The Lowdown
G’day, I’m Rusty.
Let’s talk about what’s shaping up at Ansteys. It’s a bit of a mixed bag this forecast period, with a long stretch of pretty average conditions before one standout window shows up. The water’s sitting at 70°, about what you’d expect for this time of year – no real anomaly there.
Right now, we’ve got nothing doing for the first couple of days. Friday the 4th is a write-off – 10ft of messy south swell but with a nasty 22 mph cross-onshore wind, and the combined wave energy is pumping at 1504, but it’s just lumpy junk. Saturday the 5th and Sunday the 6th are marginal at best, with small 3ft to 7ft swell and cross or cross-on breezes, so not worth paddling out for.
Monday the 7th morning is where it finally gets interesting. The swell drops to 8ft from the south, but now we’ve got a 17-second period – that’s proper long-period groundswell, and the wind is a clean cross-offshore from the NNE at 12 mph. The combined energy hits 3940, and it’s described as clean. This is the best on offer in the whole outlook – solid, powerful waves with good shape, but 8ft is only for experienced surfers. That long period means it might wall up a bit straight at a beach break, but Ansteys can handle it. The crowds are sometimes an issue, so you might have to share.
After that, it goes downhill fast. From Monday afternoon right through to mid-September, it’s mostly poor surf with strong onshore or cross winds, lumpy chop, and only occasional small windows of marginal knee-to-waist-high junk. Tuesday the 15th morning has a tiny 3ft south groundswell with a 12-second period and light wind, but it’s barely enough to get excited about.
Then, hold onto your board – Friday the 18th afternoon arrives with a bang. We’ve got 12ft of south swell at a 14-second period, light onshore wind from the SE, and combined energy of 4173. The forecast says wind and tide are favorable, but that swell is too big for this break. For the brave expert crew, it could be a heavy session, but it’s a warning – this is not for the faint-hearted.
The final weekend of the 19th is back to blown-out rubbish with near-gale winds.
So, the standout is Monday the 7th morning for clean, powerful waves. The other highlight is Friday the 18th afternoon, but only for the experienced crew who know what they’re doing in big stuff. The rest of the period is mostly a write-off, with a big gap of poor conditions from the 8th through the 17th.
Take it easy,
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.
