The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a 16-day window here for Joss Bay, and I’m not gonna lie to you, it’s a tough one. The surf is flat or tiny for days on end, and when it does show a pulse, the conditions are just off. No real standouts, but let’s walk through the story.
The whole period starts with a hopeless run. From Sunday the 19th of July right through to the end of July, we’re looking at tiny, weak waves with poor surf quality. The combined energy is mostly below 100 (weak), with the highest being just 86 (weak) on Sunday afternoon. Winds are onshore or cross-shore, and the swell is bumpy and short-period. It’s a write-off for a solid week and a half. If you’re a kite surfer, the strong cross-shore winds on the 28th might look interesting, but for a paddle surfer, there’s nothing.
The first real sign of life doesn’t come until the 2nd of August. That Sunday morning, we’ve got a 5ft swell from the NE, with a period of 6 seconds. The combined energy jumps to 162 (moderate). The wind is a clean cross-offshore from the NW, so the surf will be clean. But here’s the catch – the swell is from the NNE, which is a little off the optimum N direction for Joss Bay. The period is short, so it’s going to be a bit fat and weak. The water temperature is 68°, which is a whopping 7° warmer than normal (much warmer than usual for this time of year). The anomaly is over three degrees, which is very unusual. Sunday afternoon is similar, with 4ft swell and 128 (moderate) energy, still clean.
The next morning, Monday the 3rd of August, drops back to 3ft and 38 (weak) energy, with a cross-shore breeze. It’s not a patch on the Sunday.
So, the best on offer is Sunday, the 2nd of August. Joss Bay is inconsistent, and it certainly lives up to that here. It’s a rare opportunity in this window. The swell is 5ft from the NE, with a 6-second period, and the wind is clean cross-offshore. The water is much warmer than normal. The waves will be clean, but don’t expect a long period or a lot of power. The crowds can be a problem, as Joss Bay is often busy, so get there early. The combined energy is moderate (162). It’s not a day for beginners – that 5ft is pushing it – but it’s the only half-decent option in the whole outlook.

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.
