The Lowdown
Hey crew, Rusty here again with a look at the surf in good ol’ feet and miles. We’ve got a bit of a slow start, but there is one absolute gem hiding in the second week.
Starting off, Wednesday the 12th is total junk – onshore wind, messy, no point in looking. Thursday the 13th morning is the first little window. At Ansteys, the water temp is sitting at 71°, right on average for this time of year. There’s a clean 6ft ESE swell with an 8-second period, but the wind goes glassy from the SSW. The combined energy is moderate at 523. It’s rideable for intermediates, but don’t expect fireworks. After that, from Thursday afternoon through the weekend of August 16, the wind shifts cross-shore and the quality tanks. There are waves, but they’re ugly.
Now the one to really get excited about: Monday the 17th afternoon. This is the standout session of the entire 16-day forecast. The swell is a solid 6ft out of the ENE, period of 10 seconds, and combined energy is strong at 1029. But the key is the wind – glassy out of the SSW. This means absolutely clean, lined-up waves at Ansteys. For intermediate to experienced surfers, it’s going to be as good as it gets in this window.
From Tuesday the 18th all the way through to Wednesday the 26th, it’s a long, frustrating stretch of poor conditions – strong winds, cross-chop, and messy waves. On the 24th there’s big S groundswell with a very long 18-second period and combined energy over 1900, but the cross-onshore wind ruins it for paddle surfing. That kind of long-period energy really needs a point or reef to work right.
Finally, Thursday the 27th morning offers a last chance. The swell hits 7ft from the NE, period of 7 seconds. Winds are light and cross-onshore, so not ideal, but combined energy sits at 695. That size is expert-only territory, and the short period won’t help the shape. Still, better than most of the other days.
Bottom line: Monday the 17th afternoon is your best shot. Everything else is mostly a wait-and-see.

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.
