The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a tough one. The forecast is pretty grim across the whole 16-day window for Joss Bay. There’s a long stretch of nothing worthwhile, and what little swell shows up is so small and weak it’s barely a ripple. Let’s break it down.
We start off with a real dud. Thursday, August 6th, has nothing going on – we’re talking 0.3ft swell from the north with a weak energy score of just 1. Wind is cross-off, but with a wave that tiny, it’s not surfable. Friday and Saturday look equally poor, with the same knee-high dribble and cross-onshore winds making it choppy and messy. The water is a bizarre 70°, which is a massive 7° warmer than normal for this time of year – that’s really unusual, but it doesn’t help the waves one bit.
Sunday the 9th brings a moment of absolute glass, with the wind dropping to nothing, but the swell is still stuck at 0.3ft. It’s a lake out there. The following week, from Monday the 10th through to Wednesday the 19th, is a brutal grind. We get a tiny bump in energy around the 12th, with a 3ft easterly swell and a moderate energy of 53, but it’s all onshore wind and poor conditions. It’s not worth paddling out for.
The only time things get slightly interesting is around Tuesday, August 18th. The swell jumps to 3ft from the north-northeast, with a period of 7 seconds and a combined energy of 114 (moderate). But the wind is onshore, so it’s going to be a bumpy, blown-out mess. That’s not a standout; it’s just the least bad day in a bad run.
The very end of the outlook, on Friday, August 21st, shows a 3ft swell from the east-northeast, with a period of 5 seconds and a moderate energy of 53. The wind is cross-off in the morning and offshore in the afternoon, which would clean it up. But with such a short period and a break that’s *inconsistent* and exposed to the north, this is a long shot. It’s the best on offer, but that’s not saying much. Crowds are likely here, but with conditions this poor, it might be quiet.
Honestly, there’s nothing here to get excited about. For a spot that’s already inconsistent, this 16-day run is a total blank. Keep your board in the car, but don’t hold your breath. Forecasts can change, but right now, it’s a hard pass.
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.
