Alright, listen up. It’s a slow start at Aja, a reef break that’s *inconsistent*, and we’re looking at nine days of pretty much nothing from now through the morning of Wednesday, 16 July. The water’s at 83°F, which is normal for the season – nothing to write home about.
The first real chance to get wet is the morning of Wednesday, 16 July. We’ve got a 6ft east swell with a 10-second period, and the combined energy is a solid 785 – that’s moderate to strong power. The wind is a gentle offshore from the ESE, so it’ll be glassy. For Aja, the east swell is right on the money for its optimum direction, so this is the best of the bunch. At 6ft, it’s a bit much for beginners, and since it’s an *inconsistent* break, the sets will be spaced out. Crowds are possible, so keep an eye out.
After that, things get a bit messy. On the morning of Friday, 17 July, there’s a 5ft northwest swell, but the period is a short 7 seconds, so it’s weak and crumbly, with a combined energy of only 293. The wind is cross-offshore, so it’s rideable, but nothing special.
The next decent window is the morning of Wednesday, 22 July. We’ve got a 6ft east swell with a 9-second period and a combined energy of 459. The wind is a moderate offshore from the SSE, so it’ll be clean. Again, it’s a reef break and it’s *inconsistent*, so the sets will be spaced out, but when they come, they’ll be good. The swell direction is on the money, so this is your second-best bet.
So, to sum it up: you’ve got two real windows in a 16-day forecast. The morning of the 16th is your best bet for size and power, and the morning of the 22nd is the next clean shot. The rest is a long, flat wait.

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.
