The Lowdown
Alright, let’s get this straight: Joss Bay (Joss-Bay) is looking at a pretty grim 16-day stretch. The water temperature is sitting at 69°, which is a massive 6° warmer than usual for this time of year – that’s seriously unusual, like swimming in a bath compared to normal.
Right now, from Saturday the 29th of August all the way through to the middle of September, there’s a near-total lack of surf. We’re talking flat spells, tiny swell, and a lot of wind. The wave energy is in the dumps – mostly just single-digit values (2, 1, 0, 3, etc. – weak energy). The largest swell we see anywhere in the whole run is 3 ft on the morning of Thursday the 10th of September, with a short period of 4 seconds and combined energy of 26 (still weak). Even then, the wind is a cross-off, but the quality is described as poor surf conditions.
For almost the entire outlook, the best calls are clean, offshore wind days, but with wave heights of 0.3 ft to 0.7 ft, there’s simply nothing to ride. On a few occasions, like Monday the 31st of August morning and Friday the 4th of September morning, the offshore wind is strong (25–28 mph), which would make it hard to paddle into anything, even if there was a wave. The peaks are few and far between.
The only slight glimmer comes on the morning of Thursday the 10th of September, when we see 3 ft of swell from the NNE, with a short period of 4 seconds and combined energy of 26 (weak). The wind is a fresh cross-off from the south at 19 mph, so it’ll be clean. But let’s be real – 3 ft with a 4-second period is not going to produce much. It’s barely a ripple.
The afternoon of Thursday the 10th sees 2 ft from the NE with an 8-second period and combined energy of 41 – still weak. Then Friday the 11th of September morning has 1 ft from the NE, 8-second period, with a fresh offshore wind from the SW. It’s clean, but tiny.
After that, it’s back to flatness. The entire second week is a total write-off. There’s no standout session, no day to circle on the calendar. If you’re looking for a silver lining, the water is unseasonably warm, but that’s about it.
Honestly, this is a stretch of nothing. For a break that’s inconsistent at the best of times, this run of poor surf is more normal for the area. Forecasts can change, but right now, there’s nothing to get excited about. I’d be checking back in a week or so.

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.
