The Lowdown
Right, folks, Rusty here. Let's have a look at what's shaking for the next sixteen days. Honestly, I gotta be straight with you – it's a pretty bleak picture for Joss Bay. The whole period is a series of small, weak swells, and most of the time the wind is gonna be messing things up. It’s one of those stretches where you're better off finding something else to do.
The bad run kicks off straight away. We've got nothing really surfable for the first week. Sunday the 9th through the middle of the following week is just tiny little waves with strong onshore or cross-onshore winds. The combined swell energy is pathetic, barely tickling the 50 mark. It's just not on.
There are a few fleeting moments where things look slightly less terrible. On Friday the 14th, we get a brief reprieve. The morning is totally glassy, but the swell is a tiny 1 ft from the ENE with a short period. It’s not worth paddling out for. Then again on Monday morning the 17th, we see a glassy wind with a 1 ft swell from the NE. Clean as a whistle, but still only about 14 points of combined energy. It's enough to float a longboard, but I wouldn't call it a session.
The second week is even more of a write-off. After a couple of clean but tiny afternoons on the 18th, we get a blast of strong, messy wind from the 21st right through to the end of the period. Swell practically disappears, with energy readings dropping to zero. The wind is howling at 25 mph from the northeast, just making a mess of everything.
The truth is, Joss Bay is inconsistent at the best of times, and this run looks more normal for the area than anything exciting. I can't even point you to a best day, because there isn't one. Keep an eye on the charts, but for now, I'd say give the surf a miss.
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.
