The Lowdown
Alright, Rusty here. Let’s get stuck into what’s on the cards for Jetty.
Look, I’m not gonna sugar-coat it – this stretch is looking pretty ordinary for most of the run. We’ve got a massive dry spell to start, with basically nothing worth paddling out for until Wednesday the 20th. That’s nearly a week of flat or junk surf, so don’t bother checking the cam until then.
The first real flicker of hope comes on Monday morning, July 20th. The swell jumps to a clean 4ft out of the south, with a 9-second period giving it a bit of push. The combined energy hits 234 (moderate), and the real winner here is the wind – a gentle offshore from the NNW. That’ll keep the surface glassy and the lines tidy. Jetty should be offering up some clean, rideable banks. It’s not epic, but after a week of nothing, it’ll feel like a gift. The spot is very consistent, so you can bank on it being there. Keep in mind it’s exposed, and the optimum direction from the south-southeast lines up pretty well with this south swell. It’s an intermediate-friendly size, so the groms can have a crack too.
After that Monday morning window, it fades quick. Tuesday morning (21st) still has a little 3ft south swell with a cross-off, but the energy drops right off (111). From there, it’s back to poor conditions and onshore crud for several days.
Further out, into the last week of July, there are a few pulses of bigger swell – particularly around the 23rd and 24th with 6ft to 6ft south-easterly swells – but the wind is utterly brutal. Strong cross-onshore and onshore winds (SSE, SSW) wreck any hope of quality. The combined energy gets into the 300s (strong) but it’s just blown-out, lumpy, and messy. Unless you’re into a beating, give it a miss. Honestly, that kind of setup looks more interesting for kite surfing than paddle surfing.
The standout is clear as day: Monday morning, July 20th. That’s your window. Go get it.
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.
