The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for L Jetty over the next couple of weeks.
First off, I gotta be straight with you – the 16-day outlook is a tough one for L Jetty. We're looking at a long, dry spell of poor surf kicking off now and running right through until the start of the third week. The water temp is sitting right around average for this time of year, so nothing weird going on there.
For the first week, from Monday the 7th right through to Sunday the 13th, it's a total bust. We're talking tiny, weak waves, mostly under 2 ft, with combined swell energy barely cracking 50. The wind is all over the place, but the swell just isn't there. You'd be better off waxing the kiteboard than the paddleboard through this stretch.
The second week isn't much better. Monday the 14th through to Sunday the 20th is more of the same – small, weak, and unappealing. The swell does try to pick up a bit on the 14th with a 4 ft southwest swell, but it's a short-period 5-second windswell with 19 mph winds, which just makes for a messy, blown-out afternoon. Not worth the drive.
Now, here's the one glimmer of hope, and it's a long way off. Mark your calendar for Monday the 21st of September. The morning brings a glassy, flat calm with a 5 ft north-easterly swell. The combined energy jumps to a moderate 120, and the 5-second period is short, but the glassy conditions will make it look clean. This is a beginner-friendly size. Then, Tuesday the 22nd of September morning is the real standout of the whole forecast. We've got glassy conditions again, a 6 ft easterly swell pushing combined energy to 233, and a 6-second period. It's big enough to be fun but still manageable for a lot of crew. The conditions are clean and glassy. This is the session to aim for if you can wait that long. It's a long-range call, so keep an eye on it, but as it stands, that Tuesday morning is the best we've got.
So, to sum it up: a whole lot of nothing for two weeks, then a decent little window right at the 16-day mark. Don't hold your breath, but don't write it off completely.
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.
