The Lowdown
Alright, let’s call it as it is. Joss Bay is looking at a real drought for the next two weeks. There’s barely a ripple to get excited about, and what small bumps do show up are weak and poorly shaped. The water’s a warm 71°, which is way above the average for this time of year, but that’s small comfort.
From Wednesday the 19th through the end of the week, it’s flat. We’re talking 0.3ft waves out of the NE with a 6-second period, and the energy is a measly 1 (weak). Even with clean offshore breezes, there’s nothing to surf. The weekend of the 21st and 22nd brings a tiny bit of size, up to 3ft, but it’s short-period windswell from the NNE, and the wind is cross-on, making it lumpy and choppy. It’s a no-go.
The flat spell continues. Monday the 24th sees a bit more push with a 4ft swell from the E, but it’s onshore and messy. Tuesday the 25th is the biggest swell of the run – 5ft from the NE, with the combined energy at 163 (moderate). But it’s a short 7-second period, and the wind is a strong cross-shore, creating a messy cross-chop. That’s more of a kiteboarding setup than a surfing one. After that, it’s back to flatness into early September, with clean offshore winds but no swell to use them on.
If you’re really looking for something, the morning of Tuesday the 25th has the most size, but you’ll be dealing with a strong cross-shore wind. For clean, rideable waves, you’re out of luck. There’s no standout, just a long, blank stretch.

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.
