The Lowdown
Alright folks, Rusty here. Let’s look at the outlook for Joss Bay. I’ll be straight with you – this one’s a tough stretch. The forecast over the next 16 days is a real struggle for any decent surf. The combined wave energy is weak, barely cracking double digits at best, and there’s no real swell to speak of. We’re looking at a long, dry run with nothing worth getting wet for.
The first few days are a washout. From Wednesday the 5th through to the end of the first week, we’ve got tiny, weak waves. The swell is barely above flat, with a combined energy of just 2 (poor surf conditions) and a period of 6 seconds on Wednesday morning. The wind is howling from the SW at 19 mph, making things messy. This continues right through the weekend. The best you’ll see is a tiny 1 ft bump from the NNE on Monday the 10th morning, but the period is a pathetic 3 seconds, and the combined energy is only 7. It’s just not worth the effort.
The following week doesn’t get much better. There’s a slight uptick on Wednesday the 12th morning with a 2 ft swell from the east, but it’s short-period (4 seconds) and choppy with a cross-onshore wind at 16 mph. The energy is a bit more noticeable at 19, but the quality is poor. The only real sniff of something better comes on Monday the 17th morning. We get a 2 ft swell from the north, with a period of 4 seconds and a combined energy of 17. The wind is a clean cross-offshore from the WNW at 12 mph, which is about as good as it gets here. It’s still small, but it’s the best-looking window in the whole forecast. After that, the forecast goes flat again.
Given the persistent poor surf quality, mostly onshore winds, and the tiny, weak swell, this setup looks more interesting for kite surfing than paddle surfing. The water temperature is about average for the time of year, so no surprises there.
Stay tuned, folks. It can’t stay this flat forever.
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.
