The Lowdown
Alright, this is Rusty.
Look, I’m not gonna sugarcoat it for you. The next couple of weeks here at Joss Bay are looking pretty grim for a proper paddle session. There’s a long stretch of flatness or knee-high dribble coming our way, and the swell is just not cooperating. We’re looking at a gap of almost no worthwhile waves from now right through to about the 21st of September, with a few tiny bits of energy that won’t get you out of first gear.
The energy in the water is weak – we’re talking readings as low as 1 (one!) for days on end, which is about as lifeless as it gets. The wind is often offshore or clean which is the only silver lining, but with nothing to blow into shape, it’s a moot point. On the morning of the 16th, we see a bump to 3 ft from the NNW, but the period is a short 4 seconds and it’s still scoring a zero for surf quality. That’s a pass from me.
There is one window that might get your heart rate up, but you need to be patient. On Monday the 21st of September, a pulse of swell shows up. The morning has surf hitting 4 ft from the NE, with a combined energy of 128, which is moderate. The bad news is the wind is a moderate cross-shore creating chop. The afternoon is much the same height, at 4 ft from the NE, with energy up to 138, but it goes cross-on with a light breeze. It’s the biggest surf on offer, but with those wind directions, it’s going to be messy. There’s a bit of a cleanup on the 22nd with lighter winds, but the swell drops to 3 ft.
Honestly, if you’re desperate for a paddle, the morning of the 22nd of September is your best bet. The swell is 3 ft from the NNE with a 6-second period, the wind is light cross-off and the energy is a moderate 51. It’s still nothing to write home about, but you’ll get a few clean, small ones under a clear sky. For the rest of it, I’d save the petrol and wait for a better forecast. With this kind of consistency being so lacking, a blank run is more normal for this area, but it tends not to stay poor for long.
Stay patient,
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.
