The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Joss Bay.
Truth is, it’s a pretty flat and quiet stretch ahead. The whole 16-day window is a bit of a struggle. There’s no real swell to get excited about, and the conditions are largely messy. We’re looking at a long gap with no real recommendations, so don’t expect much.
For the first few days, from Friday the 7th through to the end of the first week, it’s all tiny waves. We’re talking nothing above 3ft, and the energy is low. The water temperature is 69°F which is much warmer than usual for this time of year, about 7°F above average, so that’s a real treat if you’re just having a dip. The wind is mostly cross or onshore, so the surf is choppy and just poor. The best looking morning might be Sunday the 9th, with a glassy 1.0ft wave from the ENE, but it’s a tiny little thing with hardly any energy (3). Not really worth paddling out for.
The middle of the week, around Tuesday the 11th and Wednesday the 12th, sees a tiny bump in swell height up to 3ft, but it’s short period (4-5 seconds) and the wind is howling onshore. The energy is still very weak (50 at best), and the comment says it all—poor surf. It’s going to be a washing machine. For experienced surfers, the 4ft forecast on Saturday the 15th might sound interesting, but the period is still short, it’s onshore, and the energy is still weak (90). It’s not worth the drive.
The second week is even more hopeless. From the 17th onward, the swell drops back to a tiny 0.3ft to 1.0ft. The wind is often onshore or cross-onshore, and the energy is practically nothing. There’s a glassy moment on the morning of Monday the 17th, but with a 1.0ft wave from the NE and an energy of 3, you’d be better off taking a longboard out for a paddle, not a surf.
Honestly, there’s no standout period here. The break is inconsistent and rarely breaks with any quality. The swell direction is off, the wind is wrong, and the energy is just too weak to do anything with. It’s a blank run for the area, and it’s not unusual for Joss Bay to go quiet like this. Keep an eye on the forecasts, though—things can change.
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.
