The Lowdown
Alright, Rusty here. Let’s break it down.
Honestly, mate, this is gonna be a tough stretch. The forecast window is 16 days long, but for most of that time, it’s a ghost town. We’re looking at a solid 13-day gap at the start with nothing worth paddling for. The surf is just too small, the wind is messy, and it’s all poor surf conditions. You’d be better off waxing your board and staring at the wall. From the 29th of August all the way through to the morning of the 11th of September, it’s a write-off – tiny 1 to 2 foot waves, short period, and cross-onshore or breezy cross-shore chop. Not a single wave worth chasing.
Then, finally, on the morning of Friday the 11th of September, we get a little glimmer. Jetty is the only spot on the radar, and it’s a breakwater setup. The swell is a tiny 2 feet from the SSE with a period of 8 seconds, and the combined energy is weak (75). Not much to write home about, but the wind is offshore from the NNW at 12 mph, which is a solid clean-up crew. The water temp is sitting at 72°, which is pretty normal for this time of year. It’s surfable, but very ordinary. It’s the only option, and it’s a beginner-friendly size, but don’t expect much.
The next real tick is Saturday the 12th of September, morning. Jetty again, with a small 3 foot easterly swell, period a short 6 seconds, and only 60 combined energy. The wind is light cross-off from the west at 6 mph, so it’ll be clean. Again, it’s surfable but nothing special. Crowds are *sometimes* an issue here, so you might have a few others scratching around.
If you’re desperate, the morning of Friday the 11th and Saturday the 12th are your only real chances. Beyond that, the 13th of September has a clean offshore wind but the swell is dropping to 2 feet and then 1 feet. It’s a long wait for very little reward.
Keep the expectations low, and check back in a few days. The forecasts can change. Rusty out.

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.
