The Lowdown
Right, pull up a stump, let’s have a chat. I’m Rusty, and I’ve been staring at the charts for your stretch of coast, and honestly, it’s a bit of a sad story for the next couple of weeks.
First thing to know: the water is sitting at a toasty 69°F right now, which is a massive 7°F warmer than usual for this time of year. That’s very unusual, feels like bath water.
But that’s where the good news ends. We’ve got a long, blank run ahead. For the next seven days, from Sunday the 9th right through to Saturday the 15th, it’s pretty much a write-off. The swell is tiny, mostly under 2ft, with periods under 5 seconds – that’s just wind slop. The wind is either onshore, cross-onshore, or just messy. There’s no quality on offer.
We finally get a little pulse on Sunday the 16th, but the wind swings hard onshore from the northeast at 25 mph, making it lumpy and messy. That’s not surf, that’s a washing machine.
The only real glimmer in this whole sixteen-day window shows up on Monday the 17th. Joss Bay gets a bit of life with a 4ft swell from the northeast, with a period of 6 seconds. The combined energy hits a moderate 114, so there’s some push there. Now, the catch is that it’s a cross-onshore breeze all morning, so it’ll be choppy. It’s not perfect, but it’s the biggest pulse of the entire forecast. Given the break is inconsistent, this might be the one day to paddle out for the more experienced crew if you can stand a bit of chop. That’s about the only standout, and it’s still a fair way off.
After that, Tuesday the 18th morning offers a clean glass-off with a light offshore from the southwest, but the swell drops back to 2ft. It’s clean but gutless.
The rest of the second week fades right back out into tiny waves and poor conditions. There’s really nothing else to get excited about. It’s one of those quiet runs for the area.
Stay patient, keep an eye on the long-range models, but for now, the board stays in the bag.

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.
