The Lowdown
Alright, Rusty here. Let’s get into it for Jetty.
Honestly, it’s a rough stretch ahead. We’re looking at a long, quiet run with barely any worthwhile surf on the cards for the whole 16-day period. The first time we see even a hint of something surfable is Thursday morning, 11th of September, and even then it’s only a marginal call.
The overall pattern is dominated by weak swell and dodgy wind. For the first week and a half, it’s all small, short-period slop. The days from September 1st through to the 10th are basically a write-off – wave heights stay under 4ft, and the wind is almost always cross, cross-on, or onshore, chopping things up. You’re looking at scores of zero for that entire stretch. The combined swell energy is mostly low, often in the double digits (like 25 to 219), which confirms there's just no power.
The one tiny flicker of hope comes on Thursday morning, 11th September. The wind goes glassy – 0 mph – and we get a 4ft swell from the SSW, with a period of 6 seconds. That’s a short-period swell, so it won’t have much push, but the glassy conditions will make it look clean. The combined energy reads a moderate 137, and the commentary calls it “surfable waves but very ordinary conditions.” It’s definitely the best we’ll see, but that’s not saying much. That morning is the absolute standout, and it's only for the hardcore who just need to get wet.
After that, it’s back to small, messy, and poor conditions right through to the 16th of September. There are no other standouts. For a break that’s *very consistent*, this is a frustratingly blank run.
Water temperature at the start of the period is 72°, which has a positive anomaly of 2° – so it’s just a touch warmer than usual for the time of year.
So, if you’re desperate, the dawn patrol on Thursday the 11th is your only real chance. Keep your expectations low, and maybe just wax the board for the sake of it.
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.
