The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for L Jetty over the next couple of weeks.
Right off the bat, I gotta be straight with you: this isn’t a stretch of days that’s gonna have you paddling out with a big grin. The whole 16-day window is a lean run, with only a single session that even scrapes into being surfable, and even then it’s pretty ordinary. We’re looking at a long stretch of days with no real recommendations, so if you’re hangin’ for a wave, you might be better off just keepin’ the board in the car.
The water temp at L Jetty is a balmy 78°, which is much warmer than normal for this time of year – that’s over 4 degrees above average, so it's a real treat if you’re in the water.
The first good mention isn’t until Saturday, 22nd August. The morning still looks poor, but the afternoon session on the 22nd finally shows something. We’ve got a tiny swell from the S at 2 ft with a period of just 6 seconds, and the wind is light from the S, keepin’ it clean. The combined energy of all swells is a weak 52, so there’s barely any push. The comment says "surfable waves but very ordinary conditions," and I’d have to agree – it’s ankle to knee-high dribble, best for a longboard or a float.
After that, it’s right back to the poor stuff. The rest of the window from the 23rd of August through to the 26th of August is all flat, small, and messy, with cross-on winds and onshore junk. No standouts, no hidden gems. It’s a drought.
So, if you’re desperate, that Saturday afternoon on the 22nd is the only window. Otherwise, this is a good time to wax the sticks, check the ding repair, and wait for a better forecast. The setup looks more interesting for a kite surfer on a windy day than a paddle surfer any time in this period.
Stay patient.
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.
