The Lowdown
Alright, listen up. It's looking like a flat spell for Joss Bay over the next couple of weeks. To be honest, there's nothing on the table that gets me fired up. I've gone through the numbers, and there's not a single day that I'd call a “go” day. It's a drag, but it's part of the game. The good news is that things can change quickly, and given how this spot can fire, I wouldn't count it out just yet.
The story is simple: a lot of tiny, weak swell and a lot of wind putting chop on it. The first few days are poor. Sunday the 9th has a tiny 0.7ft swell with a 3-second period, which is just junk. The water is running about 7°F warmer than normal for this time of year, which is a big deal when you first get in. Monday and Tuesday are similar, with small, short-period waves and onshore winds ruining any chance of a clean face. The energy is weak, with readings of 2, 10, or 11, which is just about nothing.
There's a brief window around the 14th where the wind goes light and offshore, and the ocean cleans up. But it's tiny—0.7ft to 1ft—and with a 4-second period, there's just no power. It's a classic “looks good, but does nothing” situation. You'd be floating around more than surfing.
The biggest bump in size comes around the 16th, with waves reaching 4ft. But it's coming from the northeast, which isn't the right angle for this break, and the wind is a fresh cross-onshore, making it lumpy and messy. The energy gets up to a moderate 77, but the quality just isn't there to make it work.
After that, it fades fast. By the 18th and 19th, we're talking about ankle-slappers at 0.3ft. There's a little pulse around the 23rd, with 3ft on the cards, but the wind is screaming at 25 mph and it's onshore. That looks more like a kite-surfing session than a surf session to me.
So, bottom line: there are no standout days here. No day where I'd say, “That's the one.” If you're keen, the cleanest waves will be on the 14th, but you'll be scratching for a ride. Otherwise, keep an eye on the charts, keep the wax on, and maybe practice your duck dive. This flat spell won't last forever.

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.
