The Lowdown
Alright, let's have a look at what's on the cards for Joss Bay over the next couple of weeks. I won't sugarcoat it; the forecast is pretty grim for the entire 16-day stretch. There are no standout sessions to point you towards, and the score for every single period is a flat zero. It’s one of those rare blank runs where the ocean just isn't cooperating.
The water temp is sitting at 70°, which is a whopping 7° warmer than usual for this time of year at Joss Bay. That’s very unusual, but it’s about the only interesting thing going on.
Right from the start on Thursday the 13th of August, we’ve got tiny 1ft swell from the ENE with a short, weak period of just 4 seconds. The wave energy is almost non-existent (7). The wind is onshore from the east, and the report says it's "poor surf conditions." That’s the story for the rest of the day and into Friday.
Friday the 14th through to the end of the first week sees the swell dropping to zero, with absolutely no wave energy. Even on the 15th and 16th, when a small 2ft to 3ft bump shows up from the NE, the period is a paltry 3 to 5 seconds, and the wind is cross-onshore, keeping things choppy and poor. The combined wave energy peaks at a weak 31 on Sunday the 16th, which is nothing to get excited about.
The second week doesn't offer any hope. We go through days of tiny surf, onshore winds, and zero scores. There’s a slight uptick in size on Monday the 24th of August, with a 5ft swell from the north hitting in the afternoon, but it’s onshore and labelled "poor surf conditions." Then on Wednesday the 26th, the swell builds to 6ft from the NNE, and the combined energy jumps to 277 – the highest we’ll see. But that's coming with a 22 mph onshore wind in the morning and a strong 25 mph cross-onshore in the afternoon. At that size, it’s getting too big for beginners, but with those winds, it’s just going to be a messy, blown-out wall for anyone else. Honestly, with that kind of wind and a beach setup, it looks more interesting for kite surfing than paddle surfing.
The rest of the week fades back to tiny, choppy, and poor conditions through to the 28th of August. There’s just no window of clean surf to recommend. It’s a long dry spell, so don’t hold your breath. Forecasts can change, but for now, this stretch is a write-off.

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.
