The Lowdown

Alright, Rusty here. Let’s have a look at what’s shaping up for L Jetty.

Honestly, I’ve got to be straight with you – the next 16 days are looking pretty flat and sad for L Jetty. There’s a big gap of no real surf at the start, and the few tiny bumps that show up later are barely worth a mention. The water’s sitting at 75°, which is a touch warmer than normal for this time of year, so at least the paddle’s nice if you’re just floating.

The first real chance to even talk about waves comes on Friday, August 28th morning. We’ve got a tiny 2ft swell from the SE, with a short period of 8 seconds and weak energy (90). The wind is light and offshore from the W, so it’ll be clean, but it’s just not enough to get excited about – surfable but very ordinary. That same little dribble of 2ft sticks around through Friday afternoon, still clean with offshore wind, but the energy is still just 96. It’s a wobbly, gutless wave.

Then we slide back into a real dry spell. From Saturday, August 29th right through to Monday, September 7th, each day shows poor surf conditions. The swell bumps up to 3ft on Monday, August 31st afternoon, but with a period of just 5 seconds, it’s all chop and no push. Even with offshore wind, that’s just a messy, close-out shorebreak. Not worth paddling out for.

The next time we see anything even close to a pulse is Tuesday, September 1st morning. Swell’s 2ft from the SSE, period 6 seconds, energy 66, with gentle offshore wind. Again, it’s surfable but very ordinary. That afternoon, the period jumps to 15 seconds – a very long groundswell – but the height is only 1.0ft. That’s just a long-period bump on a lake. For a beach/jetty setup like L Jetty, that long period tends to make the wave break too straight and fat, so it’s not going to offer anything fun.

From Wednesday, September 2nd through to the end of the forecast, it’s all onshore or cross-shore winds, mostly poor conditions, and the swell stays tiny – 1ft to 2ft. The combined energy never gets above 80, so it’s weak. There’s just nothing here that stands out.

The only highlight I can even point to is the Friday, August 28th window, but even that’s a stretch. It’s the closest we get to a clean, small wave. It’s not a standout – it’s just the best of a bad lot. For a beginner, this 2ft is fine, but it’s not going to be a memorable session.

Sorry, folks, but L Jetty is in a real slump. Blank runs like this are pretty normal for the area when the swell windows don’t line up. Forecasts can change, so keep an eye on it, but for now, I’d save the wax.

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.
