The Lowdown
Alright, Rusty here. Let’s take a look at what’s coming down the line for L Jetty.
First thing you need to know – this is not a run of great surf. We’ve got a long stretch of flat, poor, or small, choppy junk to wade through. The whole 16-day window is pretty lean, but there are a couple of rare, half-decent windows if you’re keen and not too fussy.
The upcoming week is a write-off for the most part. From early Tuesday the 8th right through to Monday the 14th, it’s poor conditions across the board. Tiny little 0.7-2 ft slop, mixed with onshore breezes or cross-shore junk. Combined wave energy is barely registering. Not worth paddling out for.
Thursday morning the 10th shows a small pulse of 3 ft S swell with a short 6s period, but the wind is offshore and the combined energy is still weak. It's surfable, but very ordinary. Only worth it if you're desperate for a paddle.
The first real standout, and it’s not a big one, arrives around Wednesday the 16th. A 4 ft ENE swell pushes through in the morning, with clean, cross-off winds from the NNW. Combined energy jumps to 113. It’s small but clean, with moderate energy. That morning is the pick for the first half of the window.
Then we get a dry spell again until late in the period. Sunday the 20th afternoon brings a 3 ft S swell with offshore W winds, giving clean conditions. Then Monday the 21st morning is even better for the window: 2 ft S swell, glassy conditions (light offshore W at 3 mph), clean surf. That Monday morning is likely the best on offer for the whole 16 days.
Outside of that, there's not much. The rest is either onshore mush, tiny windswell, or no swell at all. L Jetty is a beach and jetty setup, so when the swell is these short-period, weak pulses, it's not going to fire. Could be more interesting for a kite surfer on those windier days.
The water temperature here is about average for the time of year. Not a warm anomaly, not a cold one.
To wrap it up: the whole run is mostly poor, with Monday the 21st morning as the standout. Aim for that if you can.
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.
