The Lowdown
Alright, Rusty here again.
Let’s be real – this 16-day stretch for Joss Bay is a tough one. There’s pretty much nothing worth paddling out for. It’s a long, flat, and messy gap with no real surf on offer.
Right from the start, it’s grim. Monday the 24th has a tiny 3 ft swell from the east, but a 30 km/h cross-on wind ruins it. The water’s at 69°F, which is 6°F warmer than usual – that’s a big anomaly, like a warm bath, but it doesn’t help the waves. Tuesday the 25th pushes up to 5 ft, but the wind’s onshore and the energy is still only moderate (182). It’s messy and lumpy.
From Wednesday the 26th, it all drops away. Swell falls below 2 ft, and the energy numbers are tiny (38, 22, 6… depressing). The wind does go cross-off and the conditions clean up, but with no power behind it, you’re just bobbing around.
The second week is even worse. From Sunday the 30th through to Tuesday the 8th of September, swells are under 0.7 ft. There are some offshore wind moments, like Saturday the 29th and Sunday the 30th, but with energy at 2 or 1, there’s nothing to catch. It’s clean but empty.
There’s a tiny blip on Tuesday the 1st of September afternoon – a 0.3 ft north swell with a 9-second period and strong offshore wind – but it’s barely a ripple.
Joss Bay is an inconsistent spot, and this is one of those flat runs. Don’t lose hope, forecasts can change, but for now, leave the board at home.
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.
