The Lowdown
Alright, Rusty here again. Let’s break this down. The South Jetty is looking at a pretty quiet 16-day stretch, so don’t expect a classic.
The first few days, from the 14th to the 16th, are flat and messy. Tiny swell, 0.2ft to 0.5ft, with cross-shore and onshore winds making it choppy and not worth a look. The combined energy is weak, barely reaching double digits.
Monday the 17th is the first decent window. A 1.0ft swell from the SSE shows up, with a combined energy of 102 (moderate). The morning is the highlight – a clean offshore wind from the NNW, which makes the setup paddleable. The swell period is short, 7 seconds, so it’s not a groundswell, but it’s surfable. The afternoon gets onshore and messy. Water temp is about average for the year.
After that, it’s a long dry spell. From Tuesday the 18th right through to Sunday the 23rd, the swell stays tiny and the wind keeps it choppy or cross-shore. Combined energy is low, mostly in the teens and twenties. A real gap of poor conditions.
The second week is thin. The only bright spot is Friday the 28th morning. We get a 1.0ft swell from the ENE, with a combined energy of 94, and the wind goes glassy – a light southwest breeze, 5 km/h, making it clean. The period is short (6 seconds), so it’s not a groundswell, but it’s the best you’ll get. The afternoon gets chopped again.
For beginners, it’s all small. The 1.0ft days are okay for intermediates. The standout is Monday the 17th morning with the offshore wind, and maybe Friday the 28th morning for some clean, tiny surf. Crowds are sometimes an issue, so the quiet times might help.
Rusty out.

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.
