The Lowdown
Alright, this is Rusty. Let me tell ya, it’s been a rough stretch out here. We’ve got a 16-day window, but honestly, this one’s a bit of a heartbreaker. The first real chance of anything resembling a wave doesn’t show up until Friday the 28th of August, and even then, it’s not much to write home about. Before that, we’re looking at a solid week of flat, choppy, or just plain ugly conditions. From the 21st through the 27th, it’s a write-off – minimal swell, mixed-up winds, and a whole lot of nothing. You’d be better off waxing your board and just staring at it.
Now, the best we’ve got in this whole gloomy outlook is a brief window on the afternoon of Friday, the 28th of August, at L Jetty. The combined wave energy jumps to a moderate 334, which is the only time we see real push. We’re looking at a SSE swell pushing through at about 4ft, with a period of 8 seconds – that’s a bit of a junky windswell, but it has some oomph. What makes this the standout is the wind. We’re getting a clean, cross-offshore breeze out of the Southwest, which should tidy things up nicely. The surf will be in the waist-to-chest high range, and with those offshore conditions, L Jetty might just have a few fun ones peeling down the wall. But keep your head on a swivel; the crowds are "often" here, so expect some company.
After that little pulse, it backslides. The 29th and 30th see the swell drop right back down to knee-high dribble. By the 31st and into the final two weeks, it’s more of the same – tiny surf, onshore slop, or just dead flat. There’s a couple of glassy mornings on the 2nd and 3rd of September, but with swell under 1ft, there’s nothing to ride. The water temperature is sitting at a very unusual 78°F – that’s more than 5°F warmer than average for this time of year, so you can leave the fullsuit at home if you’re just going for a swim.
In short, there’s one day in a fortnight that might just deliver a couple of decent waves. The rest is a survival mission. Hang in there, and check back closer to the 28th.
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.
