The Lowdown
Alright, Rusty here, let’s talk about what’s on the cards for the local zone.
Honestly, the next week and a half is pretty grim. We’ve got a long stretch of poor surf conditions, with only a couple of blips worth paddling out for. The whole 16-day window has a big gap of nothing good from now until the 21st, so don’t even bother looking at the beach until then.
The first real glimmer of something surfable comes on the morning of Tuesday, 18th August. It’s only a 2ft swell from the SE, but the period is a long 10 seconds, so there’s a bit of shape to it. The wind is light and clean, but the wave energy is weak (82). It’s really just a splash-around session, not a stand-out.
Everything changes on the morning of Saturday, 22nd August. That’s your pick of the whole forecast. The Jetty (breakwater) is looking at a clean 3ft swell from the SE with a solid 12-second period. The wind is glassy, dead calm, and the water will be mirror-flat. The combined energy is moderate at 244, so there’s enough push. This is a true morning session, with that long period likely making the waves peel a bit better off the breakwater. Crowds are possible, but for a 3/5 rated spot with glassy conditions, it’s worth the company.
The water temp is about average for this time of year, nothing wild.
The 22nd is the standout. The rest of the window is a write-off, with strong winds and messy conditions. It’s the kind of setup that looks more interesting for kite surfing than paddle surfing on most days.

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.
