The Lowdown
Alright, Rusty here again, but this time in feet and miles per hour.
Let’s be straight—it starts ugly and stays ugly for a while. Tuesday the 11th and Wednesday the 12th at Ansteys are a mess with strong, lumpy wind and chopped-up surf. No point even looking at it. The first real glimmer comes Thursday morning.
Thursday morning, 13th August is the clear standout. We’ve got a clean 6ft swell coming from the ESE, and the wind is dead glassy—literally calm, just 3 mph from the SSE. That is a rare gift. The wave energy is moderate at 502, so there’s enough grunt to get you moving. Ansteys can be inconsistent, and with the swell a bit south of its ideal easterly direction, you’ll want to pick your take-off spot. But with those perfect conditions, the few sets that roll through will be worth waiting for.
By Thursday afternoon the wind swings onshore and the quality drops. Friday and Saturday see the swell holding around 5ft to 6ft, but the wind is cross-shore and messy. The period stays short (8 to 10 seconds), so you’re looking at lumpy, weak waves.
From Sunday the 16th onward, it’s a long, painful stretch. The wind is almost always cross-shore from the NE, often blowing hard—20 to 30 mph gusts. The swell briefly pops up to 7ft on the 22nd and 23rd, but with a near gale or strong breeze ruining the surface, it’s more of a kite-surfing show than a paddle-surfing one. By the end of the period, the swell drops below 3ft and the conditions are just poor.
So here’s the deal: you’ve got one window, Thursday morning the 13th. Get it while it’s good because after that, the reefs will be quiet for a long time.

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.
