The Lowdown
Alright, let’s get into it.
Honestly, for the next two weeks, you're gonna be looking at a whole lot of flat, grovelly junk. We’ve got a pretty long stretch of nothing doing at L-Jetty. The first surfable waves show up on Friday the 28th in the morning, but it’s small, soft, and nothing to write home about. That clears out fast too, and then we’re staring at a dead zone for a good four or five days.
The first real glimmer of something with a bit of push shows up on Thursday the 3rd of September. It’s a clean morning, with a light offshore wind out of the west, and we finally see some energy in the water. The swell jumps up to 5ft from the east-northeast, with a short-period windswell (6 seconds). The energy reading is moderate at 175, which is the biggest number we’ve seen. It’s still not perfect – a bit short-period – but with that offshore wind, it’ll be clean and head-high. That’s your first real window to get out. The afternoon stays clean too, with a cross-offshore breeze, but it drops slightly to 4ft.
That’s followed by a bit of a letdown. Friday the 4th sees a decent 3ft of east swell but with a moderate cross-shore breeze that’s gonna chop it up. Not great. Saturday the 5th is worse, with onshore winds and lumpy conditions. We get a few other days of small, messy surf from behind, but nothing that’s really gonna get your heart racing.
The final day on the list, Friday the 11th of September, has a bit of potential as a dark horse. It’s a clean morning, light cross-offshore wind, and we’ve got 3ft of south swell again. It’s not big, but with the clean conditions, it’ll be a fun, uncrowded session for someone on a log or a fish.
Honestly, the standout of the entire run is that Thursday the 3rd. It’s the biggest, cleanest, and has the most energy. Everything else is marginal. The water temp is 74°, which is about average for the time of year, so just a normal summer wetsuit.
It’s a long, quiet spell out there boys. Be patient.

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.
