Table - best surf conditions forecast for Joss Bay over the next 16 days.
Alright folks, Rusty here. Let’s have a look at the surf prospects for Joss Bay over the next sixteen days.
Right off the bat, I gotta be straight with you – this is a tough run. The entire forecast window is a write-off for any kind of decent surf. There are no standouts, no hidden gems, nothing to get excited about. We’re looking at a solid sixteen-day gap with no real recommendations.
The first few days, from the 11th through to the 16th, are a total mess. We’ve got a weak, short-period swell from the NE, with heights around 2ft to 5ft, but the wind is relentless. Strong onshore and cross-onshore winds from the NE and E are just shredding any chance of shape. The combined energy is weak to moderate (37 to 163), and it’s all described as “poor surf conditions.” The swell period is a pathetic 4 to 6 seconds, so it’s just bumpy, weak, and unrideable. The water temp is about 68°F, which is *much warmer* than normal for this time of year – a massive anomaly of 8°F – but that doesn’t help the waves.
The middle of the window, from the 17th up to the 22nd, sees a slight drop in swell size, but the conditions don’t really improve. We get a few moments of cleaner, cross-off winds on the 17th and 18th, but the swell is tiny – 1.0ft to 2ft – with barely any energy (3 to 27). It’s not worth paddling out for. The combined energy does pick up again on the 21st and 22nd, hitting 185 and 226, but with onshore winds, it’s just messy and lumpy.
The final few days, from the 23rd to the 26th, are a sad end to the outlook. The swell drops back to nothing, with heights of 0.3ft to 3ft and very low energy (1 to 62). While we do get a bit of offshore wind on the 24th, the swell is simply too small to do anything with. The period is a bit longer on the 24th (7-8 seconds), but there’s no power behind it.
Honestly, this is a classic blank run for Joss Bay. It’s a spot that’s inconsistent, and when the wind is wrong, it’s just not worth it. The setup is a beach break, and with the strong onshore winds we’ve got, this looks more like a kite-surfing window than a paddling one. The forecasts can change, but for now, leave the boards in the car.
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.
