The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a bit of a slow run ahead at Jetty, with a long, quiet patch before anything worth paddling out for shows up.
Right now, the water temp is sitting at 72°, which is about normal for the time of year, so no need to dig out the thickest rubber just yet.
To be straight with you, the first week and a half is pretty flat. From Wednesday the 2nd right through to the morning of Monday the 8th, we’re looking at tiny, weak waves that don’t crack a decent score. The odd 2ft swell rolls in, but it’s either cross-on, choppy, or just has no energy behind it. The combined energy hangs around a weak 20 to 124 (weak to moderate), and the wind is doing us no favours. Not worth the paddle.
Then things start to get a little interesting. The morning of Monday the 8th of September sees the swell bump up to 3ft from the SW, but it’s cross-shore with a moderate breeze, and the period is a short, weak 5 seconds. That’s a miss. The afternoon of the 8th actually pushes 5ft from the SSW, but it’s a fresh cross-onshore, lumpy as hell, and the combined energy jumps to 167 (moderate). That’s a bit of a messy, blown-out wall for experts only if you’re desperate, but for the average surfer, it’s a no-go.
The real standout is the morning of Wednesday the 10th of September. We’ve got 3ft of S swell, period at 7 seconds, with a light 6 mph cross-offshore breeze from the NE. The combined energy is 112 (moderate), and the conditions are clean. This is the only window where the wind is right and the waves are surfable, but it’s still ordinary – just the best of a quiet run. The swell direction is from the S, which is a bit off from Jetty’s optimum SSE, but it’s the pick of the bunch.
After that, it’s back to tiny, weak swells and poor conditions through the rest of the second week. The afternoon of Thursday the 18th of September offers a bit more hope: 3ft from the ESE, period 8 seconds, clean cross-offshore wind, and combined energy up to 128 (moderate). That’s another day that’s surfable, but again, nothing to write home about.
So, the best on offer is the Wednesday morning of the 10th of September. It’s not a classic, but if you’re itching for a paddle, that’s your window. Crowds are *sometimes* a factor here, so you might have a few others with the same idea.
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.
