The Lowdown
Alright, Rusty here. Let’s talk about what’s cookin’ at Joss Bay over the next couple of weeks. Straight up – I’ve gotta be honest with ya, it’s a tough stretch ahead. The next 16 days are lookin’ pretty flat and grim for any proper waves. You’ll see a lot of days with tiny to no swell, and when there is a bump, the wind is gonna mess it up.
Right now, Sunday morning the 23rd, we got a tiny 2ft swell coming from the NE, but the cross-onshore breeze from the NNE at 9 mph is makin’ it choppy and ugly. The combined wave energy is weak (31), and it’s just not worth paddlin’ out for. Sunday afternoon ain’t any better – same 2ft, but now the wind is onshore from the East at 12 mph. Just messy.
Monday the 24th, the swell tries to build a bit – 3ft Monday morning, but that East wind cranks up to 22 mph cross-onshore, so it’s lumpy and poor. Afternoon sees 4ft from the ENE, but the wind is howlin’ onshore at 25 mph. Not good.
Tuesday the 25th – we get the biggest push of the whole period: 5ft from the ENE in the morning, with a short 6-second period. The combined energy hits 176 (moderate), so there’s some power, but it’s onshore wind from the East at 19 mph. That’s poor surf quality – big, messy, blown-out waves. Afternoon drops to 4ft with a lighter ESE breeze at 9 mph, but still cross-onshore and choppy.
Wednesday the 26th – finally a glimmer! Morning shows 2ft from the NE, and the wind swings to a light S at 6 mph, giving us clean, cross-off conditions. Combined energy is low (24), but it’s the cleanest we’ve seen. Afternoon stays clean with 1ft from the NE and a moderate S breeze. Still, it’s tiny.
From Thursday the 27th all the way through to Sunday the 7th of September, it’s a desert. Swell drops to 0.3ft or even zero for days. Winds are offshore or glassy at times, but there’s just not enough wave to surf. The water temp is about average for the time of year, so nothin’ unusual there. A few days, like Monday the 31st, are glassy but flat as a pancake.
Bottom line: if you’re desperate, Wednesday the 26th morning is the cleanest option, but it’s only 2ft. Otherwise, this stretch is a write-off for surf. No standouts, no gems – just a lot of waitin’.
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.
