The Lowdown
Alright folks, Rusty here. Let’s get right into it for Ansteys. The good news is there’s a real standout window coming, but you’ll have to be patient through a long stretch of average-to-poor conditions.
The first solid surf recommendation is for Monday, the 7th of September. The early morning is the clear winner. We’ve got a solid 10ft swell from the south, with a very long period of 17 seconds – that’s proper groundswell energy. The combined energy is a massive 4465 (strong to very strong), so there’s plenty of power. The wind is a light, clean cross-offshore from the north-northeast, which will keep the surface glassy. This is expert territory, though; at over 8ft, it’s only for the skilled crew. The water temperature is sitting at 71°, which is about average for this time of year, so nothing unusual to worry about.
Now, the gap. After that Monday morning session, things go quiet for a long time. From Monday afternoon right through to the 19th of September, the conditions are poor or marginal – mostly cross-shore winds, lumpy chop, and messy swell. It’s a tough stretch, with no real winners.
The next possible window shows up on Saturday, the 19th of September, in the afternoon. The wind swings to a light offshore from the south-southeast, which is a major positive. The swell is 8ft from the east-northeast, but with a short period of only 8 seconds, so it’ll be a bit weaker and more disorganised. The combined energy is 930 (moderate to strong). This is still on the big side for beginners, but the clean conditions will make it interesting for intermediate and above.
Then, on Sunday, the 20th of September, the morning is a write-off with strong onshore winds, so don’t bother.
The standout here is the Monday 7th of September morning session. That’s the one to circle on the calendar. It’s a proper, powerful, clean groundswell – a real treat for the experienced surfers. The rest of the period is mostly a waiting game.

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.
