The Lowdown
Alright, let’s break it down. Rusty here, and I’m looking at what Ansteys has cookin’ for the next couple weeks.
First thing’s first: from August 14th all the way through the morning of the 23rd, it’s a ghost town. No surf worth a damn. The wind is all wrong, mostly cross or cross-on out of the northeast, and the swell is weak and messy. The combined energy barely gets above 300 at the start. Water temp is 70°F – pretty normal for this time of year.
The first real pulse comes on the afternoon of Sunday, August 23rd. You get a 6ft south swell with a 19-second period – that’s some serious groundswell, real long period energy. The combined energy (2186) is strong. But the wind is cross-shore from the NE at 15 mph, which will chop it up a bit. It’s a south swell, and Ansteys faces east, so the direction isn’t perfect. This one’s only for the keen, and it’s marginal.
The standout, no question, is the afternoon of Monday, August 24th. That’s a solid 7ft south swell, 14-second period, combined energy still strong at 1673. The wind is cross-shore from the NE at 15 mph – not glassy, but workable. For experienced surfers, this is the window. That size is over 5ft, so it’s not for beginners. It’s got grunt.
After that, it fades fast. The 25th and 26th are messy, and by the 28th the wind is fresh onshore, hitting 22 mph from the SSW. That setup on the 28th – 6ft from the NE with that onshore wind – honestly looks more fun for a kite than a surfboard.
Bottom line: the first week and a half is a wash. The only real highlight is Monday the 24th of August for the bigger south swell, but only if you’re solid and don’t mind a little chop. Everything else, leave it.
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.
