The Lowdown
Alright, Rusty here. Let's take a look at what's on the table for the Jetty.
Honestly, it's a pretty grim stretch ahead. The water's a touch warmer than normal for this time of year sitting at 72°F, but that's about the only thing that's slightly interesting. The Jetty is a breakwater setup that's very consistent, but for the entire first week and a half, we're looking at tiny, weak, and messy surf. The combined energy values are all below 100, barely registering anything, and the swell direction is coming from the SE and ESE, which isn't the optimum for this spot. The first few days are a write-off with onshore winds, stormy conditions, and waves too small to do anything with.
Even when the wind does go offshore or clean around the 4th and 5th of September, the swell is barely 1ft to 2ft. It's a glassy, empty ocean that looks pretty but offers nothing ridable. This blank run stretches right through the first week of September.
Then, out of nowhere, we get a glimmer. On the morning of Sunday, the 13th of September, we see a real uptick. The swell jumps to 5ft from the South with a combined energy of 243, which is a moderate kick. The wind is a light, cross-off breeze, so it'll be clean. The sequence even says "expect good surf conditions". This is the standout of the whole forecast, but it's a long way out, so treat it as promising but not locked in. The Jetty will be the only game in town, and while a 5ft south swell with decent energy is a solid prospect, the short period of 7 seconds means it won't have that groundswell punch. It'll be a bit lumpy and sectiony, but after all that nothing, it'll feel like a gift.
The Monday morning after is still surfable at 4ft with clean offshore winds from the NNW, but the energy is already dropping back. The rest of the run after that fades back into tiny, poor conditions.
So, my call is simple: don't even bother looking at the Jetty until the morning of the 13th. That's your one window. Everything else is a skunk.
Rusty.

Information about the Jetty Surf forecast
The above surf forecast table for Jetty provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jetty can be found by selecting the local surf guide option on the grey menu. Our 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 (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 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.
