The Lowdown
Alright, Rusty here again. The outlook’s been quiet for the first few days, so let’s break down what we’ve got in feet and miles per hour.
Our spot is L Jetty. It’s a beach and jetty setup, exposed to the swell, with the best swell coming from the ESE. Water temp is normal for this time of year.
The first real chance comes on Saturday the 29th of August, early. A weak 2ft swell from the ESE, 8-second period, and a light SW cross-off wind at 6 mph. The surface will be clean. Wave energy is low at (63). It’s ridable but nothing to write home about. Afternoon gets choppy, so the morning is the window.
Next up is a week later on Wednesday the 2nd of September. Morning brings a clean 2ft swell from the ESE, 12-second period, and a WNW offshore breeze at 6 mph. Energy hits moderate at (145). Again, it’s just ordinary.
The standout in the whole 16 days is Thursday the 3rd of September afternoon. Swell picks up to 4ft from the ESE, 10-second period, with a solid cross-off wind from the NNW at 16 mph. Combined energy jumps to a strong (296)—the best of the run. It’s labeled marginal tide-wise, but this is the one to watch. It’s a long way out, so keep your fingers crossed.
Friday the 4th of September has 3ft from the E both morning and afternoon, but the period is a short 5 seconds, so it’ll be weak and gutless. Wind stays clean cross-off though.
From the 5th onward, the wind turns against us and the chop kills it. Nothing else worth a mention.
So the takeaway: the morning of Saturday the 29th, the morning of Wednesday the 2nd, and the real standout is the afternoon of Thursday the 3rd of September. For everything else, you’re better off waxing your board and waiting.
Stay tuned, forecast can flip.
Rusty.

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