The Lowdown

Alright, Rusty here. Let’s have a look at what’s cookin’ for Joss Bay over the next 16 days.

Right off the bat, I’ve gotta be straight with you – the outlook is a bit of a tough one. We’re looking at a long, dry spell with very little surf on offer. The whole 16-day window is a flat stretch, with nothing that shapes up into a proper ride. The first decent bit of energy we see is a tiny 0.3ft pulse from the north on Thursday morning, but that’s it – combined energy is a weak 1, and it’s just not enough to get excited about. The water temp is sitting at 70°, which is a whopping 7° warmer than usual for this time of year – that’s very unusual, almost like a warm bath, but unfortunately the waves aren’t keeping up.

We roll into Friday the 21st with a bit more size, around 3ft from the north, but the period is a short 5 seconds and the wind is cross-onshore, so it’s choppy and messy. That’s a no-go for me. Saturday the 22nd is similar – 3ft from the north, but cross-shore wind and a period of 5 seconds, just not clean. The energy bumps up to 45, but it’s still poor surf conditions.

Sunday the 23rd offers a little hope with 1ft from the northeast and a gentler offshore wind from the west, which keeps it clean, but the swell is tiny and the period is only 8 seconds. It’s a weak 18 energy. Not worth paddling out for.

The middle of the week – Monday the 24th and Tuesday the 25th – we see a bit more size, with 4ft from the east on Tuesday, period of 6 seconds, and combined energy jumping to 176. That’s moderate energy, but the wind is fresh cross-onshore and lumpy. The surf is poor, and honestly, with that short period and onshore wind, it’s more of a kite-surfing setup than a paddle session.

From Wednesday the 26th right through to the end of the forecast on Friday the 4th of September, it’s pretty much a flatline. Swell heights drop back to 0.3ft, periods are short, and the energy is down to single digits. Even when the wind goes offshore, it’s too strong and the waves are just too small. There’s a 10-second period pulse on the 30th of August and 31st, but the swell is still only 0.3ft – that’s a whisper, not a wave.

So, the bottom line: there are no standouts here. The best on offer is probably Tuesday the 25th if you’re desperate, with 4ft from the east, but the wind is lumpy and it’s a beach break, so it’s not going to be pretty. Joss Bay is inconsistent, and this stretch is a classic example of a blank run. It’s more normal for the area to have these quiet spells, so don’t lose hope – forecasts can change, but for now, leave the board at home.

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.
