The Lowdown

Alright mate, here’s the honest truth: the next 16 days at Aja ain’t bringing much to get excited about. There’s a long dry patch, and only a couple of brief windows where you’d even want to get wet. Most of it’s either flat or blown out, with a big gap of poor surf from the 12th through the 17th, and another dead spell from the 20th to the 24th. Not a great outlook.

Right now, Tuesday the 11th is the brightest spot, and that’s not saying much. Aja’s got a small 3ft wave from the east with a long 12-second period – that’s groundswell, with moderate energy (181). The wind is light and offshore from the southeast in the morning, so it’ll be glassy and clean. Water temp is 85°, about average for this time of year, nothing wild. Aja’s an inconsistent reef that really needs a north swell to pump, and we’ve got east swell, so it’s not ideal. But with that offshore wind, you might pick off a few long, lined-up waves. It’s small enough for beginners, and crowds can show up sometimes, so don’t expect solitude.

By Tuesday afternoon, the wind swings south and stays cross-offshore, still clean, but the swell drops to 2ft. Still rideable, just.

After that, Wednesday the 12th starts with a risk of thunderstorms and a southwest wind. Swell drops to 2ft with an 11-second period, and energy drops to 86 (weak). By afternoon, the wind goes north-northeast and cross-shore, messing up the surface. Not worth it.

From Thursday the 13th to Monday the 18th, it’s mostly onshore or cross-onshore wind, with swell staying below 3ft. There’s a little bump on Tuesday the 18th morning with 4ft from the east, but it’s only a 6-second period – windswell, short and weak, with moderate energy (163). The wind is cross-offshore and clean, so you might find something, but it’s not good.

Then it goes flat from the 20th to the 24th. Almost no swell at all, even though the wind is offshore. Nothing to ride.

Right at the end, on Monday the 25th and Tuesday the 26th, we get a big spike. On the 25th morning, it’s 5ft from the east with an 8-second period, and by afternoon it jumps to 6ft from the east-northeast. Energy jumps to 326 (strong) and 456 (very strong). Wind is strong cross-offshore, so it’s clean but powerful. On Wednesday the 26th morning, it gets messy with strong south winds and 7ft from the north-northeast, but by Wednesday afternoon we see a huge 12ft east swell with a 14-second period. Energy is massive at 5543 (very strong). That’s expert-only – over 8ft, and with that long period, it’ll be a powerful groundswell. Aja’s a reef, so it could handle it, but the wind is cross-offshore and conditions are listed as marginal, so it’s a gamble. That’s the only real standout in the whole 16 days, but it’s way out on August 26th – keep an eye on it, but don’t hold your breath.

So, if you’re keen, early Tuesday the 11th is your best bet. After that, it’s a waiting game. This stretch looks more like a time to find a different hobby.

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.
