The Lowdown
Alright, let’s take a look.
To be straight with you, this outlook for L Jetty is a real quiet one. There’s barely a ripple worth getting excited about for the next 16 days. The whole period is pretty flat and messy, so if you’re desperate for a paddle, you’ll be scratching for anything.
Right now, through the end of August, it’s all small, weak swell with poor conditions. Tuesday the 18th and Wednesday the 19th have tiny 2 ft SE swell, but the wind is on it or cross-on, so it’s choppy and weak. The combined wave energy is only around 32 (weak). Thursday the 20th is even smaller, 1 ft, with a bit of cross-off wind but still not worth the drive. Saturday the 22nd sees a bump up to 4 ft to 4 ft E swell, but the period is a short 5 to 6 seconds and the wind is onshore at 16 mph, so it’ll be a bumpy, jumbled mess. Energy climbs a bit to 106 (moderate) but the quality just isn’t there.
We get a bit of relief late on Sunday the 23rd with a brief window of offshore wind (WSW 9 mph) and a 2 ft E swell, but it’s only a short window, and the swell is tiny. The energy is only 45 (weak). Monday the 24th morning is the only real stand-out in this whole stretch. You’ve got a 2 ft SSE swell with a clean offshore wind (W 12 mph), and the combined energy is 54 (still weak). The report tags it as surfable but very ordinary. It’s not going to blow your mind, but for a small wave log or foamy, it might be the cleanest you’ll get if you’re really keen. Crowds are possible here so don’t expect solitude.
After that, it fades back to tiny, choppy junk through the rest of the month and into early September. A few pulses of long-period swell show up around the 26th to the 30th with periods up to 16 seconds and energy jumping into the 100s and even 390 (strong) on the 30th, but the wind is always cross-on or onshore, so the waves will be messy. On the 31st, we finally get a glassy morning with 2 ft E swell, period 9 seconds, and energy of 95 (weak). That could be fun for a small-wave cruiser, but nothing to get worked up about.
Overall, there’s no real standout session here. The best bet is Monday morning, the 24th of August, if you’re after clean tiny waves with light offshore wind. Everything else is either too small, too onshore, or just plain poor. This is a tough run for L Jetty.

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.
