The Lowdown
Righto, grab a coffee, 'cause we've got a long, quiet spell ahead here at L Jetty. This is Rusty, and I've gotta be straight with you – the next two weeks are looking pretty flat and uninspiring. There's a big gap of no good surf for days on end, so don't be holding your breath.
We start off with nothing doing right from the get-go. From Sunday the 6th right through to the morning of Tuesday the 10th of September, it's all poor surf conditions with tiny, weak swell. The water's unusually warm though, sitting at 75°F, which is much warmer than normal for this time of year – a weird little anomaly to go with the flat spell.
Finally, on Thursday the 10th of September, we get a little blip of life. The morning sees a 3ft southerly swell with a short period of 6 seconds, and combined energy is weak at 85. By the afternoon, it bumps up to 4ft from the south, period still 6 seconds, and energy gets into the moderate bracket at 118. It's not much, but here's the thing: the wind goes offshore from the WSW at 12 mph both sessions. That offshore wind will clean things right up. It's not going to be epic, but for a break that's been dead, a clean 4ft wave with offshore wind is about the best we've got on offer. This is the one true standout in the whole outlook – surfable waves, clean conditions, and you'll likely have it to yourself.
After that brief highlight, it's right back to the doldrums. From Thursday afternoon right through to the end of the outlook on Monday the 21st of September, the forecast is a string of poor surf conditions. There are a few moments with clean conditions, like Wednesday the 9th and Tuesday the 15th, but the swell is barely a ripple – 0.7ft or 1.0ft. It's simply not worth paddling out. We see a bump in swell on the 17th of September with a 4ft east-northeasterly swell, but it's cross-on shore, choppy, and the period is a short 6 seconds. The energy is moderate at 146, but with that wind, it's going to be a mess. Honestly, for the kite crew, the wind on the 16th is strong and cross-onshore, so that might be more interesting for them than us.
So, to sum it up: we've got one decent, clean window on Thursday the 10th of September. The rest is a long, flat run. It's a quiet period for L Jetty, but forecasts can change. Keep an eye on it.
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.
