The Lowdown
Alright, Rusty here. Let’s break down what’s in store for the next couple of weeks.
Honestly, it’s a slow start. The first surf that’s even worth a mention doesn’t show up until Monday the 7th, so we’ve got a few days of flat or junk to get through. That’s a long stretch with nothing to get stoked about.
The only spot we’ve got on the radar is Ansteys. This is an exposed, east-facing break, and it’s a bit of a fickle one—it’s *inconsistent*, so it doesn’t always turn on. When it does, it needs an east swell to really work, and the ideal direction is dead east.
Water temp is about 69°, which is pretty normal for this time of year, so no surprises there.
The first real glimmer of hope is on Monday, 7th September. The morning is the window. We’ve got a solid 7ft south swell pumping in, with a super long period of 17 seconds—that’s proper groundswell. The combined energy is a strong 3089, so there’s a lot of power in the water. The wind is blowing a moderate cross-offshore from the north-northeast at 16 mph, which should keep the faces clean. The catch is that long-period south swell at a beach break like Ansteys can sometimes be too straight and not offer the best shape, but the clean conditions make it worth a look. This is the best on offer, but it’s still a bit of a gamble given the spot’s inconsistency.
Monday afternoon gets messy with the wind swinging around, so don’t be late. The morning is the move.
After that, it’s back into a slog of onshore junk and cross-chop through the rest of the week. There’s a brief moment on Saturday, 12th September in the afternoon where the wind drops to glassy and the swell is 5ft from the south. That’s a tempting window with clean conditions, but the energy is moderate (473) and the consistency is poor. It’s a maybe, but nothing to get your hopes up.
The rest of the second week is a write-off—windy, lumpy, and mostly poor surf. Nothing else really stands out as a must-surf.
So, to wrap it up: if you’re keen, Monday morning the 7th is your best bet, but don’t expect perfection. After that, it’s a long wait for anything clean.
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.
