The Lowdown
Hey folks, Rusty here. Look, I’ve gotta be straight with you – the next 16 days at L Jetty are a real struggle. The finder isn’t giving us a single recommendation, and looking at the guidance, it’s a tough stretch. The break is a beach/jetty setup, exposed to the ESE, and it’s fairly consistent but with an intermediate rating. The water temp is sitting at 75°F with a 4°F anomaly, which is much warmer than normal for this time of year – feels like a late summer holdover, but that’s about the only upside.
We’re looking at a blank run for the entire period. From Friday, September 4th, right through to Saturday, September 19th, every single session is marked as poor surf conditions. The swell heights are tiny, mostly 0.7ft to 3ft, with periods all over the place – some short, weak 4-second windswell, and a few longer 10-13 second pulses that never get any size. The combined energy is weak, ranging from 9 to 70 (just a whisper of energy). The wind is often cross-off, which is clean, but with almost no swell to work with, it doesn’t matter. There’s a morning on Tuesday, September 8th, with a clean offshore from the WNW and a 1.0ft, 10-second swell, but it’s just not enough to break. The same goes for the morning of Monday, September 14th, with a clean offshore from the W – same story, tiny 0.7ft wave.
The biggest issue is that the swell direction is often from the E or ENE, but the optimum direction for L Jetty is ESE, so it’s rarely hitting the spot right. The crowds are often here, so even if there was a wave, you’d be sharing it. Honestly, for a beach/jetty, this setup is more interesting for kite surfing than paddle surfing – the wind is consistent enough on some days, but the waves just aren’t. Sometimes a stretch like this is normal for the area, so don’t lose hope – forecasts can change. But right now, I’d leave the board at home.

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.
