The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Joss Bay.
Honestly, my heart sinks a little looking at this stretch. For the immediate future, it’s a long, flat spell. We are looking at a solid 9-day gap from now with absolutely nothing worth paddling out for. The swell energy is bottomed out, often as low as 2 or 1, and the waves are barely a whisper. Don't even bother waxing up for the first week and a half; it’s a write-off.
Things finally try to flicker back to life on the Friday morning of the 21st of August. A little spike of energy comes through – the combined energy hits 78 – with a 3ft swell from the North at a short 5-second period. The wind is cross-offshore and clean, so it will look tidy, but honestly, with that period it's going to be weak and fat.
The best on offer across the whole 16-day window is that Friday afternoon, the 21st of August. We finally see a bit of grunt, with the combined swell energy up to 61 and a 2ft wave from the North-Northeast but crucially it pulses to a 9-second period. It's still small, but the longer period will give it a bit more shape. The wind stays cross-off from the WNW with a gentle breeze, so it should be clean. It’s the only time in the whole run the report says anything other than "poor," so if you're desperate, that's your window. Just don’t expect much.
From there, the energy falls away again into the back half of the month with nothing else standing out. A long, slow period for the bay, I'm afraid.

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.
