The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s on the cards for Ansteys over the next couple of weeks.
To be straight with you, it’s a long, frustrating wait for decent waves. For the first several days, from Saturday the 22nd through most of the following week, the wind is just all wrong – mostly cross or cross-onshore – and the surf quality is poor. There’s a small, weak 2ft south swell rolling in on Saturday morning (22nd), but with a moderate cross-shore wind it’s not worth paddling out. The energy is a lowly 97 (weak), and the water’s sitting at 71°, which is about normal for the time of year. A couple of days in the middle of the week see a bit more size, but the wind stays messy, so you’re not missing much.
Now, mark your calendar for Wednesday the 26th. That’s where the magic is hiding. Wednesday morning, the wind goes glassy, absolutely dead calm. We’ve got a 4ft south swell pumping in with a very long period of 18 seconds. That’s a proper groundswell with serious energy (1061). This is the standout in the whole 16-day window – clean, lined-up swell. Just a heads-up, though: that long period can make beach breaks a bit straight, but on the right bank it’ll be pure gold. The afternoon sees the swell jump to 7ft with even more energy (2685), but the wind swings onshore, so hit it early while it’s glassy.
After that, the rest of the run is mostly blown out. Thursday the 27th and Friday the 28th have solid sizes (5ft to 8ft) but that fresh to strong cross-shore wind from the NE ruins everything – messy lumpy chop. The weekend of the 30th and 31st is more of the same: too much wind and poor quality. There’s a glimmer on Tuesday the 1st of September with a light breeze and a small 3ft east swell, but it’s marginal. The real kicker might be Saturday the 6th of September: a clean 4ft south-southeast swell with a cross-offshore breeze, but by then we’re well into the second week, so take that one with a grain of salt.
Overall, the absolute best bet is Wednesday the 26th, morning session. Get out there for that glassy, long-period groundswell. The rest is mostly a write-off.
Rusty.

Information about the Ansteys Surf forecast
The above surf forecast table for Ansteys provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ansteys can be found by selecting the local surf guide option on the grey menu. Our Ansteys 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 (Ansteys) 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 Ansteys 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.
