The Lowdown
Alright folks, Rusty here with a look at what The South Jetty has cooking for us over the next couple of weeks. Gotta be straight with you, we're looking at a pretty quiet stretch to start, so patience is the name of the game.
The first real chance to get wet doesn't show up until Thursday, the 27th of August. Before that, it's pretty much a no-go. From now until that Thursday morning, we've got a solid stretch of tiny, weak waves with poor conditions. There's a window around Wednesday the 26th with a decent 16-second period groundswell, but the energy is weak at 72 and winds are messy, so it's a pass for paddle surfing—maybe one for the kite crew.
Things finally perk up on Thursday afternoon, August 27th, as a new S swell blends in. The South Jetty will see some 4ft waves from the south, with a moderate combined energy of 226. We've got light breeze and clean conditions from a cross-offshore wind. This is the best call in the first week, offering surfable waves, but it's still pretty ordinary. By Friday morning the 28th, it drops back down to 2ft and we lose the quality.
The standout window arrives early in the second week. On Monday, August 31st, the morning shows 4ft from the east with a clean offshore wind. Energy is moderate at 113, but the real highlight is Tuesday, September 1st. We get a solid 5ft of east swell with a combined energy hitting 332. The morning is glassy—absolutely glassy—with barely a breath of wind from the NNW. This is the best on offer for the whole outlook. The afternoon stays clean and surfable at 5ft. After that, conditions start to deteriorate again on Wednesday with a strong onshore flow.
So, to sum it up: don't bother paddling out until Thursday the 27th, and even then, keep your expectations low. The real one to circle is Tuesday, September 1st. That glassy morning with chest-to-head high east swell is your best bet by a long shot. The rest of the second week looks like it will drop off again.
Keep an eye on the forecasts, because on a quiet stretch like this, things can change.
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.
