The Lowdown
Alright folks, Rusty here. Let's talk about what's on the table for this region. The next 16 days are a mixed bag, but don't get your hopes up too high.
Right now, we are looking at a pretty lean run. For the first couple of days, the surf is small and messy with a stormy vibe. There's a little window that pops up for Monday the 10th and Tuesday the 11th, but nothing that's going to get you calling in sick. After that, it goes pretty flat for a solid stretch. From Friday the 14th right through to the end of the forecast period, the wave energy just drops off a cliff. There are long gaps with no real surf to speak of, so you might want to find something else to do for a while.
Now, the only real standout in this whole period is Aja on Monday, August 10th. The swell ticks up to a clean 3ft to 4ft from the east, and the offshore wind is blowing light to moderate from the SE. That's going to give you some tidy little lines. The swell period is a very long 13 to 14 seconds, which means it’s a proper groundswell with some punch, but at a reef break like Aja, that long period actually works in your favour, shaping up nicely. The combined wave energy is solid, hitting around 413 to 437, so there's some proper grunt in the water for a reef break of this size. The water is sitting at 86°, which is a touch warmer than normal for this time of year, so you won't need the thickest suit.
Tuesday the 11th will still be rideable with the wind holding offshore, but the size drops back to 2ft to 3ft and the energy fades. It'll be a bit more ordinary.
After Tuesday, the wind stays offshore for most of the week, which is the one saving grace, but the swell just isn't there. From Thursday the 14th onwards, we're looking at waves under 2ft and a lot of days with zero energy. A few days in the second week like Saturday the 16th show a tiny blip of 2ft, but the energy is weak and the conditions are just poor. The end of the month looks completely flat with strong cross-off winds, which won't do anything for the surf but might make for some interesting kite action if you're into that.
Honestly, if you are desperate for a paddle, make the call for Monday the 10th at Aja. The rest of the window is a write-off. Keep an eye on it, forecasts can change, but right now it looks like a long, quiet spell.
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.
