The Lowdown
Right, let’s have a look at what’s on the cards for the next couple of weeks around here. I’ll be straight with you, it’s looking pretty grim for a good stretch. The only break we’ve got to talk about is Joss Bay, and the honest truth is, for the foreseeable future, it’s just not offering anything worth paddling out for. We’ve got a long, dry run of poor surf conditions stretching all the way from now through to the end of the month. That’s a solid two-week gap with nothing to get excited about. Don’t shoot the messenger.
Looking at the early part of the period, from the 13th right through until the 23rd of September, the swell is basically non-existent. We’re talking tiny, inconsistent bumps that just aren’t doing anything. The wind is often offshore or clean, which is a shame because there’s no power behind it. The combined energy is consistently in the low single digits (0 to 7), which is about as weak as it gets. It’s a real shame, because the water is sitting at 67°, which is much warmer than normal for this time of year—that’s a solid 4° above average, so at least you wouldn’t be cold while you’re sitting there on a flat day.
Then, things get a bit weird. Around the 24th and 25th of September, we finally see some swell push in. The combined energy jumps into the low hundreds (111 to 123), so there’s moderate energy out there, and the swell height hits around 5 ft from the N to NNE. But—and it’s a big but—the period is short, around 5 to 6 seconds, so it’s windswell, not groundswell. And the wind is a fresh cross-onshore, making it lumpy and messy. The surf quality is still rated as poor. That kind of setup with that much wind and a beach break is honestly more interesting for kite surfing than paddle surfing. It’s not for us.
The final few days, the 27th and 28th, see the swell dropping back down again with onshore winds, so there’s nothing to salvage there either. Joss Bay is inconsistent at the best of times, and this is one of those blank runs that just happens. Forecasts can change, but right now, there’s nothing on offer.

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.
