Table - best surf conditions forecast for Jetty over the next 16 days.
The Lowdown
Alright, let’s get this straight. The next 16 days are looking pretty bleak for any proper waves. We’ve got a long stretch of small, weak surf and mostly ordinary conditions. The good news is there’s a hint of something cleaner late in the window, but honestly, it’s a waiting game.
The first couple of weeks are a write-off. We’re looking at tiny, short-period swell with cross and cross-onshore winds messing up the surface. There are a few moments where it cleans up, like Wednesday the 12th at Jetty (Breakwater), where we’ve got glassy conditions and a clean look, but the swell is barely there at 2ft. Don’t get too excited.
The energy in the water is weak. Most days the combined swell energy is in the low two digits, like 53 or 66, and even when it bumps up to 140 on Saturday the 8th, the wind is still cross and the waves are just messy. It’s frustrating, ya know? Good energy, bad presentation.
We finally see a real change around the third week. By the 15th and 16th, we’ve got some offshore winds, which is a big deal for a spot like this. The swell is still small, but it’s clean. Saturday morning the 15th is looking promising with a 2ft swell and a light offshore breeze, and Sunday the 16th is similar. The 17th brings a better period swell at 9 seconds from the SE, but the size drops off, and the wind is stronger. Still, that’s the standout of the whole run. The 18th starts with dead calm and glassy conditions, but the swell is tiny.
And then we get to the 21st. Finally, something that’s actually surfable, not just a paddle. There’s a 3ft SW swell with a light offshore breeze on Friday morning, and it’s clean. The energy is moderate at 92, but it’s the best we’ve seen in a while. The swell direction is from the S, which is good for this break, and the period is short at 6 seconds, so it won’t be world-class, but it’s rideable. The afternoon looks even better with some light rain and glassy conditions on a slightly smaller 3ft swell from the SSE.
That’s your window. The last Friday is the day. Everything before is just a tease. The water is 73°, which is about normal for this time of year, so a spring suit is all you need.
There are long gaps of nothing in this forecast. But keep the faith, when it’s flat for this long, it tends to come back with a bit of punch.
Stay stoked.

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.
