The Lowdown
Alright, Rusty here. Let's get into it for Joss Bay. No two ways about it, this is a tough stretch. We're looking at a 16-day window that's mostly a bust, with a big gap of flat, rubbish conditions right through the middle. The water is sitting at 70°F, which is a massive 7°F warmer than normal for this time of year – that's a real anomaly, feels like a warm bath in the lineup.
The first week is a write-off. From August 12th through the 16th, it's a mess of onshore and cross-onshore winds, mostly from the north and east, with swell heights barely scraping 4ft on the 16th but with a short, weak period of 4 to 5 seconds. The combined energy is low, between 14 and 87 (that's weak wave energy, really struggling to form a proper face). The waves are just chopped up and poor. You'll be battling the wind more than the waves.
We get a bit of a weird shift mid-week. On the 18th, a strong offshore wind from the southwest blows through at 25 mph, but it's on a tiny 0.7ft swell. The energy is a pathetic 6 (very weak). It's clean, but you'd need a wing to get into a wave. The 19th and 20th are similar, with the 20th Thursday afternoon offering the only glimmer of hope. The wind drops to glassy conditions, and a 2ft swell from the north-northeast with a period of 9 seconds pushes the combined energy to 79. The report says "surfable waves but very ordinary conditions." It's the best of a poor bunch, but it's not a standout.
After that, it's back to flatness. The period from the 21st to the 27th is a long, quiet run. Swell heights hover around 0.3ft to 2ft, and the energy never gets above 47. The winds are mostly offshore or cross-off, keeping things clean, but there's just no power in the water. The 27th Thursday morning is glassy and flat as a pancake.
So, the honest truth for Joss Bay over the next 16 days? There's no standout day. The only moment that could be classified as surfable is the afternoon of the 20th, but it's very ordinary. The rest of the time, you're looking at a combination of poor swell and wrong wind. For this area, a blank run like this is more normal than not. Leave the board in the car and watch the tide come in. The setup looks more interesting for kite surfing than paddle surfing for the next week or so, with that strong offshore wind.
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.
