The Lowdown
Alright everyone, Rusty here. Let’s be real with you. The next two weeks are looking pretty average, with a whole lot of nothing on the cards. We've got a long stretch of small, weak surf ahead, so don't get your hopes up.
The first real chance of a surf doesn’t show up until the 1st of September. That’s more than a week of waiting through tiny, messy waves. Test your patience, it will.
The standout window, for what it's worth, is the 1st of September. That Tuesday morning we finally see a bit of energy (125), with a clean cross-offshore wind, but the swell is still small at 3ft. The afternoon shapes up a bit better with a proper offshore wind and a bit more push (148), making it the best of the whole run. Still, it's just "ordinary" surf. The following Wednesday, the 2nd, has a touch more size and period, but the wind goes cross-shore and chops it up.
Before that, the 31st of August has a burst of energy (107) but a fresh cross-shore wind ruins any chance of it being clean. And the 27th through the 29th are just clean but too small to get excited about.
We'll be at L-Jetty. The water is running a touch warmer than usual for this time of year, so on the 20th you might not need the thickest wetsuit, but that's about the only positive. The wind is mostly onshore or cross-onshore, and when it's not, the swell is tiny. The swell direction is mostly from the SE or ESE, and the break is exposed to it, but it's just not working.
There are a few days with a short period swell of 5 seconds, which is just wind chop and won't offer any real shape. It's all closeouts and weak. There's a day, the 26th of August, where the onshore wind and short period swell just makes it a total mess. Honestly, if you're into kite surfing, the 3rd of September with that strong onshore wind and lumpy 2ft might be your thing, but for paddle surfing, it's a no-go.
So, if you can wait, the 1st of September is your only real shot. It's not big, it's not perfect, but it's the cleanest and most energetic we're going to see. It's promising, but don't get too excited. The rest is a waiting game. These long-range calls are less certain, so keep an eye on the forecast, but right now, this is what we've got.
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.
