The Lowdown
Right then, I'm Rusty, and I've been staring at the charts for Joss Bay, and I gotta be straight with you – it's a tough stretch ahead. This isn't a time to be getting your hopes up for a classic session.
We've got a long, long gap of flat, weak surf to start. The whole week from Monday the 31st of August right through to the 10th of September is pretty much a write-off. The combined energy is barely registering, with swell heights hovering around a pathetic 0.3ft to 0.7ft. It’s just flat. Even though the wind is often clean or offshore, there's nothing to ride. You'd be better off with a longboard and a good book.
The first real sign of life, and I mean a small one, pops up on Friday morning the 11th of September. We get a pulse of swell from the NNE, pushing 4ft high. It's short-period stuff though, only 5 seconds, so it'll be a bit crumbly and fat. The combined energy jumps up to 51, which is at least a number we can work with. Wind is a cross-off from the NW, so it'll be clean. But that 4ft is nothing special.
The afternoon of the 11th is actually the most interesting day of the whole run. That same NNE swell builds, still 4ft, but the period stretches to 7 seconds and the energy rockets up to 175. It's moderate energy, but it's the best we'll see. The wind goes cross-shore from the north, which will keep it rideable. For a spot that is often inconsistent, this is the one window where it *might* actually be worth a look. The water temp is sitting at a very unusual 69° – about 6° warmer than normal for this time of year – so you won't need a thick suit.
After that brief flash, it's back to the doldrums. Saturday the 12th drops off fast with weak onshore wind, and then we're back to tiny, inconsistent dribble right through to the 15th of September. There’s nothing else that even comes close to being a standout.
So, bottom line: you’ve got one, maybe two, sessions to look at. The 11th of September, afternoon, is the best on offer – just don't expect a world-class day. For the rest of it, you’re better off waxing your board and waiting.
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.
