The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for the next 16 days.
Honestly, I’ve got to be straight with you – it’s a pretty grim run. The whole forecast window is a bit of a write-off. There’s just no decent surf to get excited about right now. We’re looking at a solid 16-day stretch with nothing that qualifies as a good option. The only break on the radar is Joss Bay, and it’s not offering anything worthwhile.
The first few days are flat out weak. Thursday the 30th of July, we’ve got a tiny 0.3 ft ripple from the north with a pathetic 8-second period and combined energy of just 1 – that’s about as weak as it gets. Onshore wind from the south at 16 mph isn’t doing it any favours either. The water temp is sitting at 69°, which is a massive 7° warmer than normal for this time of year – that’s very unusual, but it won’t help the waves.
We go through the end of July and into the first week of August with nothing but small, junky waves. Friday morning the 31st sees a 2 ft northerly swell, but with a period of only 4 seconds, it’s just wind chop. Combined energy is 16 – still weak. The wind is a messy cross-shore from the NNW at 12 mph. That pattern just keeps repeating itself: tiny swells, short periods, and poor wind conditions. There’s a morning on the 5th of August that’s glassy, but the swell is only 1 ft – not enough to surf.
The second week doesn’t get any better. We get a bit more energy around the 13th of August, with a 5 ft swell from the ENE and a 6-second period. Combined energy hits 135 (moderate), which is the most we see all window. But the direction is cross-off from the northwest, and the break is described as having poor surf conditions. The afternoon of the 13th pushes 5 ft from the ENE with 171 energy, but again, it’s all filed under poor surf. The wind is cross-off from the south at 12 mph, but the period is short at 6 seconds and the wave quality is just not there.
Look, Joss Bay is inconsistent and rarely breaks properly, and this forecast proves it. There are no good options. For the whole 16 days, every single entry is labelled “poor surf conditions” with a score of zero. It’s a blank run. That’s just how it goes here sometimes – the forecasts can change, but right now, I’d 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.
