The Lowdown
Alright folks, Rusty here. Let's have a look at what's cooking.
Honestly, it’s a tough stretch ahead for Joss Bay. We’re staring down a very long run of flat, poor-quality surf that will test the patience of even the most dedicated local. The first week and a half is essentially a write-off, so don't get your hopes up.
Starting off Thursday afternoon, 20th August, we've got a tiny 0.3ft ripple from the north. The wind is howling from the WSW at a solid 22 mph, and with a storm risk, it's just not worth paddling out. The water is at 70.3°, which is a whopping 7° warmer than average for this time of year – very unusual, you'll be sweating in your wettie more than surfing. There’s barely any energy in the water (combined energy of just 1). The rest of August and into September looks equally bleak. We get some small 3.3ft to 4.9ft bumps, but they're ridden with onshore or cross-shore winds that make it choppy and lumpy. Even the clean days around the 26th and 27th August produce nothing but ankle-biters of 0.3ft to 1.3ft.
There's a flicker of hope right at the very end of the forecast period, on Tuesday afternoon, 1st September. A solid 5.6ft swell from the north-northeast shows up, packing a lot more energy (149). The wind goes strong offshore from the west at 25 mph, which will keep the surface glassy. However, this is a strong offshore, which can make paddling into a real battle. This is the only standout in the entire window, and it's a long way off, so take it with a grain of salt. That's a lot of waiting for one afternoon that might be more of a wrestle than a cruise.

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.
