The Lowdown
Alright, Rusty here. Let's have a look at what's on offer for the Jetty.
Well, I gotta be straight with you – this outlook is a real struggle. For the next two weeks, the Jetty is looking pretty flat and mostly blown out. We’ve got a long stretch of nothing much to get excited about.
From Sunday the 9th right through to Friday the 22nd of August, it’s a grim run of kneesnappers and onshore slop. The combined swell energy is weak, mostly under 100 (52 to 140), and the swell heights are tiny, rarely even hitting 3 feet. The wind is all over the shop, but mostly cross or onshore, keeping the surface messy. It’s not worth paddling out for.
Now, there is a glimmer of hope right at the end. On Saturday the 22nd of August, things finally line up. We’ve got a clean 3ft swell from the south, with a light offshore breeze in the morning swinging to a light cross-off in the afternoon. The combined energy is still modest (85 to 86), but it’s the cleanest we’ll see. This is the only day in the whole 16-day window that’s even surfable. It’s not a classic, but it’ll be the best on offer – a quiet, clean low-tide burger for those who’ve been watching the forecast all week.
The water temp is about average for the time of year, nothing unusual there.
Honestly, this is a blank run for the area. It’s a waiting game. The forecast can always change, but as it stands, mark your calendar for Saturday the 22nd if you’re desperate for a paddle.
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.
