The Lowdown
Alright, Rusty here again. Let me give it to you in feet and miles. Aja is looking pretty grim over these next 16 days. This reef doesn't break often, and this stretch is living up to that – there's a big gap from now (around July 16) all the way to July 23 with zero surf worth mentioning. Tiny waves, cross winds, poor conditions – just forget it.
Then on July 24, Friday morning, we finally get a little bump. Swell is only 2ft from the east, period 10 seconds, and with a light cross-off breeze from the ENE at 3 mph, it'll be glassy. Combined energy is a weak 80. It's surfable but barely – a longboard morning if you're really keen. Not the direction Aja likes (north is best), so don't expect much.
Then another dead stretch until July 30, Thursday morning, when a bigger pulse arrives: 6ft swell from the west, period 12 seconds – a nice long-period groundswell. Combined energy hits 872 (moderate). Wind is light from the NNE at 3 mph, nearly calm, so clean conditions. But the swell is from the west, not the north that Aja favours. And at 6ft, that's over the beginner limit – only for intermediates or better. The forecast also says "marginal surf or questionable tide conditions." So it's the best of a bad lot, but still iffy. For an inconsistent spot like this, it might be worth a look if you're experienced, but don't get your hopes up.
After that, it fizzles out again. A classic Aja dry spell – sometimes that's just how it goes. Forecasts can change, but right now I'd wait for another window.
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.
