Table - best surf conditions forecast for Aja over the next 16 days.
Alright, folks, Rusty here. Let’s have a look at what’s in store for the Aja stretch over the next couple of weeks.
Straight up, it’s a tough one for the next week or so. The surf is small and messy, and the wind is a real problem. We’ve got a long stretch of poor surf conditions from Thursday, July 9th right through to the end of the following week. There’s a gap of about 10 days with no real reason to get wet. The wind is howling from the east and southeast, mostly cross-off or cross-off, but with near gale to gale force gusts on the 11th – that’s going to be a battle just to get out. The water temp is sitting around 84°, which is pretty much normal for the time of year, so no wetsuit worries there.
The first faint glimmer of hope comes on Friday afternoon, July 17th. We finally see a pulse of swell, about 3ft from the ENE with a period of 9 seconds. The energy is still weak, just 113, but it’s something. The wind is a gentle offshore from the ESE, which will clean it up. It’s a reef break, exposed to the north, so it’s not a consistent spot, and it’s known to be inconsistent. It’s still just ‘surfable waves but very ordinary conditions’, so keep your expectations in check. Crowds are possible, but with this showing, it’s unlikely to be packed.
The next real chance doesn’t show up until a week later. Tuesday, July 21st, the swell picks up to 5ft from the east, period 7 seconds, with energy climbing to 181. That’s a moderate amount of juice. The wind is a fresh breeze from the ESE, cross-off, so it’ll be clean. Wednesday, July 22nd, looks slightly better: 5ft from the east, period 8 seconds, and energy at 236. Still a cross-off wind from the ENE. This is not for beginners – over 5ft is pushing it – but for experienced surfers, this is the best of a flat run. The swell direction is northeast, which is the optimum for this break, so it should wrap in nicely.
Later in the week, things settle down but stay small. Friday, July 24th, we get 3ft from the east, period 8 seconds, with a light cross-off breeze from the east. It’s clean, but the energy is down to 99. It’s surfable, but nothing to write home about.
So, the standout is the window around July 21st to 22nd. That’s your best bet for a real wave. The swell is the biggest, the wind is offshore, and the direction is on the money. It’s a reef break, so the longer period (8 seconds) is fine, but it’s not the super long-period groundswell that needs a point break. Still, it’s the one to target. The rest of the forecast is a waiting game, but it’s an inconsistent spot, so a blank run like this is pretty normal.
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.
