The Lowdown
Hey folks, Rusty here. I’ve got a look at the next couple of weeks for Joss Bay, and I’m not gonna lie – it’s a tough one. The forecast is showing a real flat spell with no real energy for most of the period. The water temp is sitting at 68°, which is a solid 5° warmer than usual for this time of year, so that’s a bit of a treat if you’re just floating around, but it doesn’t help the waves.
We’re starting off on Thursday, September 3rd with barely a ripple. The combined energy is a measly 0 (zero) in the morning, and we’re looking at a weak 0.3 ft from the north with a 11-second period in the afternoon. That’s clean enough with a fresh offshore wind, but it’s just not doing anything. This pattern sticks around for days. Friday the 4th and Saturday the 5th are similar – tiny 0.3 ft waves, clean conditions, but the combined energy is only 2 to 4. It’s a frustrating stretch for a surfer.
Sunday the 6th sees a bit of a bump, with a 2 ft swell from the southeast, but it’s a shocker – a 3-second period means it’s pure wind chop. The cross-shore wind and combined energy of just 11 won’t save it. The following week, from the 7th through the 17th, is a write-off. We’re talking days of zero to 0.7 ft, some offshore winds keeping it clean, but the energy is mostly in the single digits. It’s just a flat, quiet spell. There’s a glimmer on the 18th of September, with a 2 ft north swell, but it’s only got a 4-second period and combined energy of 13 – still not enough to get excited about.
So, honestly, there’s no standout here. Not a single day offers anything worth paddling out for. The only positive is that the wind is often clean, so if you’re desperate for a float on a longboard, you might squeeze a grovel out of it, but it’s not surf. For this area, a blank run like this is just how it goes sometimes. Keep an eye on the forecasts, they 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.
