The Lowdown
Alright, Rusty here, let’s break down Ansteys. Gonna be honest, the next week and a half is a bit of a flat, choppy bummer. The real juice doesn't show up until later, so we’ve gotta sit tight.
Water temp is about 70°, which is dead average for this time of year – nothing weird there. The only break in the game is Ansteys.
We start off with a little hope on Saturday the 15th with an east swell running 5 feet, but the wind is cross-shore from the northeast at 9 mph. The combined energy is so-so (447), and the period is a short 10 seconds, so it's gonna be lumpy and weak. It’s barely worth a paddle. Sunday the 16th is more of the same, maybe a little bigger in the arvo at 6 feet, but that cross-shore wind picks up to 16 mph. Not worth it.
There's a big dry spell here. From Monday the 17th straight through to Friday the 21st, the swell drops into the 2 to 4 foot range with short, weak periods. The winds aren’t your friend either, mostly cross or cross-on. You’re looking at about five days of knee-high slop.
Now, here's a little flicker. On Saturday the 22nd, the morning glass-off might give you a window. There’s a tiny 3-foot east-northeast swell with a light cross-off breeze, and the energy is still low (105), but the clean conditions will make it the most user-friendly wave in the run. It’s not a barnburner, just the best of a bad lot.
Hang onto your board for Sunday the 23rd. A big southerly groundswell hits, pushing 12 feet with a period of 14 seconds. The combined energy jumps to a massive 4885. But—and it’s a big but—the wind is a strong cross-shore at 25 mph and it’s messy. This is more of a kite-surfing show than a surf session.
The real standout is Monday the 24th. The swell is 10 feet from the south, with a very long period of 18 seconds. The combined energy is a thumping 6131. The wind is light and onshore from the south-southeast, but the problem is the size: 10 feet at a beach break like this is expert-only territory. That long period is gonna make it pitchy, and at a beach break, it might just close out straight. It’s too big for most, but for the brave few, it’ll be a wild ride. Tuesday the 25th is still big at 8 feet, but the cross-shore wind from the northeast at 19 mph will make it lumpy.
The rest of the window fades out. Thursday the 27th gets messy with strong winds again, and by the 30th, another spike of 10 feet shows up, but with strong onshore winds. Nothing to write home about.
If I’m calling it, the only date to circle is Monday the 24th for the big, clean (wind-wise) southerly groundswell. It’s for experts only. The Saturday the 22nd morning is a low-key, clean fun session for the log. Otherwise, it’s a long wait.
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.
