The Lowdown
Alright folks, Rusty here. Let's have a look at the local picture for the Jetty.
Honestly, the next two weeks are looking pretty grim for a proper paddle session. There’s a whole heap of poor conditions to wade through before we see anything half-decent. The first real glimmer of hope, and it's a small one, is a short window on the morning of Tuesday, the 4th of August.
For most of this run, the wind is all over the shop and the swell is either tiny or messy. The combined wave energy is weak, mostly sitting under 100 for the first few days, which tells you there's just no power. We get a big spike of energy on Monday the 3rd, but that’s accompanied by a strong, messy cross-onshore wind and even a risk of thunderstorms – that’s a skip day for sure.
The one standout, if you can call it that, is the Tuesday morning session. On the morning of the 4th, we’ve got a gentle offshore breeze from the N, cleaning up a 4ft S swell. The combined energy is a moderate 252, which gives it a bit of push, and the period is 8 seconds which is short-period wind swell, so it'll be a bit crumbly. It’s not going to be amazing, but it'll be the cleanest we see in this stretch. The Jetty is a breakwater setup and it’s very consistent, but you can expect a few other heads out there as crowds are "sometimes" an issue, so get in early. The water temp is sitting at 72°, which is about average for the time of year, so the small anomaly doesn't mean much – it'll feel normal.
After that Tuesday morning, it's straight back into poor conditions. The wind swings around, the swell drops off again, and we get a run of choppy, cross-onshore slop all the way through to the end of the 16-day window. There are a couple of glassy mornings on the 12th, but the swell is tiny at 2ft and 2ft with no energy behind it. Later in the second week, the swell tries to pick up on the 13th with 4ft from the SSW, but the wind is straight onshore and the period is a weak 6 seconds, so it’ll be a bumpy mess.
Really, if you’re itching for a wave, that Tuesday morning is your only realistic shot. Otherwise, it’s a long stretch of waiting.
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.
