The Lowdown
Alright, Rusty here again, looking at the same deal for Joss Bay but in feet and Fahrenheit.
The window’s quiet right through to mid-September. Most days show flat or ankle-slappers, with combined swell energy reading zero or single digits. Nothing to get excited about.
The first real chance of a wave is Thursday the 17th of September. Morning brings a clean offshore wind from the SW and a swell running about 4 ft from the NE. The combined energy is still weak at 61. Water temp is 68°, which is 5° warmer than normal – that’s pretty unusual for this time of year. The swell is short-period (5 seconds) and onshore to the beach, but the offshore wind will keep things clean. It’s small and weak, only really worth it if you’re just starting out or dying for a paddle.
Through the second week, it stays tiny. The 23rd of September gives another bump – 3 ft NE swell, again short period (5 seconds), with a clean offshore wind from the W in the morning. The energy reading is 41, still weak. Decent enough to get wet, but nothing worth writing home about. The afternoon holds similar with a moderate offshore from the SW.
There’s no standout session here. The best bet is the morning of the 17th of September, but that’s more of a “least bad” option. The break is inconsistent, and crowds are often around – though with waves this small, you’ll likely have it to yourself.
If you’ve got the itch, the 23rd of September morning is your best shot for a clean, tiny wave. Otherwise, I’d sit this one out.
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.
