The Lowdown
Right, folks, Rusty here. We’re looking at a pretty grim stretch for Aja over the next 16 days. The pattern is a whole lot of nothing, with a few glimmers of hope that are still just “ordinary” at best. The first week is a total write-off, and it’s not until the second week that we might see a couple of okay sessions.
The water's sitting at 86°F which is a touch warmer than normal for this time of year, so if you're paddling out, you won't need a thick suit.
Let's be honest, the first week is a bust. For the first four days, from Friday 7th through to Monday 10th, we've got a big, powerful swell brewing, but it's completely unsurfable. The light here is red. On Friday 7th, we’re looking at a huge 10ft swell from the east with a 15-second period and a massive 8438 combined energy, but it’s being hammered by a 43 mph westerly gale. That’s just a washing machine. By Saturday 8th, it drops to a tiny 2ft, but the wind is a severe gale. That theme continues all the way through to Wednesday 12th – the swell is tiny, below 3ft, and the wind is too strong to make anything of it. There’s a solid 5-day gap here with absolutely no recommendations.
The first sign of life comes on Wednesday 12th afternoon. The swell is a pathetic 2ft from the east with an 11-second period and a weak 59 combined energy. The wind is a light breeze, so it’s clean, but the comment is “surfable waves but very ordinary conditions.” That’s the best of the first week, and it’s not good.
The second week is a little more interesting, but still nothing to write home about. From Saturday 15th through to Sunday 16th, we get a run of clean conditions with a 2ft east swell and a 12-second period. The energy is low, around 130-141, but the wind is light and cross-offshore. These are the standout windows, but only because everything else is so bad. The waves will be small and weak, but at least they’ll be clean.
The only notable rise in size comes on Thursday 20th August. The swell jumps to 8ft from the east with a 9-second period, and combined energy hits 1162. The wind is a clean 16 mph cross-offshore, so it’s not blown out. The comment says “marginal surf forecast or questionable tide conditions.” That’s a big swell, over 8ft, so it’s expert territory only, and the short 9-second period means it’ll be a bit crumbly and less powerful. It’s a big, messy, heavy wave for the brave.
After that, it drops right off again. Friday 21st is flat, and Saturday 22nd brings back a tiny 3ft to 4ft east swell with a short 7-second period.
The best of the lot is the Thursday 20th if you’re an expert, or the clean but tiny conditions on Saturday 15th and Sunday 16th for a beginner on a longboard. Honestly, don’t get your hopes up.
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.
