The Lowdown
Alright, let’s break it down. I’m looking at The South Jetty, and honestly, it’s a rough stretch. From Friday the 21st of August all the way through Monday the 31st of August, every session is poor surf. Tiny waves—0.7ft to 2ft—with short periods and weak energy (combined energy in the teens to 30s). Winds are mostly onshore or cross-onshore, making it choppy. A couple of clean windows on the 23rd and 24th, but with swell that small, it’s not worth it. The water’s at 79°F, which is 6°F above average—pretty unusual and warm.
The first real glimmer comes on Tuesday the 1st of September. The morning session is glassy with a light wind and a 3ft swell from the south at 6 seconds. Short period, but clean. The afternoon is better: 4ft from the south, still short period, but with a cross-off breeze and moderate energy (135). It’s not perfect, but it’s the best we’ve seen in two weeks. The South Jetty is a beach/jetty setup, exposed to swells, with an optimum direction from the southeast. This swell is from the south, so it’s a bit off, but it’s working. Crowds can pop up sometimes, so expect company.
After that, it’s back to poor conditions. The 2nd through the 5th of September are all small and choppy. The 5th has a 3ft and 4ft pulse from the south, but it’s onshore and messy.
So, the only real window is the 1st of September. The rest of the 16 days is a flat, frustrating run. The South Jetty is usually consistent, but this is a tough spell. Forecasts can change, so keep an eye 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.
