The Lowdown
Alright folks, Rusty here. Gotta be straight with you – the outlook for L Jetty over the next 16 days is a tough one. We've got a real dry spell on our hands.
Looking at the whole picture, there’s a long gap here with very little to get excited about. The first eight days are a write-off. From Saturday the 5th right through to Wednesday the 16th of September, the surf is either too small or too messy to bother with. The combined wave energy is mostly weak, sitting between 12 and 75, with the odd bump up to 87. It’s just not happening.
The best we can hope for is a little window on Thursday the 17th of September. The morning shows a glimmer of hope with a small swell of 2 ft from the ESE, pushed by a clean, light offshore wind from the SW. The combined energy climbs to 73 (moderate energy) and the surf is described as surfable, though ordinary. It’s not going to be a classic, but if you’re desperate, that’s your moment. The period is a middling 9 seconds, so don't expect any groundswell power.
But even then, the afternoon at L Jetty on the 17th gets blown out by a strong 19 mph cross-shore wind, turning it lumpy. And after that, the following days through the 20th fade back into small, weak, and choppy conditions with energy dropping back into the 50s and 60s.
Honestly, there’s not a standout session in the bunch. For a spot that’s a fairly consistent beach and jetty setup, this is a real dry spell. Sometimes you just have to wait for things to pick up. It’s a flat spell, plain and simple.
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.
