The Lowdown
Alright, folks, Rusty here with a look at the Jetty. Let's be straight with each other—this isn't a classic run of form. The Jetty is a breakwater setup that needs a decent SSE groundswell to really get going, and for the next couple of weeks, it's mostly slop.
For the first week or so, starting Sunday the 13th, we've got a little bit of energy, but nothing to write home about. We're looking at small, short-period swell—around 3ft from the SSE on Sunday (67 combined energy), but it's coming with heavy rain and cross-off wind. Yeah, you'd be out there for the love of it, not the glory. A few windows pop up, like Monday the 14th morning with a screaming 19 mph NNW offshore on a tiny 1ft SE swell (46 energy). It would be glassy, sure, but there’s just not enough size to get a proper ride.
The real story is a gap with next to no decent surf from Tuesday the 15th right through until late on Thursday the 24th of September. There's a few brief moments of glass—like Wednesday morning the 16th, with 2ft and light SE wind (75 energy)—but it's gutless and inconsistent. Most of this period is just poor conditions with onshore or strong cross-winds and a lot of chop.
Now, you have to be patient, because the standout session looks to be Thursday the 24th of September, afternoon. This is a week and a half away, so keep your expectations in check, but the charts are pointing to something worth waking up for. We get a clean 4ft swell from the ESE with a proper 11-second period (265 combined energy). And the wind? A light offshore from the north at 6 mph. That means glassy, lined-up waves at the Jetty. This is the one bright spot in the whole forecast.
After that, it drops back off into the small stuff from Friday the 25th, with a long gap of not much until Monday the 28th, which offers a scrappy 4ft easterly swell (109 energy) with light cross-off wind.
Honestly, apart from that Thursday afternoon window, it's a lean stretch. For the serious surfers, mark the 24th. For everyone else, maybe bring a book.

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.
