The Lowdown
Gather ’round, crew. Rusty here. Let’s have a look at what North Jetty’s got cookin’ over the next couple weeks. I won’t sugarcoat it – this stretch is lookin’ mighty lean. We’ve got a long, drawn-out run of small, weak surf and onshore junk. Don’t get your hopes up too high just yet. The first decent window doesn’t even appear until *Saturday, September 19th*, so we’re staring at a solid gap of over a week with nothing but duds.
Right out of the gate, Friday the 11th through Monday the 14th, it’s tiny. We’re talkin’ ankle-snappers at 1ft to 2ft from the ESE, with periods barely hitting 8 seconds. The combined swell energy is weak, sitting between 28 and 53. Winds are a mix of cross and glassy early, but it’s just not enough to work with. Tuesday the 15th stays flat with cross-onshore wind. Wednesday the 16th and Thursday the 17th see a pulse of short-period ENE windswell pushin’ 5ft to 5ft, but it’s onshore wind at 16 mph – ugly, lumpy, and blown out. Energy climbs to 139, but that’s all with a poor-quality, onshore mess. That run carries through to Friday the 18th with even smaller, wind-affected surf.
Alright, here’s the one glimmer – Saturday the 19th morning. We get a brief moment of glass in the early hours. ESE windswell at 2ft with a weak period of 6 seconds (swell energy only 54), but the wind flips glassy. It’s described as “surfable waves but very ordinary conditions” – that’s the best we get. It’s still small and weak, but if you’re desperate, it’ll be clean for a short window.
Sunday the 20th morning is glassy again, but only 1ft. Monday the 21st through Wednesday the 23rd sees a bigger pulse of short-period NE and ENE swell, hitting 6ft to 7ft on Monday and up to 5ft on Tuesday, with combined energy spiking to 454 on Monday afternoon. But here’s the kicker: it’s all blown out with onshore or cross-onshore winds howling at 12 mph to 25 mph. That’s not for surfing – that’s kite territory. The swell is there, but the quality is tanked. This setup looks more interesting for kite surfing than paddle surfing. After that, the rest of the run into late September fades back to tiny, weak surf with light onshore winds.
So, what’s the call? The only true standout is Saturday the 19th morning. It’s small, but glassy and clean. It’s the best on offer. For the rest of the forecast, you’re better off waitin’ for a better window. Don’t hold your breath.
Stay salty,
Rusty

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