The Lowdown
G'day, Rusty here. Lookin' at this 16-day stretch for Ansteys, it's a bit of a mixed bag with some serious size comin' in. We gotta be patient, 'cause the first week is mostly a write-off, but there's a couple of days that are gonna get the heart pumpin', especially for the experienced crew. Right now, the water's sittin' at about 69°, which is a touch cooler than what we’d expect for this time of year.
The story starts off pretty grim. Monday the 14th is a complete no-go, with a howlin' 31 mph crosswind from the NE makin' a mess of any 8ft swell. That wind hangs around, and the whole first week is a battle against lumpy, choppy conditions, small waves, or just bad wind. Tuesday the 15th is only tiny 7ft E swell with light cross-onshore breezes, but it's marginal at best. The pattern is poor until we hit a real standout.
The one to circle on the calendar is Friday the 18th of September. The mornin' is lookin' prime: a clean 12ft ESE swell with a gentle cross-offshore wind from the N, makin' for some super clean lines. The combined energy is absolutely pumpin' at 3039, and the surf is gonna be powerful. That afternoon stays clean with a 10ft SE swell. But listen, this is expert territory. With the swell pushin' over 8ft, this is not a day for the learner. This is a day for the big-wave chargers at Ansteys.
Saturday the 19th still has plenty of size, with a 10ft SE swell and an 11-second period, but it gets messy as the wind swings NE and picks up. It's still a solid swell for those who can handle it, but the quality drops off. After that, the energy fades and the winds are messy again for the rest of the week.
There's a flicker of hope on Monday the 22nd of September when another pulse of 10ft S swell comes in, again with clean(ish) conditions, but the wind is light and cross-onshore, so it's not the perfection we saw on the 18th. It’s another big swell, so experts only.
The final week is more of the same: some swells, some average wind, and a lot of “why bother?” moments. The end of the month sees a bit of a drop-off in size. The 28th of September shows a 8ft swell from the NE with a gentle breeze, which might be worth a look for a more manageable wave.
So, the standout is undeniably Friday the 18th. It's the day the stars align for a short window of clean, powerful surf. After that, it's a waitin' game for the next clean day.
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.
