The Lowdown
Alright, Rusty here again, looking at the same stretch of water.
Let’s call it like it is: the next 16 days are a dud for Jetty. We start with a long dry spell, and the few times the ocean even bothers to show a pulse, it’s barely a heartbeat.
The first chance you’ve got to get wet is Saturday, August 29, in the morning. There’s a 2-foot swell out of the southeast with a short 8-second period. The energy is weak. The saving grace is a light cross-offshore breeze from the north-northeast at 6 mph, keeping it clean. It’s surfable, but real ordinary. And with crowds possible, you won’t be alone.
Then the ocean goes dead for days. Nothing but poor conditions. Next up is Monday, September 7, in the morning. We get a 2-foot swell from the east-southeast with a longer 11-second period, giving it a bit more push, with moderate energy for this spot. The wind is a gentle offshore from the north-northwest at 9 mph, so the surface is clean. Still, just ordinary, tiny surf.
After another quiet stretch, Thursday, September 10, in the afternoon offers one last chance. A 2-foot swell out of the south-southeast, a 10-second period, and a light offshore wind from the north-northwest at 6 mph. It’s clean, and the energy is moderate, but it’s still small and uninspiring.
To put it bluntly, this is a tough forecast. The swell is tiny and weak, and the few clean windows don’t have any punch. For a paddle surfer, it’s looking like a lot of time on the beach. For a kite surfer, those onshore and cross-shore days with a clean-ish surface might be more interesting, but for a surfboard, it’s a hard pass right now. Things can change, but for the moment, it’s a blank run.
Rusty, out.

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.
