The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the outlook for Joss Bay over the next 16 days is a bit of a bummer for paddle surfing. We’re looking at a long, dry spell with hardly any surf worth getting excited about.
For the first ten days, from Wednesday the 15th to Friday the 24th of July, it’s pretty much a write-off. The swell is tiny, mostly under 3 feet, and what little energy there is (combined energy values are weak, often in the 10-70 range) is coming from the NE with a short, weak period around 4-7 seconds. On top of that, the wind is almost always a messy cross-onshore, making for choppy, lumpy conditions. The waves are just poor. There’s nothing here for a surfer.
We finally see a glimmer of hope on Saturday the 25th of July. The morning brings a glassy, clean start with the wind dropping to nothing. The swell bumps up to 5 feet from the NNE with a 6-second period, and the combined energy jumps to 151 (moderate). This is the only real standout window in the entire forecast. However, it’s a short-lived window. By the afternoon, the wind swings onshore and ruins it. The swell is also a bit short-period for the size, so it’ll be a bit fat and closing out, not a classic peak.
After that, we get a few days with offshore winds from the 26th to the 30th, but the swell drops away to nothing, with heights under 3 feet and energy levels falling back to weak. It’s clean but flat.
Honestly, for Joss Bay, this is a tough run. The only window worth paddling out for is the morning of Saturday the 25th. Get there at first light for the glassy conditions and a bit of 5-foot swell. It’s not perfect, but it’s the best we’ve got. The rest of the time, you’re better off saving the wax.
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.
