The Lowdown
Alright folks, Rusty here. Let's have a proper look at what's on the table for The South Jetty over the next couple of weeks.
Well, I've got to be straight with you – this stretch looks pretty bleak for a while. The wave energy is just not there for the foreseeable future. For the next week and a half or so, we're looking at a real flat spell. The combined energy readings are mostly in the single or low double digits (5 to 32), which is just weak, weak energy. The swell heights are hovering around that 0.3ft to 2ft mark, and the periods are short, mostly under 8 seconds. That’s not surfable in any meaningful way. It’s going to be a long, quiet period right through until about the 19th of August.
There is a little flicker of hope on Wednesday the 19th of August, in the afternoon. We finally see the combined energy tick up to 106 (moderate energy). We get a 2ft swell from the SE with a much longer period of 12 seconds, which is proper groundswell. The wind will be a light offshore from the west, keeping it clean. It’s still small, so it’s not going to be a world-beater, but after such a long drought, any clean wave will feel like gold. Crowds are possible here, and for a spot that’s been flat for days, you can bet a few people will be keen.
Don't get too excited about the bigger numbers later on. Sunday the 16th of August shows a 4ft S swell, but with a terrible 5-second period and a strong cross-onshore wind. That’s a complete mess. For anything over about 2ft here, the quality just isn't holding up.
The water temperature is sitting at a touch warmer than normal, about 78°F, which is a nice bonus for the first mention.
Honestly, the only real standout in this whole 16-day run is that Wednesday afternoon session on the 19th. It’s a long way out, so keep an eye on it, but it’s the only window with decent energy, a long period, and clean wind. The rest of it? Just leave the board in the car.
Rusty.

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.
