The Lowdown

Alright, I’ll take a look at what’s going on for Aja over the next couple of weeks. For this break, it's a bit of a slow start, but there are a couple of windows that might get the heart beating.

Right off the bat, the first few days are pretty flat and messy. From Saturday the 29th of August through to Monday the 31st, we’ve got tiny swell – just 1 ft to 2 ft – and the wind is howling. It’s not worth paddling out. That said, the water temp is about average for this time of year, so if you’re just floating around, it’s fine. But for surfing? Forget it.

Then into Tuesday the 1st of September, things shift. Tuesday afternoon, the swell jumps up to 8 ft from the east with a 9-second period. That’s a big step up, and the combined energy hits 1001 (strong). But here’s the thing – that’s a lot of juice for an exposed reef break like Aja. For experienced surfers only. The wind is offshore from the SSE at 16 mph, which should keep things clean, but an 8 ft east swell with that period can be a handful and a half. Only worth looking at if you’ve got the skill and the nerve.

Wednesday the 2nd is a step down – 3 ft in the morning and 6 ft in the afternoon. The afternoon has clean conditions (cross-off wind), but the score is low. The combined energy is 666 (moderate), but the swell direction is east, which is what Aja wants (optimum from the north, but east is exposed). Honestly, the Tuesday afternoon is the only real standout in the first week.

The second week is pretty messy. There’s a gap from Thursday the 3rd all the way to the following Tuesday the 8th with no real recommendations. Winds swing around onshore and strong, and the swell drops off to nothing or gets chopped up. By Saturday the 5th, there’s a tiny 1 ft WNW windswell – that’s practically no surf.

There’s a glimmer on Sunday the 6th of September – morning sees 6 ft from the east, 8-second period, with a combined energy of 364 (moderate) and light ENE winds at 9 mph, cross-off. That’s clean and rideable, but the period is short (8 seconds) so it’s going to be a bit weak and slopey. Not a standout, but if you’re desperate, it’s the best of a bad run.

Further out, on Friday the 11th and Saturday the 12th of September, we get a long-period east swell – 13 seconds – with swell around 4 ft to 5 ft. The combined energy sits around 578 to 672 (moderate). For a reef like Aja, that long period (groundswell) could mean proper, lined-up waves, but the winds are cross or cross-off, and it’s still a risk for thunderstorms. That Saturday the 12th morning with gentle cross-off breeze and clean waves is the most promising of the whole 16-day window. It’s not huge, but the quality should be there.

Alright, overall, the best bet for a decent session is Tuesday the 1st of September afternoon if you’re an expert, or Saturday the 12th of September for a cleaner, more manageable swell. Don’t expect much in between.

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.
