The Lowdown

Alright, grab a coffee, let's have a look at what's on offer for Aja over the next couple of weeks. Straight up, it's a tough stretch. We're looking at a long gap with nothing worth paddling out for, so don't be in a rush.

We kick off on Sunday, September 13th, with a tiny 1ft east-northeast swell on a 14-second period, but it's crossed off at 12 mph. The combined energy is weak at 68, and it's just poor surf. That theme sticks around for days. Monday the 14th and Tuesday the 15th offer a tiny 1ft swell, but the conditions are described as "surfable but very ordinary." There's a light breeze, but with such minimal energy (56), it's barely a ripple.

We get a slight bump on Wednesday the 16th morning, with the combined energy climbing to 91, but it's still only 1ft. By Thursday the 17th morning, the energy hits 114, and the swell lifts to 2ft from the east at a 14-second period with a cross-offshore ENE breeze at 9 mph. It's clean, but still very small and ordinary. It’s really not worth getting excited about.

Then the wind kicks up. Friday the 18th and Saturday the 19th bring stronger cross-shore breezes and chop. On Saturday morning, a 4ft east swell with a 16-second period rolls in. The combined energy is a massive 768 (moderate), but it’s crossed by a 16 mph NNE wind. The forecast calls it "marginal surf," and with that wind, it's a messy proposition. This is a groundswell with a long period, so it'd have more shape if the wind was right, but it's not. It's too rough for beginners at that size, but it's still not clean.

Sunday the 20th is a write-off. We see a 8ft east swell at a 14-second period, but with a 28 mph north cross-onshore wind, it's blown out. The energy is a massive 2427 (strong), but you'd be mad to go out. That's strictly for experts, and only if they have a death wish. Monday the 21st has a 4ft swell and offshore wind, but it’s still labelled as "poor surf." The rest of the week and into the following week is just a series of lumpy, choppy, cross-onshore days. The swell hangs around, often around 3ft to 5ft, but the wind is relentless from the north and northwest, gusting up to 19-28 mph, making for messy, blown-out conditions.

There is a spike on Monday, September 28th, afternoon, with a 5ft east swell on a 12-second period and combined energy of 744 (moderate), but it's crossed-on by a 16 mph north wind. It's described as "moderate cross-onshore and choppy," so still not good.

To be honest, for the entire 16-day window, there's not a single standout session. The best bet might be a dawn patrol on Thursday the 17th or Wednesday the 16th if you're desperate, but you'd be surfing ankle-biters. The setup here, with the wind and size, looks more interesting for kite surfing than paddle surfing. Keep an eye on the charts; it tends not to stay this poor for long.

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.
