The Lowdown
G’day, Rusty here. Look, I’m not gonna sugarcoat it—this stretch at Surfside Jetty is looking like a proper flat spell for the next couple of weeks. We’ve got a long gap ahead with pretty much nothing worth paddling out for, so if you’re hanging for a wave, maybe keep the board in the car and wait for a better day.
Starting now, Saturday the 12th of September, the water’s a balmy 71°, which is much warmer than normal for this time of year—so at least the swim’s nice. But the surf? Tiny 2 ft from the southwest, with the combined energy sitting at a weak 143. The wind’s blowing straight onshore, and the report’s calling it poor surf conditions. Not a single reason to get wet.
Sunday the 13th? Still poor. The morning has a 3 ft west swell, but it’s a short 7-second period and cross-on wind makes it messy. The combined energy’s only 150. Afternoon drops to 2 ft, still poor. Monday the 14th brings a little more energy—243 in the morning and 239 in the afternoon—but those are moderate numbers, and the swell’s tiny (1 ft and 3 ft). The cross and cross-on winds keep things choppy.
Tuesday the 15th, Wednesday the 16th, Thursday the 17th—it’s more of the same: poor surf conditions across the board. The combined energy wobbles between 161 and 280, but with swell heights barely cracking 2 ft and winds never lining up, there’s nothing clean.
Friday the 18th and Saturday the 19th see the combined energy push into the 350 range, which is solid moderate energy, but the swell’s still only 2 ft to 2 ft, and the wind is either onshore or cross-on. The waves just aren’t there. The morning of Saturday the 19th is flagged as marginal, with the wind light and onshore, but at 2 ft and 18 seconds—that’s a long-period swell that might wrap a bit, but there’s not enough size to make it worthwhile.
Sunday the 20th through to the end of the month doesn’t get any better. The combined energy climbs to 389 on Monday the 21st, and even 417 that afternoon, but with 3 ft swell and onshore or cross-on winds, it’s just messy. From Tuesday the 22nd onward, the energy drops back below 350, and the swell stays stuck between 2 ft and 3 ft. The last day, Sunday the 27th, has 3 ft from the southwest with 15-second period and cross-on wind—still poor.
So here’s the straight truth: this whole 16-day outlook has zero standout days. No clean waves, no glassy mornings, no proper size. The surf at Surfside Jetty is inconsistent at the best of times, and this stretch is a classic example of a long flat spell. If you’re a kite surfer, the cross-on and onshore winds with moderate energy might get you planing, but for paddle surfing? Leave it. Forecasts can change, but right now it’s a hard pass.

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