The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s on the cards for our stretch of coast.
To be straight with you, the next couple of weeks are looking pretty bleak. We’ve got a long stretch of small, weak waves and mostly poor conditions. The first real surf worth talking about doesn’t show up until the very end of the forecast, on Sunday, the 23rd of August. That’s a solid gap of nearly two weeks of flat or poor quality surf to get through.
The only standout in this whole 16-day window is the Sunday morning session at L Jetty. That’s the day to circle. We’re looking at a clean 6 ft swell from the south, with a period of 7 seconds. The combined energy of all swells directed here is up at 493 – that’s a strong, punchy amount of energy for this spot. The wind is light and cross-offshore, which should keep the surface clean. It’s a beach and jetty setup, so with that size and short period, it could get a bit lumpy, but it’s the best we’ve got. For the more experienced surfers, that’s your window. The water temperature is about average for this time of year, nothing unusual there.
Before that, there’s just nothing doing. The swell is tiny, mostly under 3 ft, and the period is short, often under 8 seconds. The winds are often cross-on or just messy. The energy readings are weak, usually in the double digits, barely reaching 100 in the second week. You’ll see a few afternoons with a bit of offshore wind, like on the 8th and 9th of August, but the swell is just too small to get excited about.
Late in the second week, around the 18th and 19th of August, the swell direction swings to the southeast and the period gets longer, up to 14 seconds, which is a proper groundswell. The energy jumps into the 150s and 190s, but the wind is either cross-shore or onshore, creating chop. The swell height is still only 2 ft to 2 ft, so even with that long period, it’s not going to produce much. That long period at a beach and jetty like L Jetty can also make it break too straight, so it’s not really a goer.
So, the short story is: wait for Sunday morning, the 23rd of August. That’s your one shot. The rest is a write-off.
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.
