got tiny 2-foot easterly swell rolling in with an 11-second period, but the conditions are just ordinary. The water temp is sitting at a pretty normal 84°, so nothing unusual there for this time of year. The wave energy is weak, just 83, and we’ve got a light cross-off breeze. It’s surfable, but not worth getting excited about. That sets the tone for the next week and a half.

Thursday the 13th sees that swell drop a little, with a glassy window in the afternoon, 2 feet from the east, period dropping to 10 seconds. That glassy wind is a positive—makes for a clean surface—but the swell is too small to really get going. Saturday the 15th is similar, with glassy conditions again in the morning and afternoon, same tiny 2-foot east swell. It’s a pattern of “almost but not quite.”

By Sunday the 16th, we get a bit of a bump in the wind with a 12 mph offshore breeze in the afternoon, cleaning things up nicely for that 2-foot wave. But here’s the kicker—the swell is just too weak to be a real standout. The energy stays below 100 for basically the whole run.

We hit a real dead zone from the 18th of August all the way through to the 26th. There are several days with zero swell and poor conditions. Wind cranks up, and on the 24th we even see storm force cross-onshore winds of 62 mph—that’s straight-up dangerous, not surfable. Not worth paddling out.

Now, here’s a flicker of hope. Way out on Thursday the 27th of August, the model shows a change. Late in the afternoon, we get a glassy session with 3-foot easterly swell, an 11-second period, and a solid 244 combined energy. That’s moderate energy, finally. That’s the one to circle on your calendar. But it’s a long way off, so treat it as a promising maybe, not a sure thing.

So as it stands, there’s no true standout in this forecast. It’s a long, flat stretch with only a whisper of hope at the very end. Hang tight, check back closer to the 27th.

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.
