The Lowdown

Alright, folks. Rusty here. Let's see what we've got for the next couple of weeks.

Honestly, this is a tough one. There's a big gap of nothing at the start, and the whole period is mostly a struggle. The first decent swell we see is way out there, but it's a mess.

We're looking at Aja, a reef break. Water temp is about 29°, normal for this time of year.

From Sunday the 23rd through the end of August, it's a total write-off. The swell energy is flat, with readings like 0, 73, and 29 – barely a bump. Wind is cross-off or cross-on, and it's all tagged "poor surf conditions." A long, dry spell.

Into early September, things don't improve much. Tuesday the 1st sees a small 4ft swell from the NE with a short 5-second period, but it's cross-shore and lumpy. Not worth it.

Wednesday the 2nd builds a bit – 8ft to 8ft from the NNE (7 seconds), with moderate energy. But the wind is a fresh to strong cross-onshore, making it messy.

Then we get to the big one. Thursday the 3rd of September. We've got a massive pulse: 23ft on Thursday morning and 28ft on Thursday afternoon, from the E and ENE. The period is 14-15 seconds – very long period groundswell. The energy is insane, hitting 20658 and 30395. The notes say it's favorable for wind and tide, but the swell is predicted to be too big for this break. This is for experts only. With a near gale cross-onshore wind, it's going to be a dangerous, blown-out mess. For a reef, that long period can make it break too straight. This setup looks more interesting for kite surfing than paddle surfing.

After that, it drops off hard. Friday the 4th through Monday the 7th of September, it's back to poor surf with onshore winds from the NW. Swell sizes drop from 8ft down to 2ft, with moderate energy that quickly fades. All blown out.

So, the standout? There isn't one. The only real swell is that monster on the 3rd, but it's too big and too windy for normal surfing. The rest of the 16 days is a bust. I'd wait for a better forecast.

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.
