The Lowdown
Alright, Rusty here. Let's have a good look at what Jetty has in store for us over the next couple of weeks.
Honestly, it's a pretty grim stretch for paddle surfing at Jetty. The first week is all but written off. You’re looking at a solid run of poor surf conditions from Monday the 24th through Sunday the 30th of August. Tiny swell, mostly cross-onshore or onshore winds, and a lot of chop. There's a bit of a lift on Friday the 28th morning with a 3ft swell from the South, but the period is a short, weak 7 seconds (combined energy 176) and the wind is cross-shore, so it’ll be a mess. Not worth suiting up for.
We finally get a bit of hope on Monday the 31st of August. The morning shows a 5ft SSW swell with a moderate cross-offshore breeze from the NW, which cleans things right up. Combined energy is 228, so it’s got some moderate grunt. The wind makes it look clean, and the longer period from the SSW is the best direction for this exposed break. It’s a breakwater setup, so it handles a bit of size, but at 5ft and very consistent, this is a genuine standout for the whole forecast. The water temp is a touch warmer than normal at 74°.
Then it’s back into the doldrums. The first week of September is a write-off too, with nothing but poor conditions and messy winds. As we push into the second week, around the 7th of September (Monday), we see some marginal conditions pop up. The morning has a 3ft ESE swell with a 9-second period and clean, cross-off winds from the ENE. The combined energy is 235, moderate, but the tide might be an issue. It’s a far cry from the 31st, but it’s the only other blip on the radar. The afternoon of the 7th has a similar swell but onshore wind, so forget it.
So, the one and only true standout here is Monday morning, the 31st of August. Get on it. The rest of the 16 days is a long, frustrating gap of flat or ugly conditions. It’s just one of those runs for this spot.
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.
