The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the South Jetty over the next couple of weeks. I’ll be straight with you—this is a tough stretch. We’re looking at a long, dry spell with barely a whisper of swell for days. It’s not going to be easy.
The water is sitting at a balmy 79°, which is much warmer than normal for this time of year, so at least the wait won’t be a cold one.
We kick off on Wednesday, 12th of August with nothing. Thursday, Friday, Saturday, and Sunday all come up empty. The first real flicker of hope doesn’t show until Monday morning, 17th of August. The swell is tiny, only 2ft out of the SSE, and the combined energy is weak at 52. The wind is light and cross-off from the NNW, so it will be clean. Honestly, it’s surfable but very ordinary.
Monday afternoon gets glassy, but the swell drops to 2ft. Tuesday and Wednesday are more of the same – small, messy, and not worth getting excited about.
Now, the best of a bad bunch. Wednesday morning, 19th of August, brings a slight lift. The swell stays small at 2ft from the SE, but the period hits 11 seconds, and the combined energy climbs into the moderate range at 121. That’s the best energy we see in the whole outlook. The wind is a light cross-onshore from the S, so it’s not perfect, but it’s the only window where the ocean has a bit of push behind it.
After that, it’s back to the doldrums. The rest of the week and into the next weekend is filled with tiny, choppy waves and onshore winds. There’s a brief moment of glass on Sunday, 23rd of August, with 1ft and 9-second period, but it’s not enough to make a day of it.
The final days, from the 24th through the 27th, offer nothing but small, sloppy conditions with the swell barely cracking 3ft. The best call for this entire 16-day window is the Wednesday morning, 19th of August. It’s the only time the energy shows up, and even then, it’s just a small, clean-ish wave for the patient surfer. Crowds are possible here sometimes, but on a day like that, you might have it to yourself.
It’s a lean run, folks. But that’s how it goes sometimes. Keep an eye on the sky.

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.
