The Lowdown
Alright, grab your board and listen up. It’s Rusty, and I’ve gotta be straight with you – the next couple of weeks here are a real mixed bag. We’re looking at a long, frustrating stretch of flat or tiny, weak surf before a proper pulse of energy finally shows up. No sugar-coating it, the first half of this outlook is a waiting game.
Right now, and for the next week and a half, it’s pretty grim. The combined wave energy is pathetic, barely hitting 35 (35) at its best, and most days it’s a big fat zero. You’ll be chasing ankle-biters from the east at 1.0ft to 1.3ft with a mediocre 10-second period. The wind is mostly light and offshore or cross-off, which is a tease because the waves just aren’t there. It’s clean, but it’s clean for nothing. This is gonna be a solid 10-day gap with no real surf worth paddling out for.
We finally get a glimmer on Thursday, August 4th. That’s where the story changes. A solid groundswell from the east rolls in, pushing 7.2ft to 7.5ft with a period of 18-19 seconds. That’s a very long period swell, which means proper, generated energy. The combined energy rockets up to 3544 (3544) – that’s strong, serious power. The water temp is sitting at 82.8°F, which is a touch cooler than usual for this time of year, but it’s nothing to cry about.
Now, for Aja (Nusa Dua) – this is a reef break, and it’s exposed to the north swell window. This east-northeast swell is a good match. It’s a clean setup with a gentle offshore wind on Thursday afternoon, making for some beautiful, lined-up waves. Keep in mind, this swell is over 8.2ft. This is expert territory only. It’s too big for beginners and will be a handful for intermediates. The reef takes a lot of the energy and makes it more manageable than a beach break, and the long period will mean long lulls between sets, giving you time to get out the back. The crowds are “sometimes” an issue, but with this size, it’ll thin the herd.
Friday, August 5th, the swell is still pumping at 6.9ft to 7.5ft with a 17-second period, though the wind picks up to a moderate breeze. The offshore wind holds, so it’s still clean, but the energy is dropping slightly to 2566 (2566). It’s still a powerful day for experts. By Saturday and Sunday, August 6th and 7th, the swell starts to back down from 5.9ft to 3.3ft, the period drops, and the wind gets stronger and more cross-off, making it less appealing. The best bet is definitely that Thursday, August 4th session. It’s the standout. Get on it.

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.
