The Lowdown
Alright, Rusty here, checking the numbers for L Jetty. It’s a lean month ahead, I’m not gonna sugarcoat it. We’re looking at a 16-day window, but the first week and a half is a real barren stretch.
The water is reading 75°F, which is much warmer than normal for this time of year, so you can at least be comfortable while you’re waiting for something to show up.
We start off on Tuesday, the 8th of September, with some tiny 0.7ft swell out of the ESE, but a 12 mph south wind is making it a cross-shore mess. The energy is weak (14), and it’s just poor surf. That’s your theme for days. There’s a little spike of 3ft S swell on the morning of Thursday the 10th, with a clean offshore wind from the WSW, but the swell period is a short 6 seconds, so it’s gutless. The wave energy is weak (62). It’s surfable if you’re desperate, but it’s very ordinary.
We then have a long, dry gap of poor conditions. A few clean offshore moments on the 16th, but the swell is barely there. The 17th sees a 0.7ft swell with a 13-second period, which is that long-period groundswell, but it’s just too tiny to work and the wind is onshore.
The only real pulse of energy, and I mean the *only* one, comes on the 20th and 21st of September. On Sunday the 20th, the morning is a jumbled 4ft from the ENE (75 energy), but it’s cross-shore. The afternoon shows a 6ft east swell, and the energy jumps to 334 – moderate energy. Monday the 21st brings the biggest numbers: a 7ft east swell with a period of 8 seconds, and the energy is a solid 537. That’s a strong pulse of windswell.
But for L Jetty, a beach/jetty, that swell is coming straight onshore from the east. For a 7ft swell, that’s expert territory and it’s going to be a choppy, blown-out mess. The quality is still rated as poor or marginal. Honestly, with that much swell and onshore wind, you’d be better off rigging a kite than trying to paddle. It’s just not the clean, lined-up wave we’re after.
So, bottom line for L Jetty: there are no standouts. The best wave energy is far too messy to be a genuine recommendation. It’s a tough outlook.
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.
