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

Well, to be honest, it's a pretty grim start. We're looking at a long dry spell with no real surf on offer for the first week or so. From Friday the 10th right through to the end of the next week, it's just one big gap of nothing. The wind is howling, mostly gale force or stronger, and the swell is flat. It's just not happening.

The first glimmer of anything comes on Monday the 13th. We get a tiny pulse of swell, maybe 0.7ft to 1.0ft from the west and east, but it's so weak the energy is barely there (18 to 28). The wind is offshore and clean though, so it's a start. But honestly, you'd be hard-pressed to get a ride.

That tiny bit of swell sticks around through to Friday the 17th, but it's never more than about 3ft. The energy is still low (only getting to 106 on Friday afternoon). The wind stays clean, but the surf is just too small to get excited about. It’s a total tease.

Now, things get a bit more interesting as we head into the second week. Saturday the 18th sees a jump in size to 7ft, but with a nasty 25 mph cross-shore wind and a short, choppy 6-second period. That's a mess. Not one for the log.

The real standout, and this is the one to keep an eye on, is Aja (reef) on Tuesday the 21st of July in the morning. The swell is going to pump up to a solid 15ft from the east, with a decent 10-second period. The combined swell energy is a massive 3906, so there's plenty of power behind it. The wind is a cross-off at 19 mph, which should keep it reasonably clean. This is a proper groundswell, and for a reef, it'll be lined up. But listen – at 15ft, this is big, expert-only territory. It'll be a heavy, powerful wave, and definitely not for the faint of heart. It's also a reef break, so the long period will make it peg and barrel. Crowds could be possible here for a wave this good.

The rest of that week holds some size, with waves between 6ft and 12ft, but the wind starts to shift more cross-shore and onshore, lumping things up and making it a bit of a battle. By the weekend of the 25th, it drops right off again into the tiny stuff.

So, the standout is undoubtedly Tuesday the 21st. That morning session at Aja with a 15ft east swell and clean-ish wind is the one to circle. It’s a long way off, so the forecast could shift, but right now, it's the only real highlight in an otherwise quiet outlook.

Stay safe out there.

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.
