The Lowdown
Alright folks, Rusty here. Let's take a long, hard look at what's on the table for Joss Bay over the next couple of weeks. I gotta be straight with you from the get-go, it's looking pretty bleak out there for paddle surfing. We’ve got a massive stretch with next to nothing worthwhile.
The first bit of the outlook is a rough one. From now right through until the 19th of September, you’re looking at a solid 12-day stretch of practically zero surf. We're talking tiny, barely-there ripples, mostly under 0.3m, with very weak combined swell energy, often reading just 1 or 2 (weak energy). The period is short, usually around 6 to 8 seconds, so no power behind it. You might catch a glassy-looking morning on the 9th with a 1-foot NE windswell and almost no wind, but it’s labelled as poor surf conditions for a reason – there’s just no wave to ride.
The only real glimmer in this whole forecast pops up on the morning of Sunday, the 20th of September. Now, we finally see a pulse of energy. The swell jumps to 5 feet from the NNE, with a period of 6 seconds, and the combined energy hits 171 (moderate wave energy). It’s still a short-period swell, so it’ll be a bit bumpy and lack that long, drawn-out wall, but it’s the biggest size we’ve seen in a fortnight. The wind will be a gentle offshore from the SW, keeping the faces reasonably clean. For a brief moment, there’s a chance for a few chunky, dumpy lefts. This is the one to circle on the calendar if you’re desperate for a paddle, but don’t get your hopes up for anything classic.
After that brief spike, it drops straight back down to knee-high nothingness through the 21st and 22nd, with the energy disappearing again. A 0.3-foot groundswell with a 12-second period shows up on the 22nd, but it’s just a whisper.
So, the verdict is harsh: there’s one okay-ish window on the 20th morning. The rest of the 16 days is a write-off for a decent surf. The water temperature right at the start is 68°, which is a notable 5° warmer than usual for this time of year, so at least the swim will be pleasant.
Alright, that’s the grim picture for Joss Bay. Keep your eyes on that 20th, but otherwise, get the kite gear serviced instead. This is Rusty, signing off.

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.
