The Lowdown
Howdy, Rusty here. Let’s break down what L Jetty’s got lined up.
Truth is, the first week or more is a real struggle. From Wednesday the 16th through to the middle of the next week, the wave energy’s barely there – most days the combined energy sits under 100 (19 to 97), which is real weak. We’re looking at tiny 0.7ft to 1ft waves with short periods, and even when it’s clean, there’s nothing to ride. You’d be better off checking the tide pools.
The first glimmer of hope hits on Thursday the 24th of September, early in the morning. The wind goes glassy – just 3 mph from the SW – and the swell ticks up to 3ft from the east with an 8-second period. Combined energy hits 121 (moderate). It’s not epic, but it’s surfable and clean. L Jetty is a beach-and-jetty setup, exposed to the ESE swell, and it’s fairly consistent here, though you’ll often find a few others out. Water temp is 74°, which is 5° warmer than average – that’s very unusual for this time of year, so a spring suit is plenty.
Now the real standout, and it’s over a week out so keep the fingers crossed, is Wednesday afternoon the 30th of September. The swell jumps to 6ft from the east, period 6 seconds, with combined energy of 310 (moderate). Wind is a gentle 9 mph from the NNW, cross-offshore, keeping the faces tidy. For L Jetty, that’s the best deal in the whole run – clean waves with enough size to get a few proper turns in. The short period means it’ll be a bit fat, but on the jetty it should line up alright.
After that, Thursday the 1st of October brings a monster – 13ft from the ENE with energy over 3900 – but that’s way too big for this spot, and with onshore wind it’s a total mess. Only for the madmen.
So bottom line: a long flat spell, a small clean session on the morning of the 24th, and a proper standout afternoon on the 30th of September with 6ft waves and offshore wind. The rest is a skip.
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.
