The Lowdown
Right then, let’s have a look at what’s on the cards for Joss Bay over the next couple of weeks. I’ll be straight with you, mate – it’s a pretty grim run. The whole 16-day window is a bit of a write-off, to be honest. There’s no real surf to get excited about; we’re looking at a long stretch of flat, weak, and messy conditions. The energy just isn't there. The water is sitting at 68°, which is much warmer than normal for this time of year, a solid 5°F above the long-term average, so at least it won’t be a cold wait.
The first tiny pulses of energy don't show up until Thursday the 17th of September. Thursday morning we might see some bumpy 5ft waves, but the period is a short, weak 6 seconds, and the combined wave energy is a meagre 141. The wind is light and cross-off, so it’ll be clean, but the conditions are described as ordinary. It’s a beach break that's rarely consistent, so it’s not looking like it’ll offer much. Friday the 18th morning has a bit more height at 6ft, still a short 5-second period, with moderate energy of 179. Again, it’s clean but ordinary. That’s about as good as it gets, which isn’t saying much. With the swell being short-period and the wind light, the shape will be pretty average.
After that, we’re back to tiny, weak, and poor conditions right through until the end of the month. There is nothing here that qualifies as a standout, not even close. For an area that’s as inconsistent as this, a blank run like this is pretty normal. The setup is a beach break, so with these small, weak swells and any sort of wind, it’s not going to be worth a paddle. Honestly, this looks more interesting for the kite surfers than anyone with a paddle board.

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.
