The Lowdown
Alright, Rusty here. Let’s look at what The South Jetty has cookin’ for the next couple weeks. Honestly, the start is a slog. For the first week and a half, it’s weak and poor. Waves barely crack 3ft, the combined energy is in the low weak zone, and the wind is messy – often onshore or cross-onshore, keeping things choppy. The water is running about 77°F, which is much warmer than usual for this time of year, so that’s the only comfort while you’re sitting around waiting.
Things finally turn the corner on Monday, September 23rd. That morning the swell jumps to 7ft from the east, period 8 seconds, and the combined energy hits the strong range (638). The wind switches clean and cross-off from the west. By afternoon, it’s 8ft east swell with a 9-second period and a combined energy of 866. That’s legitimate size and power. Tuesday the 24th stays solid – 8ft east swell, 10-second period, combined energy over 1200, and clean cross-off winds from the north. This two-day window is the standout. The 24th afternoon is kicking right at the threshold for experts only. If you’ve got the skills, that’s your session.
After that, the swell backs down Friday the 25th with a longer 11-second period from the east-southeast, but the wind goes cross-shore and bumpy, so the quality drops. The weekend fades back into small, weak surf.
The only real standout is that two-day push: Monday 23rd and Tuesday 24th at The South Jetty. The water is still unusually warm, and crowds are possible, but the direction is right on the money for this exposed jetty. Get out there.
Rusty.

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.
