The Lowdown
Alright, let’s get into it. The 16-day window starts with a big fat nothing. The South Jetty’s got no real surf on offer for the first week and a half. It’s a tough stretch – small, weak, and mostly messy. We’re talking a solid 10 days of "poor surf conditions" with tiny waves and choppy wind. The energy is just not there. The combined energy of all swells directed here is barely hitting double digits most days, like 14, 20, or 26 – that’s weak. You’d be wasting your time.
But hold on. Things start to flicker around Wednesday the 19th of August. The morning still looks poor, but by Wednesday afternoon, the swell bumps up to 5ft from the south, with a period of 6 seconds. The energy jumps to 203 (moderate), and the wind is light and cross-shore. It’s still marginal – the score’s a 1 out of 10 – but it’s the first real sign of life. The water temperature is 77°F, which is a touch warmer than normal for this time of year, about 3°F above average. That’s nice, but the surf is still ordinary.
Then Thursday the 20th of August morning is the best it gets. The South Jetty will see 3ft swell from the SSE, with a 7-second period, and a light NNW cross-offshore breeze. The combined energy is 168 (moderate), and it’s clean. This is the standout. It’s not pumping, but it’s the only session that’s actually surfable without fighting the wind. The swell is small enough for beginners and intermediates, and the offshore wind will keep it tidy. The direction is from the SSE, which matches the optimum swell direction for this exposed beach/jetty setup. The break is consistent, so you can count on a few waves. Crowds are sometimes a thing here, so you might see a few others out.
After that, it drops off again. Friday the 21st and Saturday the 22nd see the swell shrink back to 2ft or less, and the wind gets messy. The energy plummets back to the 40s. The last week of the outlook is a write-off – small, choppy, and no real push. Nothing in the second week is worth planning around.
So, if you’re itching for a paddle, your only real window is Thursday morning the 20th of August at The South Jetty. It’s not a classic, but it’s clean, small, and the best we’ve got. The rest of the 16 days? Leave the board in the car.

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.
