The Lowdown

Right, folks, Rusty here. I’m gonna level with you – for most of this forecast period, it’s a tough stretch here at Aja, a reef break that’s normally a bit fickle. The water’s sitting at 30°, which is about a degree warmer than usual for this time of year – nothing crazy, but it’s a touch balmy.

We’re looking at a real dry spell to kick things off. From Wednesday the 29th of July right through to the 5th of August, it’s a total bust. There’s just nothing doing – flat spells, poor conditions, and even when a tiny little 0.7ft ripple shows up on the Friday and Saturday, the wind’s not helping and it’s just not worth paddling out. The combined swell energy is basically zero (0), and the wave comments just scream “poor.” That’s a solid week of nothing.

You have to hold out hope for Thursday the 6th of August, but that’s a different kind of problem. We’ve got a massive E swell hitting 18ft to 20ft with a period of 19 seconds – that’s a very long-period groundswell with combined energy readings off the charts (24,069 – 26,078). The wind and tide might be favorable, but frankly, at this exposed reef break, that’s too big and powerful for anyone but the most elite hellman. The model even says the swell is predicted to be too big for this break. For the average surfer, that’s a big no-go.

The wildness continues on Friday the 7th of August morning with a 23ft NW swell (19,469 energy), but again, that’s serious business. By the afternoon, it drops to a more manageable 7ft but with a messy side-offshore wind. Still not the kind of day I’d rush for.

From Saturday the 8th onwards, we’re back into the doldrums. The clean-looking wind on some days doesn’t save us – the swell is tiny, often below 3ft, and the energy (83 – 198) is weak. Conditions are labelled as “marginal” or “very ordinary” right through to Thursday the 13th of August. You’ll see a few 3ft pulses from the E with some clean offshore winds on the 10th and 11th, but it’s small, and the quality just isn’t there for a good session. The magic just isn’t happening.

The real standout? Honestly, there isn’t one in the surf sense. If you’re an expert and live for massive, heavy groundswell, the Thursday 6th and Friday 7th are your window, but you better know what you’re doing. For everyone else, this is a long stretch of poor picks. The setup does look more interesting for kite surfing than paddle surfing on the bigger, choppier days.

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.
