The Lowdown
Alright, let’s get into it. Look, I’m gonna be straight with you—this is one of those outlooks where you might wanna dust off the kite gear or just take the dog for a walk. The next two weeks here at Jetty aren’t exactly going to have us scrambling for our wetties.
The whole stretch starts quiet and pretty much stays that way. For the first week, from Thursday the 6th through to the 12th, we’re looking at weak, short-period swell hanging around the 2ft to 4ft mark, mostly from the south or south-southwest, and the period is stuck at 6 seconds. That’s pure windswell—no grunt, no real shape. The combined energy readings are weak, sitting mostly between 26 and 175, so it’s flat and messy. And the wind? It’s cross, cross-on, or just lumpy the whole time. No clean windows for the paddle crew. A few mornings look clean, like the 12th with glassy conditions and a slight southerly bump, but the swell is just too small at 2ft to get excited about. This is beginner-level dribble at best.
Now, there’s a glimmer right at the tail end. Wednesday the 19th and Thursday the 20th finally show a bit of life. The 19th morning has a clean 4ft southerly swell with moderate energy (132), and the wind is offshore from the northwest. That’s the standout window—clean, lined-up, and a bit of push. The period is still short at 6 seconds, so it’s not groundswell quality, but for this stretch, it’s the best on offer. The afternoon on the 19th stays clean with 4ft and offshore breezes. Then Thursday the 20th morning keeps that trend with 2ft and a gentle offshore from the northwest, making it clean and rideable for a longboard or a foamie. After that, it fades again into small, onshore slop through to the 21st.
Crowds are listed as possible at Jetty, but honestly, with conditions this average, you’ll likely have it to yourself. The water temp is 73°F, which is about normal for this time of year, so no surprises there.
If you’re dead-set on surfing, your best bet is Wednesday the 19th into Thursday the 20th—early, with an offshore wind and that 4ft southerly swell. It’s not gonna be epic, but it’s the only real window we’ve got.

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.
