The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Joss Bay.
Honestly, the next couple of weeks are a real test of patience. We’ve got a long stretch of flat, poor surf or tiny, messy waves. From Tuesday the 8th to Monday the 21st of September, it’s pretty much a write-off. The swell energy is basically zero or just a few piddly numbers – we’re talking combined energy as low as 1 up to 27 – and the wind is often cross or cross-off, not doing us any favours. There are a few small pulses around the 16th and 17th, but they’re weak and short period, with messy conditions. It’s one of those stretches where you’re better off checking the kite scene if you’re into that, because the paddle surfing is a no-go.
Then, after all that waiting, things finally wake up on Monday the 23rd of September. That’s the standout. Joss Bay itself wakes up with a proper pulse. Swell from the ENE hits 7 ft, with a period of 7 seconds. The combined energy jumps right up to (374) – that’s a solid, grunty amount of power. Now, it’s not a long-period groundswell, but for this spot, that’s a chunky wave. The water is still much warmer than usual for this time of year, so that’s a bonus. The wind goes light offshore from the SW, and it’s clean. This is for the experts, though. At 7 ft, it’s a serious step up, not for the faint of heart or the beginners. The break is inconsistent, so you’ll be waiting for the sets, but when they come, they’ll be worth it. Crowds are likely, as it’s a popular spot, but with the waiting game, it’ll be a bit more spread out. For the Monday morning and afternoon, this is the only true call on the whole board.
The rest of the window after that looks like it drops back off pretty quickly, so make the most of that one day.
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.
