The Lowdown
Hey gang, Rusty here. Let’s be honest, the surf situation for Joss Bay for the next sixteen days is looking pretty grim. I’ve been through the numbers and it’s a whole lot of nothing happening out there. The short answer is: we’ve got a big gap of flat, messy water.
We’re starting with a total dud. From Wednesday the 15th all the way through Monday the 21st of July, it’s just poor. We're looking at tiny, wind-blown junk with wave heights under 3 feet and periods so short they’re basically wind slop (around 4 to 5 seconds). The wind is mostly cross or cross-onshore from the NE, so it’s choppy and lumpy. The combined swell energy is weak as water, usually under 50. It’s a no-go zone.
Then we get a little window from Tuesday the 22nd to about Sunday the 27th where the wind swings offshore. On Thursday the 23rd, we even get a morning of glassy conditions. The ocean will look nice, but it’s a total mirage. The swell is tiny—1 to 3 feet—with that same weak, short period. It’s clean enough to look at for a sunset, but there’s zero power. The energy stays under 50, even in those clean conditions.
The last few days, from Monday the 28th of July through to the end, are more of the same. Small, weak, and messy. The swell tries to come from the east, but it’s barely a ripple. The combined energy drops into the single digits. It’s a straight-up flat spell.
If I have to pick a “best” moment, it’s that glassy morning on Thursday the 23rd of July with a 3-foot NNE swell. It’ll be the only time the water is smooth, but there’s no wave to ride. There are no standouts in this forecast. This is one of those rare blank runs for Joss Bay; the swell just isn't coming. We’ll have to wait and see if the forecasts change, because right now, the only thing on offer is a float on a flat day.

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.
