The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming our way.
Honestly, it’s a pretty bleak stretch ahead. For the first week and a half, there’s barely a whisper of decent surf. The energy is just not there, and the wind is mostly in the wrong spot. The whole period starts with a long gap of poor conditions. We’re looking at days of nothing worth paddling out for, with tiny, weak swell and messy, cross-onshore winds. It’s frustrating, but it happens.
The first real glimmer of hope – and I mean the only one worth talking about – shows up on Friday, 4th September at Jetty-4. That morning, the stars finally start to line up, but only just. We’ve got a clean 3 ft swell rolling in from the SSE, with a 12-second period, which gives it a bit of push. The combined energy is a solid 323 (moderate wave energy), and with a gentle offshore breeze making it clean, it’s the standout. The water is a touch warmer than normal for this time of year, sitting at 74°, which is a nice bonus. The swell direction is a good match for the break’s optimum from the SSE. Just keep in mind the crowds can be a problem here sometimes. This is your best bet, hands down, but it’s a one-morning window. The afternoon chops it up again.
Before that, there’s a brief moment on Saturday, 5th September morning with a similar 3 ft SSE swell and clean conditions, but the energy is much weaker at 207. It’s a back-up plan, not a standout.
After that, the forecast gets ugly again with strong winds and rain. So, if you’re keen, circle that Friday morning on the 4th. It’s not a world-class swell, but it’s the only clean surf on the menu.
That’s it from me. Get out there if you can.
Rusty.

Information about the Jetty Surf forecast
The above surf forecast table for Jetty provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jetty can be found by selecting the local surf guide option on the grey menu. Our Jetty 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 (Jetty) 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 Jetty 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.
