The Lowdown
Alright, let's get into it. It's Rusty here, and I'm looking at the cards for Joss Bay, and I gotta tell you, it's a tough stretch ahead. We're looking at a solid 16-day window, but the real story is that there's almost no surf to get excited about. This is one of those long, flat runs that can just kill you.
For the first week, it's basically a write-off. We're talking about tiny, weak swell and poor conditions. From Monday the 10th right through to the end of the week, the surf is just too small and ragged. The water temperature at Joss Bay, at 69°, is feeling much warmer than normal for this time of year—that's a 7° anomaly, so it's pretty unusual. But you'll be sitting on your board doing nothing. The wave energy is minimal, hitting a low of just (2) at times. The wind is mostly onshore or cross-onshore, mushing up the lil' bumps of 1ft to 3ft of swell that do show up. It's basically a lake out there for paddle surfing. If you've got a kite, those breezes from the 11th onwards might look half-interesting, but for a surfer, it's a no-go.
We hit a real quiet patch in the middle of the month. There's a brief flash of hope on Saturday the 15th with glassy conditions in the afternoon, but the swell is a pathetic 0.3ft from the north. You'd need a wave pool. That nothingness carries right through until the 22nd.
Now, towards the very end of the forecast, things start to look a little less grim. Saturday the 22nd of August shows some promise. The morning has a gentle offshore breeze from the SW, and the swell is 2ft from the NNE. It's still tiny, but the energy is up a bit at (48), and it's clean. The afternoon looks okay too, with a cross-offshore wind. It's not a standout by any stretch, but it's the best of the bunch.
Then we get to Sunday the 23rd and Monday the 24th. The swell bumps up to 4ft from the east, with cross-offshore winds and glassy conditions. The wave energy gets into the moderate range, hitting (77) on Monday morning. The period is short, around 5-6 seconds, so it won't have any real grunt, but at least there's something to push around. Joss Bay is an inconsistent wave, and it's often crowded, but with this kind of run, that might not be an issue.
Honestly, the only time I'd even bother paddling out in this 16-day window is that Saturday the 22nd through Monday the 24th. The surf is small, but it'll be clean with those offshores. If you're a beginner, the 4ft swell is about your limit. It's not going to be epic, but it's something. For the rest of it? Leave the boards at home.
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.
