The Lowdown
Alright folks, Rusty here. Let's talk about what's on the table for L Jetty over the next couple of weeks.
First thing you need to know: the water's sitting at about 74°F right now, which is a solid 5°F warmer than usual for this time of year. That's a noticeable difference, so you might get away with a thinner wetsuit or even a shorty if you're brave.
Right, let's get into the surf. The truth is, the next week and a half is a tough stretch. There's a long gap with hardly anything worth paddling out for from now through to around the 23rd of September. You'll see tiny, weak waves with low energy readings (50 or less most days) and a lot of messy wind. There's a tiny pulse on Sunday the 13th with a 2ft SE swell and glassy conditions – that's a rare clean window, but the energy is weak (50) and the waves are small. It's surfable but it's not going to get the heart pumping. After that, Monday the 14th through to the 23rd is pretty much a write-off with poor conditions and onshore or cross-off breezes. The 21st and 22nd see a bit more size, with 5ft to 5ft of ENE swell, but the wind is either howling onshore or choppy, so it's a messy affair. Combined energy jumps up (254, 223) but the quality just isn't there for a good paddle session.
Now, hold on to your board, because things finally turn around on Thursday the 24th of September. That morning we get a nice 6ft ENE groundswell with a clean 8-second period, and the wind swings offshore from the west at a gentle 9 mph. The energy reading jumps to a solid 470 (moderate wave energy), and the conditions look clean. This is the standout. For a beach and jetty setup, that offshore wind will make all the difference, and the swell is at that sweet spot where it's got some punch but isn't too crazy. It's not going to be tiny, but it's not massive either – a good all-round size for intermediates and above.
The morning of Friday the 25th is also worth a mention. Offshore wind again, this time from the WNW, with a 4ft E swell and a period of 9 seconds. The energy is still solid at 203. It's not the same size as Thursday, but it'll be clean and offer some fun lines.
So, if you're looking for the best on offer, make a plan for the morning of Thursday the 24th. Friday the 25th is the backup. Everything before that is a waiting game. L Jetty can be inconsistent, and this stretch proves it, but that Thursday window looks promising. Just remember, long-range calls like that are promising but less certain.
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.
