The Lowdown
Alright folks, let's talk L Jetty. It's a long stretch of smallness here, but there’s a little payoff waiting for you if you can hang in there.
Starting now, the surf is just plain weak. The swell is tiny, mostly under 2 feet and often down around 0.7 feet to 2 feet, and the energy is low, usually in the 20s, 30s, or 40s (combined energy). The wind is often coming cross-on or onshore, making it a messy affair. The water is sitting at a balmy 78°, which is a massive 6° warmer than what we usually have this time of year. That’s incredibly warm.
There are a few clean moments. Sunday the 24th and Monday the 25th of August give you some offshore flow out of the west. The waves are still tiny, but it'll be clean. Tuesday the 26th of August morning is glassy calm, dead flat, but you can’t surf flat water. Even when the swell bumps up to around 3 feet or so on the 30th and 31st, the wind messes it up, bringing a nasty cross-chop.
The one to watch is Tuesday the 1st of September. The afternoon brings a solid groundswell from the east-southeast at 4 feet with a long 14-second period. The wave energy spikes to 643, which is a very strong pulse. The wind goes light cross-offshore, keeping the surface clean. That’s the standout. This size and power are for experts only; it’s too big for beginners.
Wednesday the 2nd still has some leftover clean 2-foot swell with a 12-second period in the morning, but the big moment is that Tuesday afternoon.
The rest of the run into September fades back into small, choppy nothingness. It’s a long dry spell, over a week of surfing nothing, but that first day of September looks worth the wait. Crowds shouldn't be an issue most of the time, but that Tuesday might bring a few out of the woodwork.
Keep the wax warm. 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.
