The Lowdown
Alright, Rusty here. Let's have a look what's in store for L Jetty. I won't lie to you, it’s looking pretty grim for a long stretch.
We’re starting off right now and it’s a tough watch. Through the rest of August and into the very start of September, the swell is tiny to non-existent, mostly under 2ft, and on top of that, nearly every day has onshore or cross-shore winds messing things up. There’s a long gap here of nothing worth paddling out for. You’re looking at over a week of flat, choppy, or just plain poor conditions. The surf is there in name only, but it’s not really surfable.
We finally see a flicker of life around Thursday the 27th of August in the afternoon. The swell bumps up to 4ft from the S, and the wind goes glassy. That’s the one real standout of the entire forecast. The combined energy is moderate (248), so there’s some push behind it. This could be a decent session for an intermediate surfer, but with that size being under 5ft, it's accessible. It’s also a long way out, so keep an eye on it.
The Friday and Saturday after that see a bigger swell pushing in – up to 7ft from the E on the 28th, and 5ft on the 29th – but unfortunately, those days are riddled with onshore winds. That’s going to make a mess of it, turning any size into chop. That bigger energy (342 and 442) will be there, but it’s not going to be pretty. For a beach/jetty setup like this, with that kind of wind, it might look more interesting for kite surfing than paddle surfing. After that, it drops back down into the small stuff again.
So, to be honest, there’s not much to get excited about. If you’re desperate, keep an eye on that Thursday afternoon the 27th, but otherwise, the first half of this outlook is a write-off.

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.
