The Lowdown
Alright, Rusty here again. Let’s talk feet and Fahrenheit.
The South Jetty’s gonna be a tough ticket for the next little while. There’s a big stretch of flat to poor conditions from Monday the 14th right through to Saturday the 19th. We’re talkin’ near a week with nothin’ worth paddlin’ out for, just tiny dribbles and messy wind.
First hint of life shows up on Sunday the 20th. That morning we see about 3ft of swell from the SSW with a period of 6 seconds and a light cross-offshore breeze from the WSW, keepin’ things clean. The combined energy is moderate (115). It’s not gonna blow your mind, but it’s surfable after that long dry spell. That afternoon though, the wind swings hard from the NE at 18.6 mph with rain showers, so get out early if you’re gonna go.
The following week sees the swell size bump up, but the wind just ruins it. Monday the 21st through Wednesday the 23rd sees waves from the E and ESE pushin’ 5 to 6.5ft, with combined energy gettin’ strong, hittin’ 559 (Wednesday morning). That’s decent power, but it’s all cross-onshore and onshore wind – 12.4 to 21.7 mph – makin’ it choppy and blown out. That size, over 5ft, is already pushin’ it for beginners, and with that wind, it’s a mess. A beach and jetty setup like this with that much onshore wind might actually look better for a kite surfer than a paddle surfer.
Now, Thursday the 24th morning is where we get a real standout. The wind goes light offshore from the W at 6.2 mph, glassin’ up a 3.6ft swell from the E with a 9-second period. Combined energy is moderate (204). Conditions are clean, and that’s the best window in the whole 16 days. It’s not huge, but it’ll be shaped and fun, especially for intermediate crew. That afternoon the wind turns light cross-onshore, so don’t sleep on that morning session.
After that, we trickle back down. Friday the 25th and Saturday the 26th are small and messy again. Sunday the 27th morning offers a brief clean window with 3.6ft from the ESE (147 combined energy), and Monday the 28th morning has a clean 3.3ft from the ESE with offshore wind from the NNW – another solid option for a quick session. Tuesday the 29th finishes off with a clean morning (2ft) and a moderate offshore in the afternoon (3ft from the ENE), but it’s small and the energy is weak.
The water temp is 75.7°F, which is much warmer than normal for this time of year – over 5.4° above average. That’s very unusual, so you can leave the thick suit at home.
Overall, the best bet is Thursday the 24th morning. Get it while it’s clean. The rest is a game of pickin’ the cleaner windows in between the wind.

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.
