The Lowdown
Alright, Rusty here. Let’s have a look at what’s happening with Joss Bay over the next couple of weeks.
Honestly, I’ve got to be straight with you – this is a rough run. The whole 16-day window is basically a flat spell. There’s no decent surf on the cards at all. The first few days have a little bit of swell, but the conditions are just poor, with strong onshore winds and messy waves. You’re looking at tiny, weak stuff with a combined energy of just 104 (moderate) on the 25th, dropping off fast to nothing. Water temp is 69°, which is a whopping 6° warmer than usual for this time of year – very unusual, like a warm bath in August.
From the 26th of August onward, it’s all tiny, inconsistent blips, with combined energy values in the single digits and zeros. The wind is often howling, with strong offshore breezes that make it clean but impossible to paddle into because there’s no wave to catch. A few mornings have a glassy surface on the 4th of September, but the swell is a pathetic 0.3 ft. You’d be floating.
Joss Bay is an inconsistent spot anyway, and with this blank run, it’s more normal for the area to have long gaps like this. There’s simply nothing to recommend. If you’re desperate for a paddle, maybe a kite would get you moving on those windy afternoons, but for surfing, save your energy.
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.
