The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the local stretch.
It's a quiet outlook for the next 16 days, I won't lie. There’s a real gap at the start of the period with no real surf on offer. The first few days are pretty much a write-off, with tiny, weak waves and poor conditions. It’s not until Thursday the 3rd that we see anything worth paddling out for, but even then, it's marginal.
For the first real chance, we’re looking at Thursday morning, September 3rd at L Jetty. The swell is a small 3ft out of the ESE, and the combined energy is weak (92). The water is a touch warmer than normal for this time of year at 75°. The wind is a light cross-off from the SW, which is keeping things clean, so the waves will be surfable. It's nothing to write home about, but it's the best we've got early on. The afternoon gets even better with a glassy window, but it's a bit smaller at 2ft, though the energy bumps up a notch (125). Keep in mind, this spot can get crowded, so you might have some company.
After that, we hit a dry spell. From Friday the 4th right through to about Wednesday the 9th, the swell drops right off. We're talking knee-high dribble at best, with poor conditions dominating. It's a long stretch of flatness.
There's a slight pulse of energy on Thursday morning, September 10th, with a 3ft south swell, but it's short-period and the wind is a stiff moderate breeze. The conditions are clean, but it's a bit of a messy, weak wave. The afternoon is an improvement with a clean offshore wind, but the size drops to 2ft.
The pattern continues with very small, weak swell for the rest of the period. The second week is a write-off, with nothing but tiny, underpowered waves and strong winds. There is a sniff of a longer-period groundswell (13 seconds) appearing on the 17th and 18th of September, but the swell height is only 0.7ft to 1.0ft, so it's completely flat. There's just no energy for it to work with.
Honestly, Thursday morning, September 3rd, is your standout. Get on it early before the crowds show up, because the rest of the window is a desert. The waves are small and the energy is low, but with that glassy afternoon session on the 3rd, you might just snag a few fun ones.
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.
