The Lowdown
Alright, folks, let’s be real. I’ve been staring at this one and it’s a tough stretch. We’ve got a couple of weeks of small, weak surf ahead. The waves just aren't showing up.
The first week, from Thursday the 27th through the 3rd, is a total write-off. Swell stays under 3 feet for the most part, and the energy in the water is weak, with numbers in the 20s and 30s. It’s just tiny, messy slop with a cross-shore wind making it lumpy. Saturday morning the 29th cleans up a touch with a NE breeze, but it’s still only 2ft – not worth the paddle out unless you’re just after a splash. We get a bit of energy on Friday the 28th (106), but it doesn't translate to any decent shape.
From the 30th through to the 3rd, it's a real flat spell. The energy numbers drop into the 20s and 30s, it’s dead quiet.
The second week finally shows a pulse, but it’s not one to get excited about. On Saturday the 5th of September, the afternoon swell jumps up to 5ft from the East, but a 15 mph cross-shore wind chops it all up. The energy is moderate (238), but it's short-period windswell, so it'll be lumpy and lack any punch. This one looks more fun for the kite-surfers than us paddlers.
Sunday the 6th has a bit more energy (139) with a 2-3ft swell, but again, the wind is all over it. After that, it just fades back into the tiny dribble we've been seeing. There is no standout period, no glory window. The only time it looks clean, like on Friday the 11th with a cross-off breeze, the swell is barely 1-2ft.
It's a frustrating run. The water temp at Jetty is 72°, which is about average for the time of year, so a swim is comfortable, but that's about all you'll be doing. This is one of those blank stretches that happens. It won't stay this way forever, but this forecast is a long one to stomach.

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.
