The Lowdown
Alright, Rusty here. Let’s get into it.
First off, I gotta be straight with you – we’ve got a long stretch of nothing much on the cards for The South Jetty. For the first several days, it’s mostly tiny, weak, and messy. From Saturday the 22nd right through to the end of the month, we’re looking at waves mostly under 3 feet, with a lot of onshore or cross-shore wind messing things up. The swell energy is low, mostly sitting in the 20s and 30s (weak combined energy), and the conditions are just poor for surfing. It’s not until Friday the 28th afternoon that we see a pulse of something real.
That Friday afternoon, the 28th of August, we get a jump to 4 ft of S swell, with a short period of 7 seconds. The wind swings offshore from the west at 9 mph, so the surface should be clean. The combined energy climbs to 236 (moderate energy) and it’s the only time in the whole run we get a "good surf conditions" call. That’s your best bet, but with that short period, it’ll be a bit fat and soft. Still, it’s the stand-out session.
After that, we slide back into small, weak stuff through the end of August and into September. There’s a bit more energy showing up around the 1st and 2nd of September, with combined energy hitting the 140s and 160s, but the waves are still under 3 ft and the wind is messy – mostly cross or cross-onshore. The morning of Wednesday the 2nd is worth a look: 2 ft of SE groundswell with a 12-second period, and a clean offshore breeze from the WSW at 9 mph. That’s a long-period groundswell, which at a beach/jetty setup can be a bit straight, but if you pick your peak, you could get a fun, clean wave.
The water temperature is 79° on the first day, and that’s a whopping 6° warmer than normal for the time of year – very unusual, so you can leave the wetsuit at home.
Overall, there’s no big swell to get excited about. The standout is Friday the 28th afternoon for the biggest clean surf, and Wednesday the 2nd September morning for a clean, longer-period option. The rest is a whole lot of small and choppy. Crowds are a possibility here at The South Jetty, so don’t expect to have it to yourself.
Rusty.

Information about the The South Jetty Surf forecast
The above surf forecast table for The South Jetty provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The South Jetty can be found by selecting the local surf guide option on the grey menu. Our The South 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 (The South 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 The South 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.
