Table - best surf conditions forecast for Aja over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what Aja has in store for us over the next couple of weeks.
Straight off the bat, it’s looking pretty bleak. We’ve got a long, dry spell ahead, with no surf at all from Wednesday the 8th of July right through until late on Monday the 13th of July. That’s nearly a week of flat, windblown conditions. The wind is all over the place, mostly cross-off or cross, but without any swell to work with, you’re just staring at a flat ocean. Keep the boards in the car for now.
Things finally start to stir on Monday the 13th of July. The morning brings a tiny pulse of east swell, about 1 foot, but with only 9 seconds of period. That’s weak, low energy (15) and not worth paddling out for. The afternoon gets a little more interesting – a 3 foot east swell, but the period drops to a short-fetch 7 seconds. It’s surfable, but very ordinary, with the combined energy only reaching 76. The wind is offshore from the southeast though, which keeps the surface clean. But honestly, it’s marginal.
Tuesday the 14th is another dud, with the swell dropping back out. Wednesday and Thursday the 15th and 16th see the energy build again. But it’s not until Thursday the 16th of July that we get something to note. Thursday morning brings an 8 foot east swell with an 8-second period. Now, 8 feet is big, and with that short period, it’ll be a lumpy, powerful close-out at Aja. Only for the experts. The combined energy is a strong one at 1009. The wind is cross-off from the ENE, so the surface is clean, but the tide conditions look questionable, and it’s a marginal forecast. By the afternoon, the swell eases to 5 feet, but the wind swings cross-shore, adding a chop. That afternoon session is a pass.
The following days from Friday the 17th of July onward get messy. The wind turns onshore or cross-onshore, and the swell stays small and weak. Saturday the 18th has a 2 foot swell with a long 11-second period, but it’s cross-shore and choppy, not worth getting wet for. There’s a brief clean-up on Monday the 20th of July, with a small 2 foot east swell and a long 13-second period, giving it a bit of energy (82). The wind is gentle offshore from the ESE, so the conditions are glassy, but the waves are just too small for any real fun.
For the rest of the period, it’s a mix of clean offshore winds but tiny swell, or strong wind and poor quality. The standout window, if you can call it that, is really just the morning of Thursday the 16th for the big-wave crew. Other than that, this is a long, quiet stretch. The water temperature is about average for this time of year, but there’s just no power behind the waves.
Stay tuned, but don't hold your breath. This run looks like it’s going to stay poor for a while.
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.
