The Lowdown
Alright folks, Rusty here. Let's have a look at what L Jetty has got cookin' for us over the next couple of weeks.
Honestly, it's a pretty flat start, so don't bother waxing up just yet. We're looking at a solid 6-day stretch of tiny, weak surf with no real quality on the cards. From Monday the 14th through to Saturday the 19th, we're stuck with ankle-snappers mostly under 2 ft. The combined energy is pitiful, barely cracking 50 on the best day, and that's being generous. Winds are a mixed bag, mostly cross or cross-on, so nothing to get excited about. Just a whole lot of nothing.
Sunday the 20th stays small at 1 ft, but there's a little glimmer: a clean, moderate offshore breeze from the west in the morning. It'll be glassy but tiny. The best part of this whole stretch is Monday the 21st. We get a sudden spike in size, with the swell jumping to 7 ft from the ENE. That's a big, raw, onshore mess though, with a combined energy of 474 (moderate). The wind is straight on it, and it's a beach/jetty setup, so it's gonna be a washing machine. Honestly, that looks way more interesting for the kite crew than for a paddle surfer.
Now, hold onto your boardshorts. Wednesday the 23rd is the real standout. The swell holds at 8 ft from the east, and the period is a solid 8 seconds. The combined energy jumps to a powerful 1055 (strong). But the kicker is the wind: a clean, cross-off breeze from the NNW. That's the ticket. This is going to be proper, clean, head-high-plus surf for experienced surfers only. If you've got the skill, this is your window. It will be too big for beginners.
The days after that drop off quick. Thursday the 24th stays big at 8-8 ft from the east, but the wind swings back cross-on, making it choppy and marginal. By the following Saturday, the 26th of September, the swell settles to a much friendlier 4 ft from the east, with a nice 11-second period (long period groundswell). And the wind? Dead calm, glassy conditions all day. That’s a beautiful, clean, intermediate-friendly session, but watch for longer waits between sets. By Sunday the 27th it's cleaning up again but dropping fast, and by the 29th we're back to tiny dribble.
So to sum it up: endure the first week of nothing, then get ready for a solid, expert-level day on Wednesday the 23rd, followed by a glassy, fun-sized morning on Saturday the 26th. The rest is a write-off.
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.
