The Lowdown
Alright, let’s get this out there. The South Jetty is looking at a pretty grim stretch for the next couple of weeks. To be straight with you, we’re looking at a big ol’ gap of flat, junk surf for the next ten days or so. It’s not gonna be worth paddling out for a wave that’s barely a ripple.
From Sunday morning the 9th right through to the 20th, it’s all tiny, weak, and mostly messy. We’re talking ankle-biters in the 0.7ft to 2ft range, with the swell coming from the south or southeast, but it’s got no push behind it. The energy is weak too, with values mostly in the single digits to the low 50s. There’s a bit of a pulse on the 17th and 18th, but it’s all cross-onshore chop, so it’s not doing anyone any favors. The jetty will be there, but it just won’t be breaking with any sort of form. There’s a little moment on the 19th with a longer period swell, but it’s still pretty weak and onshore, so don’t get too excited.
The best you can say for that first week and a half is that there are some clean windows with offshore winds, like on the morning of the 11th and the 14th, but the swell is just too small to matter. It’s a waiting game.
Now, as we roll into the back half of the window, things start to look a little less hopeless. The 21st of August, a Friday, sees a bit more life with a 2ft SE swell and clean offshore NW winds. It’s still small, but by the afternoon it might be just about surfable – a one-star kind of day. The energy is picking up to the 50s and 60s, so there’s a little more push there.
Then, the standout of the whole period looks like the 24th, a Monday. The energy jumps up to 118, which is the only moderate reading we get, and the swell is a bit bigger, hitting 3ft from the ENE. It’ll be a clean morning with a WSW cross-off breeze. It’s still not a big day by any stretch, but it’s the best we’re gonna get. The period is short, so it might be a bit crumbly, but it’ll be the most surfable day of the whole outlook.
So, yeah, it’s a rough run. The jetty is consistent but the waves are not. You might get a couple of grovel sessions in on a longboard, but don’t expect anything hollow. It’s more of a “get the wetsuit on for the sake of it” kind of fortnight. Keep an eye on the 24th, that’s your best bet.

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.
