The Lowdown
Alright folks, Rusty here. Let’s take a look at what Joss Bay has in store for us over the coming days.
To be straight with you, the next two weeks are looking pretty flat and grim for a paddle. There’s a long, dry spell ahead. After a couple of tiny, grovelly days on Thursday the 27th and Friday the 28th, we hit a big fat zero from Saturday the 29th of August all the way through until Monday the 7th of September. That’s a solid 10-day gap with barely a ripple – nothing worth getting wet for. The water temp is sitting at a very unusual 69.1°, which is much warmer than normal for this time of year, but that’s little comfort when there’s no waves.
The only faint pulse of life shows up right at the very end of the forecast. On Tuesday the 8th of September, we finally see a little bump of energy, with a weak combined swell energy of just 16. A 1.6 ft swell from the NNW with a short, snappy 4-second period. It’s tiny and windswell, but there’s a morning window with offshore winds from the W at 19 mph which will keep it clean. It’s not one for the quiver – think more of a longboard or a foiler if you’re desperate. Then on Wednesday the 9th of September, the energy picks up a touch to 39, with a 3 ft swell from the NNE, period still a poor 5 seconds. Again, the morning looks best with a fresh offshore from the WSW. That’s about as good as it gets. Joss Bay is consistently inconsistent and this run of nothing is pretty normal for the area.
For the standout, you’ve really only got one window that’s worth a look. Wednesday morning, the 9th of September. It’s the biggest swell of the whole period at around 3 ft from the NNE, and with a fresh offshore wind it’ll be clean. The period is short though, so expect lumpy, weak lines – not a classic by any stretch. But it’s the best on offer, so if you’re jonesing, that’s your session.
Stay patient, folks. Forecasts can always change.

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.
