The Lowdown
Alright folks, Rusty here. Let's take a good look at what Joss Bay has got cooking for us over the next couple of weeks. Gotta be straight with you, it's a pretty bleak picture for paddle surfing for the bulk of this outlook.
The overall pattern is one of very weak, short-period wind swell, almost always blown out by onshore or cross-onshore winds. The water temp is sitting at 70°F, which is a massive 7°F warmer than usual for this time of year – that’s very unusual, and something you’ll feel when you get in.
We're looking at a long, dry spell with no real surf to speak of right through the end of August. From the 22nd right through to the 31st of August, the energy is just pathetic, with the combined swell energy barely cracking double digits. The best you'll see in that whole first week is a 4ft wave on Tuesday the 25th, but it's getting hammered by a fresh onshore breeze (ENE at 22 mph), making it a total mess. The wave comment says it all: "poor surf conditions" for almost every single session. It’s not even worth looking at the ocean.
We finally get a tiny pulse on the 1st of September. Tuesday morning (1st September) shows a 4ft north swell with a weak 5-second period, and energy at just 64. The wind is a light cross-off from the west at 9 mph, which will clean things up. The wave comment says "surfable waves but very ordinary conditions," so it's not going to be epic by any stretch. It might be the only window in two weeks where you can get a few knee-high, crumbly ones to yourself, but don't expect much.
After that tiny blip, the energy dries up again. The rest of the first week of September shows the swell dropping back to nothing and the wind swinging back onshore, ruining any chance of quality. Even when we get a 12-second period swell on the 6th of September, the wave height is only 0.3ft – that's flat.
If you’re a kitesurfer, there are a few really windy afternoons, especially the 28th and 29th of August with strong offshore and cross-off winds, but the swell is non-existent, so there's nothing to ride. For the rest of us, it's a blank run. The area tends to have spells like this, so it’s not unusual, just disappointing.
Stay patient, check back later. Forecasts change.
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.
