The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.

Right off the bat, I gotta be straight with you – it’s looking pretty bleak for a solid stretch. The first real sniff of anything surfable doesn’t come until Thursday, 23 July. That’s a full five-day gap with nothing worth paddling out for. We’ve got a long run of tiny, weak swell and messy wind, so don’t bother checking the lineup until then.

Now, Aja is a reef break, and it’s exposed to the north swell window. For the first week, the swell is tiny, mostly 2ft to 2ft from the west or east, with periods all over the shop. The combined energy is weak, rarely cracking 50 (51 is the highest early on). The wind is mostly cross or cross-off, but the waves just aren’t there. The water’s sitting at 81°, which is a solid 4° colder than normal for this time of year – that’s a notable chill, so you’ll want a thick wetsuit.

The one bright spot in the first week is Thursday morning, 23 July. We get a tiny 2ft swell from the east with a 10-second period, but the real story is the wind. It’s glassy – absolutely dead calm. The combined energy is only 52, and the commentary says “surfable waves but very ordinary conditions.” It’s not going to blow your mind, but it’s the only time in the first week you might get a clean little wave. This break is inconsistent, so don’t bank on it.

After that, it’s back to tiny, weak junk until the end of July. The period from 24 July to 28 July is all 1.0ft to 2ft, short-period windswell, with building onshore winds that go from fresh to strong. By Tuesday, 28 July afternoon, we’ve got a 3ft northwest swell but with a 34 mph near-gale blowing straight onshore. It’s a mess.

Now, hold on to your board. The stand-out, and I mean the only real standout in the whole 16-day window, is Wednesday, 29 July. A big 8ft east swell rolls in with a very long 16-second period. The combined energy is a massive 2783 – that’s strong, powerful groundswell. But here’s the catch: the wind is a 43 mph gale from the west-northwest, cross-onshore, with moderate rain. The commentary says “gale force cross-onshore and completely blown out.” This is strictly for experts only, and honestly, the wind is going to ruin it. With that kind of period and size, it’ll be breaking straight at a beach setup, but since Aja is a reef, it might hold some shape if the wind ever let up. It doesn’t. This is a kite-surfing day, not a paddle day.

Thursday, 30 July, still has a decent 5ft east-northeast swell with a 14-second period (energy 958), but the wind is still a strong 31 mph near gale, cross-shore, making it lumpy and tough. The swell drops quickly after that, and by the first week of August, we’re back to weak, small 0.7ft to 3ft swells with moderate cross-shore winds.

So, to be honest, there’s no real gem here. The best window is the morning of 23 July for a tiny, clean, glassy wave if you’re desperate. The big swell on the 29th is a beast, but it’s blown to hell. This is a region where a blank run like this happens – sometimes the ocean just doesn’t deliver. Forecasts can change, but right now, it’s a wait-and-see situation.

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.
