The Lowdown

Alright, mate, let’s call it like it is. The South Jetty has got nothing going for it over the next 16 days. Every single session is a dud – poor conditions, tiny waves, and mostly chopped up or flat.

First up, Monday the 7th: you’ve got a 2ft east swell, period around 10 seconds, with a north cross-off breeze in the morning making it look clean. But the energy is weak at 49. Water temp is a wild 77°, a full 6° warmer than normal – that’s crazy warm for a jetty spot. Afternoon goes to trash with a cross-on wind. Tuesday the 8th flatlines to 0.7ft.

Wednesday the 9th gets a 35 km/h wind from the SSW in the afternoon, pushing up a 3ft south swell, but it’s short-period (5 seconds) and lumpy. Energy is still weak at 54. That’s more of a kite day than a surf day.

Thursday the 10th comes closest to something: morning has 3ft from the SSW, clean offshore wind, but a short 6-second period. Energy hits 92 – moderate but weak. Afternoon bumps to 4ft, energy at 192 (moderate), still with clean cross-off wind. That’s the best you’ll see, but it’s not a proper wave.

From Friday the 11th onward, it’s tiny. You get a few clean moments – like the 16th with 1.0ft offshore wind, or the 17th with 0.7ft clean cross-off – but it’s all useless. The 18th has a long 12-second period on a 1.0ft south-east swell, but it’s too small to do anything at a beach/jetty. The 19th gets a fresh 30-35 km/h cross-shore wind and 3ft swell, but it’s lumpy and poor.

The last few days, 20th to 22nd, are all tiny, cross-onshore, and choppy. No hope.

The bottom line: The South Jetty is flat and poor the whole way through. There’s a real gap in surf here – the whole 16 days. If you’re dying to get wet, Thursday the 10th afternoon with 4ft and clean wind is your only shot, but it’s a long way from good. Stick to checking the forecast again later.

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.
