The Lowdown
Alright folks, Rusty here. Let’s get straight into it. The news isn’t great for the next 16 days at Joss Bay—honestly, this is a real flat spell and there’s nothing to get excited about for a long stretch. The water’s sitting at a very unusual 69° – that’s way warmer than normal for this time of year, which is a weird little bonus if you’re just having a paddle, but for surfing? There’s barely a ripple.
The first surf that’s even worth mentioning doesn’t show up until Tuesday morning, 1st September. Even then, it’s only 0.7ft of swell from the NNE, with a period of 7 seconds. That’s short-period, weak stuff, and the combined energy is a measly 4. It’s not going to do anything. The wind is light offshore from the WSW, so the surface will be clean and glassy, but there’s just no wave to ride. That sets the tone for the whole outlook.
We then have a long gap of nothing but tiny, insignificant junk. Most days show 0.3ft or less, with periods of 6 to 7 seconds and energy values of 1 or 2. The wind often blows offshore (WSW or W), which would be great if there was any swell, but there isn’t. It’s a frustrating tease.
A slight bump appears on Tuesday morning, 8th September. We get a 3ft swell from the NE, but the period is a terrible 5 seconds – that’s pure wind chop, no power. The combined energy is 54, which is still weak. The wind is offshore (SW) at 19 mph, so it’ll be clean, but the waves will be lumpy and unrideable for a proper surf. Wednesday morning, 9th September, is a bit better: 1ft from the NE with a 9-second period, energy of 38. Still small, but with a fresh offshore wind from the W, it’ll be clean. It’s a knee-high day at best, and only for the most desperate.
That’s it. There’s no standout period, no solid groundswell, nothing that gets the heart pumping. The whole 16-day window is a write-off for surf. If you’re a kitesurfer, the strong offshore winds later in the period (like the 25-31 mph gusts on 7th and 12th September) might look interesting, but for a surfer? Leave the board at home.
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.
