The Lowdown
Alright, folks, it’s been a quiet stretch here at Junkyards (reef). For the first week and a half of this outlook, we’re looking at a whole lot of nothing. There’s a long gap of poor surf and tiny windswell, so if you’re desperate for a paddle, you’re better off waiting. The water temp is sitting around 84°, which is about normal for this time of year, so at least it’s warm.
Things finally wake up around Saturday the 26th of September. That morning we see a small pulse of 2 ft swell coming from the SE with a period of 10 seconds, but the wind is light onshore from the W, making it choppy. The combined energy is still weak at 50, so not much to get excited about. By the afternoon, the swell picks up a bit to 2 ft, and the period jumps to a very long 16 seconds – classic groundswell potential. The energy climbs to moderate (220), but the wind shifts cross-onshore from the WNW, so it’s going to be a bit bumpy. Still, that long period means the shape could be there for a reef set-up like this, so if you’re an experienced surfer, it might be worth a look for a few clean ones between the chop.
Now, the real news – and I mean the standout of the entire 16-day window – hits on Monday the 28th of September. We’re talking a serious shot of swell. That morning, the Junkyards are forecast to see a solid 13 ft swell from the SE, with a very long period of 16 seconds. The combined energy is powerful (7411), and the wind is light offshore from the N, making a clean, cross-off breeze. This is big, powerful stuff. At 13 ft, this is strictly for experts. Beginners, stay on the beach. The wave quality could be exceptional, but the sheer size and power will demand respect. The afternoon pushes it even bigger to 15 ft, still with clean cross-off winds, though the energy is slightly higher (8630). This is the day to watch.
Tuesday the 29th of September keeps the run going, with a massive 16 ft swell from the SE, period at 15 seconds, and a combined energy of 12345 – that’s strong. The wind stays offshore from the NNE, but there is a risk of thunderstorms. Again, this is only for the most experienced chargers. By that afternoon, the swell drops back to zero, so the window is tight.
Wednesday the 30th is one for the history books if it verifies – but it’s a long way off. The morning shows a monster 21 ft swell from the SE, period of 14 seconds, and the combined energy is massive at 15726. The wind is cross-off from the NE, but the data suggests the swell might simply be too big for this break, even for experts. It’s a long-range forecast, so take it with a grain of salt, but the potential is there.
So, here’s the takeaway: The first week-plus is dead. The standout window is Monday the 28th through Tuesday the 29th, with big, powerful, clean groundswell for experts only. The 30th could be even bigger, but that’s a wait-and-see.
Stay safe out there.

Information about the Junkyards Surf forecast
The above surf forecast table for Junkyards provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Junkyards can be found by selecting the local surf guide option on the grey menu. Our Junkyards 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 (Junkyards) 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 Junkyards 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.
Junkyards is 5 km (3 miles) from Misato. If you plan a holiday in Okinawa, look for hotels and other accommodation in Misato. Misato has rooms for a wide range of budgets as well as car hire and transport links.
