The Lowdown

Alright folks, Rusty here. Let's have a look at what L Jetty's got cookin' for us over the next couple of weeks. I'm gonna be straight with you – it's a tough outlook for the paddle crew. We're looking at a long stretch of small, weak, and messy conditions before we see a little pulse of energy later on.

First up, the water temp is about average for the time of year, so no surprises there. For the first week, right through to the 7th of August, it’s pretty grim. The swell is tiny, barely scraping 3 ft, with a short, weak period. The combined energy is pathetic, sitting in the double digits (66) most days, with a few bumps into the 80s. On top of that, the wind is mostly a messy cross-shore or cross-on, making it choppy and lumpy. Honestly, for a beach/jetty setup, this looks more like a kitesurfer's playground than a surfer's. The only real glimmer in this first week is Monday morning, the 3rd of August, when a light WNW offshore breeze cleans things up, but the swell is still tiny at 2 ft from the SSE with a period of 8 seconds – it's a nice clean ripple, but not much more.

Then we hit a bit of a dry spell. Tuesday through Friday (the 5th to the 8th) is a total write-off with tiny, weak swell and poor winds.

Now, hold onto your boards, because things finally get interesting on Saturday, the 8th of August. The morning window shows a pulse of better energy. We're looking at 3 ft swell from the SE, but the period jumps to 11 seconds, and the combined energy rockets up to 190 (moderate wave energy). The best part? A light offshore wind from the west. That's a clean, lined-up set-up that could actually give you a few fun ones. The afternoon gets a bit cross-shore, so I'd be on it first thing. This is likely the standout of the entire forecast.

The next day, Sunday the 9th of August, the swell builds further. The morning sees 4 ft of SE swell with a 12-second period, and the energy is a solid 408 (moderate to strong). The wind is a gentle cross-shore, so it'll be a bit lumpy but the waves will have some push. The afternoon turns onshore, so again, the morning is your window. This is a promising but less certain call since it's a week out, but it's the best we've got.

After that, from the 10th through the 14th, the swell stays around 3 ft to 5 ft from the SE/E with a solid 11-12 second period, and the energy is strong (up to 590). But the wind is a killer. It's onshore or cross-onshore, making conditions poor. It's a real shame because there's energy in the water, but it's going to be blown out and choppy. This stretch is only for the dedicated, and probably more suited to the foil or kite crew.

So, to wrap it up: the first week is a wash. The best bet is the morning of Saturday the 8th of August for a clean, fun session, and then the morning of Sunday the 9th of August for a bit more size, though slightly lumpier. Keep your eyes on the wind, and don't get your hopes up for the rest of 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.
