The Lowdown
Right, let’s have a look at what’s cookin’ for L Jetty over the next couple of weeks. First things first, I gotta be straight with you – the surf outlook for the next 16 days is pretty grim. There’s a long stretch of nothing much to get excited about, and I mean a real flat spell.
We start off on Sunday, 23rd August, and honestly, it’s a dud. The swell is tiny, just 1ft from the ESE, and the wind is a messy cross-off. The water’s a touch warmer than normal at 76° – about 3° above the average for this time of year, so that’s a bit of a novelty, but it won’t help the waves. The energy is weak (19), and conditions are just poor. This sorry state of affairs runs right through the week. Monday 24th, Tuesday 25th, Wednesday 26th – it’s the same story: small swell, poor quality, and the best you’ll see is a bit of glass on Wednesday morning with 1ft and a glassy wind from the NNE, but it’s still not worth paddling out for.
Thursday 27th and Friday 28th are still flat. Friday morning does have a glassy surface with the wind dying to nothing, and the swell bumps up to 1ft, but the energy is still weak (65) and the wave comment says it’s “surfable but very ordinary.” That’s not a recommendation from me, mate. Saturday 29th and Sunday 30th are just as bad, with onshore winds and tiny swell.
Then we hit a bit of a strange period. From Monday 31st August into early September, the swell period starts to get long – we’re talking 17 to 18 seconds, which is proper groundswell. But the height is still tiny, only 0.7ft to 1ft, so it’s all show and no go. The energy ticks up a bit on the 1st of September, hitting 143 (moderate), with 2ft from the ESE, but the wind is onshore and messy. Not a session.
The only two days that even raise an eyebrow are Thursday 3rd and Friday 4th September. On Thursday morning, we get 2ft from the ESE with a 10-second period, and the wind is offshore from the WSW, keeping things clean. The energy is still low (86), but it’s surfable. Friday morning is similar, with 1ft and gentle offshore wind. These are the only times in the whole 16 days where the conditions are described as “surfable” – but honestly, it’s marginal at best.
The standout? Well, if I had to pick one, it’s Saturday 5th September. The swell jumps to 3ft from the SE, with a 13-second period and a clean cross-off wind from the NNW. The energy is strong (266), and the afternoon session is actually rated as “expect good surf conditions.” That’s the best on offer, but it’s over a week away, so keep your fingers crossed. For a beach/jetty setup like L Jetty, a long-period swell can sometimes break a bit straight, but with that offshore wind, it should hold up okay.
Overall, it’s a bleak run. If you’re desperate, the 5th of September is your best bet, but don’t get your hopes up for much else.

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.
