The Lowdown
Alright folks, Rusty here. We've got a rough stretch ahead for Joss Bay. Looking at the whole 16-day run, there's just nothing doing for a surfer.
The pattern is a big, flat, windy mess. Right from the start on Friday, August 28th, it's tiny with a 1.0ft swell from the NE. The period is short at 6 seconds, the combined energy is weak (5), and a moderate offshore wind is blowing. But the forecast says it's poor surf, so don't bother paddling out.
Saturday the 29th through Monday the 31st is a write-off. We're looking at waves barely reaching 0.3ft to 0.7ft. The winds are mostly fresh and strong, sometimes offshore but often cross-off, making it a total battle with nothing to ride. There's very weak wave energy (1-3) and short periods.
From Tuesday, September 1st all the way through to Monday, September 7th, it's practically a drought. Swell heights hover around 0.3ft with periods of 6-10 seconds. The energy is rock bottom (1-2). There's a brief moment on the morning of September 7th with glassy conditions, but on a 0.3ft wave, that's just a flat, pretty pond.
A glimmer appears on Wednesday, September 9th. The swell bumps up to 5ft from the NNW. It's short-period windswell at 5 seconds, but the energy finally kicks up to moderate (80-84). The morning looks clean with a moderate cross-off breeze. The afternoon on the 9th and the morning of the 10th are described as "surfable waves but very ordinary conditions." That's it. For a window. It's not great, but it's the only rideable surf we get. For a beginner, 5ft might be a bit punchy on a short period wave, but an intermediate could find something.
After that, Friday the 11th and Saturday the 12th of September get blown out by near-gale force winds. Big winds, tiny 2ft to 0.3ft waves—not worth it.
So, there you have it. A solid week and a half of near-zero surf, with two mornings of ordinary waves right on the 9th and 10th of September. If you're hanging on for something, those two mornings are the only real chance. Otherwise, it's a stretch to forget.

Information about the Joss Bay Surf forecast
The above surf forecast table for Joss Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Joss Bay can be found by selecting the local surf guide option on the grey menu. Our Joss Bay 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 (Joss Bay) 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 Joss Bay 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.
