The Lowdown
Alright folks, this is Rusty. Let's get into it.
Right off the bat, I gotta be straight with you. The outlook for Aja is a tough one for the next two weeks. We’re looking at a long stretch of flat, weak, or just plain messy conditions. Don't get your hopes up for any real action.
The first few days are a write-off. Tuesday the 21st and Wednesday the 22nd are seeing tiny 1ft swell from the east with next to no energy. The wind is all over the place, but the swell is just too small to do anything with. It’s a classic case of poor surf conditions.
We get a tiny glimmer of hope on Thursday the 23rd afternoon. The swell bumps up to a meagre 2ft from the east, and the wind goes glassy. For a moment, you could have a couple of little knee-high rollers. But we’re talking about weak wave energy and the conditions are described as "surfable waves but very ordinary conditions." It’s not enough to get excited about.
From Friday the 24th through to the end of July, the swell drops back to 1.0ft to 1ft, and while the wind is often clean, the swell is either too small or non-existent. The water temperature here is 82°, which is a bit colder than normal for this time of year, but that's the least of your worries.
The real kicker comes near the end of the month. On Thursday the 30th of July, we see a pulse of 3ft windswell from the WNW, but it’s got a short period of 8 seconds and the wind is a messy cross-shore. The combined energy of all swells directed here jumps to 130, which is moderate, but the conditions are still flagged as "poor surf conditions." With the wind being cross and the swell being short-period windswell, this is all chop and no shape. Honestly, this setup looks more interesting for kite surfing than paddle surfing.
The whole first week of August is a bust. We see a few instances of a very long period swell (16-19 seconds) from the east, but the swell height is tiny at 0.7ft to 2ft. For a reef break, that long period on a tiny swell just means a long wait for a wave that barely stands up. The energy is moderate at best, and the wind is either onshore or cross-onshore, ruining any chance of a clean wave.
The last few days of the outlook show a slight increase in energy, with combined energy of all swells directed here hitting 177-206, but the swell is still only 2ft from the east, and the wind is a moderate cross-onshore chop. Again, it looks messy.
There is no standout day. No hidden gem. This is a blank run for the area. It tends not to stay poor for long, and forecasts can change, but as it stands, there’s nothing to recommend. Save your energy for another day.
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.
