The Lowdown
Alright, Rusty here. Let’s have a look at Aja.
Right now, there’s not a single wave to surf. The whole first week is a total write-off. We’re looking at a long dry spell from Friday the 24th of July all the way through Friday the 7th of August. That’s a solid two weeks with nothing worth paddling out for. The swell just isn’t there, and even when a tiny bump shows up late in July, it’s puny, short-period, and won’t wrap in properly. The water temp is sitting at 84.2°, which is about normal for this time of year, so at least the water’s warm when you’re floating around waiting for nothing.
The only real light at the end of the tunnel shows up on Saturday the 8th of August. We finally get a pulse of solid swell – 9.8ft from the east, with a long period of 17 to 18 seconds. That’s a proper groundswell, with a lot of energy behind it (combined energy of 5795 to 6103). But listen, that’s huge. Over 8ft, so this is strictly for experienced surfers only. Aja is a reef break, so with that long period, the waves will be lining up nicely, but with east-northeast winds blowing cross-offshore, it’ll stay clean. The size and power will make it pretty intimidating for anyone but the experts. The wind is moderate, not glassy, but it’s workable. The crowds at Aja can show up sometimes, so expect a few others in the water if you’re game.
If you’re a beginner, don’t even think about it. This is a big-wave day for the crew. And honestly, with that much east swell and a stiff cross-offshore wind, the setup might actually be more interesting for kite surfing than regular paddle surfing. But for the hardcore, that Saturday the 8th of August is the only standout in this whole 16-day window. The rest of the outlook 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.
