The Lowdown
G'day, Rusty here, and I gotta be straight with ya – the next couple of weeks are looking pretty flat at Joss Bay. We’ve got a long stretch of nothing much to get excited about, so let's break it down.
Right off the bat, we've got a gap. From Tuesday 15th September right through to the end of the month, there's not a single wave worth paddling out for. Everything is showing as "poor surf conditions" and the combined wave energy is mostly a measly 0 to 7 (weak). The water temp is sitting at 67°F, which is much warmer than normal for this time of year, but that’s the only highlight.
The first few days are flat with tiny dribbles. Tuesday afternoon the 15th only has 0.3ft of swell from the north with a 5-second period – absolutely woeful. A couple of mornings later, like Thursday the 17th, we get a 0.7ft NNE swell with a 9-second period, but with 22 mph winds, it's messy and not worth suiting up. Friday the 18th and Saturday the 19th just keep the same story: tiny 0.3ft bumps from the north and clean offshore winds, but there's just not enough water moving to surf.
We do get a glassy day on Sunday the 20th, but with zero swell, it’s a total flat spell for the whole 16 days. This area is looking like more fun for kite surfing than paddle surfing if anything kicks up, but right now, even that’s a stretch. The only minor blip comes right at the very end: on Saturday the 26th, we see a 2ft NE swell with a 10-second period and a combined energy of 183 (moderate), but it's cross-onshore and still rated as poor. Then Sunday the 27th bumps up a touch to 4ft from the east, but the period drops to 5 seconds and the energy is 91 (weak). Not a proper wave in the lot, sorry.
Conditions stay quiet right through to Wednesday 30th September, with tiny 2ft and 4ft swells but never any decent quality. It’s a real blank run, which feels more normal for this area when the charts look like this. Forecasts can change, but for now, keep the board in the shed.

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.
