The Lowdown
Alright, listen up. Let's cut through the crap and talk surf.
For the next few days, it's just not happening. There's a poor, weak swell and a moderate breeze making everything flat and bumpy. Tuesday morning might give you a waist-high ripple, but it's not worth your time. We're looking at a real dead period from Wednesday all the way through next week. The swell just disappears, and it's going to be a struggle to find anything rideable. The good news is the wind is mostly light and clean, but with no swell, that's like having a Ferrari with no gas.
There is a pulse of junky, short-period swell arriving on Thursday the 20th and Friday the 21st. It pushes to 8ft (2.4m) and 8ft (2.5m) but the energy is all over the place (737 and 695 combined energy). It's going to be a stormy, messy mess with onshore winds, making it less of a surf day and more of a blown-out bump fest. A beach break would be a kite-surfing dream, but not for a paddle surfer.
Now, here's the light at the end of the tunnel. Mark your calendar for September 1st, which is a Tuesday. The long-range models are showing a proper groundswell. By Tuesday afternoon, we're looking at a solid 14-15ft (4.5m) of SW swell with a long 12-second period. The energy reading is a massive 8277, and with offshore winds, Junkyards (Big Island) is going to be absolutely firing. This is the standout. This is the one. It's a reef, and that long period will make for some grinding, hollow waves. This is for the experts, and it's going to be special.
But here's the catch. The day after, on September 2nd, the swell just goes nuclear. We're talking about a monstrous 24-28ft (7.5m-8.5m) of WNW swell with a period of 12-13 seconds. The energy numbers are off the charts (15,498 and 24,371). It's just going to be too big for Junkyards. That's a life-or-death, big-wave-only event. The whole coast will be a washing machine. Only the most insane chargers will even think about it.
So, the takeaway is this: the next week is a write-off. Save your energy, check your gear, and get ready for that Tuesday the 1st. That's the window. That's the dream. After that, it's on to the next level of madness.

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.
