The Lowdown

Alright folks, it’s Rusty here with your Joss Bay look ahead. Let’s be honest right from the start – this is a flat spell with nothing to get excited about. The whole 16-day window is a write-off for any kind of decent paddle surfing. We’re looking at tiny, weak dribbles the entire time, and a whole lot of nothing in between.

First up, the pattern: For the entire run, from Tuesday 15th September right through to the end of the month, the wave energy is pitiful. You’ve got combined swell energy values barely registering, mostly in the single digits or low 20s – that’s basically zero energy (0 to 33). The summary swell heights never crack three feet; we’re talking 0.3 ft to 3 ft at best, and even those tiny bumps come with a horrible, short period below 8 seconds, meaning no power and no shape.

On Tuesday 15th and Wednesday 16th, it’s a total flat spell – combined energy of 0 or just 1. By Thursday 17th, we see the only real “bump” in the whole forecast, with a 0.7 ft swell from the NNE at a period of 9 seconds, producing a combined energy of 7. But that is buried under a fresh offshore wind from the WSW at 22 mph. It’s too weak to do anything with. The rest of the first week is similar: 0.3 ft waves and onshore or cross-off winds.

Moving into the second week, around Monday 28th September, there’s a tiny pulse of long-period swell (11 seconds!) from the N, but it’s only 0.3 ft high with a combined energy of 3. That’s the definition of “tease” – it has the period of a groundswell but zero size to push it. A long-period swell that small is just a wobble on the water. Plus, it’s straight onshore from the East at 19 mph, making it choppy and messy.

The only thing worth noting is that towards the end of the month, winds get strong and onshore, with a bit of push on the 26th and 27th (3 ft to 3 ft from the East, but with periods of only 4 seconds and onshore winds from the NE). That combo of short, weak windswell and strong onshore breeze is more interesting for a kite surfer than anyone with a paddleboard. Joss Bay is a fairly exposed break, but with zero quality on offer, it’s not worth the trip.

Honestly, for Joss Bay, this kind of blank run is a normal part of the season. It tends not to stay this poor forever, but for this forecast window, the message is clear: leave the board at home.

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.
