The Lowdown
Alright, Rusty here. Let's be straight with you—this is a tough one for Joss Bay. The next 16 days are looking pretty grim. I've scanned through every single forecast, and there's just no good surf to be found. The whole window is a write-off, so don't bother checking the cam every five minutes.
The problem is a lack of any real swell. The energy is flat, with readings barely reaching double digits—most of the time it's below 20 (weak energy). The wave heights are tiny, usually between 0.3ft and 1ft, and when there's a little bump, the period is short, under 8 seconds, which means weak, crumbly waves. Plus, the wind is a mess. It's either howling onshore, making it choppy, or blowing so hard offshore that you'd be fighting a gale just to get out. There's no happy medium.
For a brief moment on Monday the 10th of August, there's a 3ft swell from the north, but it's accompanied by a 4-second period and a moderate cross-shore wind. The energy is only 21 (weak). It's still poor. Then on the 19th of August, we see a similar 3ft push from the north-northwest, but again, it's a short-period 4-second swell with a cross-offshore breeze. The energy is 22 (weak). It's just not enough to make it worthwhile.
The rest of the days are dominated by tiny, anemic waves and poor conditions. Even when we get a glassy morning on the 9th of August, the swell is only 0.3ft. There's absolutely nothing to get excited about. It's a proper blank run for Joss Bay.
So, my advice? Don't paddle out. Save your energy. Look at the lake, go for a run, or tune up your board. This stretch is a total dud. The forecasts can change, but right now, it's a solid "no" from me.
Rusty.

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.
