The Lowdown
Alright folks, Rusty here. We’ve got a 16-day outlook for Ansteys, but I gotta be straight with you – it’s a tough stretch. The water temp is about average for this time of year, nothing unusual there.
The first few days are a write-off. Thursday the 10th kicks off with a messy 7ft ENE swell (933 energy) and a crosswind, and it just gets worse. Friday through to the end of the following week is plagued by onshore winds and lumpy, blown-out conditions. There are a few days with surfable height, but the wind is just terrible. It’s a long, frustrating gap with no real recommendations.
Finally, we get a glimmer of hope on Tuesday the 15th. The afternoon looks like the standout of the whole period. The wind drops to glassy, dead calm, and we’ve got a clean 6ft swell from the east (506 energy). That’s the kind of window you wait for – clean, lined-up waves. It’s perfect for intermediates.
But hold on. The real kicker might be Friday the 25th of September. That morning shows a massive 12ft NE swell (2680 energy) with favorable wind and tide. But listen, that’s expert territory. That’s a big, powerful groundswell with a period of 9 seconds. For anyone but the most experienced crew at Ansteys, it’s going to be too big and unruly. It’s a promising, long-range call, but with a major caveat – it’s only for the brave.
So, the pick of the bunch? Tuesday the 15th afternoon for clean, glassy waves. And if you’re an expert, keep an eye on that Friday the 25th, but don’t get your hopes up too early.
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.
