The Lowdown

Alright, Rusty here. Let's have a look at what's on the table for this stretch.

Well, I gotta be straight with you—this is a tough one. For the next few days, Aja is getting hammered by strong winds and a whole lot of nothing. Thursday the 20th through Sunday the 23rd are basically a write-off, with zero to tiny swell and stormy winds. You’re looking at a solid four-day gap before anything even thinks about showing up.

Then, Monday the 24th of August, things start to get interesting. We’ve got a big pulse of energy arriving. The swell is coming from the east at 7ft, with a very long period of 18 seconds. That’s proper groundswell. The combined energy is a massive 2686, which is strong. The wind is a cross-offshore breeze from the ESE at 19 mph, which will keep the surface clean. The water temperature is 84°, which is bang on average for this time of year. This is a reef break, and that long-period east swell will wrap in nicely. Monday afternoon looks even better, with the swell pushing up to 8ft and the energy jumping to 4528. That’s serious power. This is the standout window. It’s a bit on the big side for beginners, but for the experienced crew, this is going to be firing. The only downside is that with a reef break and a long-period swell, it can get a bit wally and a bit intense, but for the right surfer, it’s pure gold.

Tuesday the 25th keeps the goods coming. The swell is still big, around 8ft to 10ft from the east, with a period of 16 to 14 seconds. The energy is still very strong, well over 3000. Winds are lighter from the ENE, and it’s clean. Again, this is for the experienced surfer only. The crowd situation at Aja is "sometimes," so you might have company, but it’s not a zoo.

By Wednesday the 26th, the swell starts to drop back to 5ft, but the wind goes onshore from the NW. That’s a dealbreaker. It's going to be messy.

After that, from the 27th of August all the way through the 3rd of September, we’re back to small, choppy, and generally poor conditions. There’s a little bump on the 2nd of September with 4ft from the east, but it’s cross-shore wind and short period, so it’s not going to be any good. A four-day gap, then a couple of days of magic, then a long stretch of nothing.

So, to put it simply: If you’ve got a board and the skills, you’re looking at Monday the 24th and Tuesday the 25th of August. That’s your window. Don’t be late.

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.
