The Lowdown
Alright folks, Rusty here. Let me level with you about the next couple of weeks at Joss Bay (Joss-Bay). It’s a grim picture, and I’m not going to sugarcoat it. The surf forecast is pretty much a write-off for the entire 16-day window.
We kick off on Thursday afternoon, 27 August, with a tiny 2ft swell from the ENE, but the period is a weak 5 seconds and the combined swell energy is a measly 18 (weak). The water is a notable 69°F, which is 6°F warmer than usual for this time of year – that’s much warmer than normal, and you’ll feel it. But you won’t be riding anything decent; the conditions are poor. The light breeze from the SSW is a cross-off, so it’s clean, but there’s just no power in the water.
From there, it goes downhill fast. Friday the 28th through to almost the end of the forecast period on 11 September, we’re looking at swell heights that barely scrape 2ft, periods mostly under 8 seconds, and combined energy values that are either 1 or stuck in single digits. It’s a long stretch of nothing – days of flat, weak surf with occasional offshore winds that will keep the surface clean, but there’s no wave to ride. The swell is short-period and weak, and even when we get a moderate offshore breeze, like on Friday morning the 28th with 12 mph SW winds, the swell is only 1ft from the NE. It’s just not enough.
Even when we see a little bump on Wednesday morning, 2 September, with a 2ft swell from the NNW and a period of only 4 seconds, the energy is still only 8 (weak). It’s junk. The inconsistency of Joss Bay really shows here – it rarely breaks well, and this run is a total blank. The best I can say is that the wind is often offshore or cross-off, so if you just want to float around on a clean surface, go for it. But for actual surfing? Forget it. There’s not a single standout session in the whole 16 days. The setup looks more interesting for kite surfing than paddle surfing given the persistent wind and lack of swell.
The long and short of it: this is a dead period for Joss Bay. Don’t bother packing a board.

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.
