The Lowdown
Alright folks, Rusty here. Let's get into it.
Right off the bat, I gotta be straight with you – this 16-day window for Ansteys is a tough one. We're looking at a long stretch of conditions that are less than ideal, with a whole lot of messy, cross-shore winds and poor surf quality. The water is sitting at a pretty standard 70°F, which is about what we'd expect for this time of year. The real kicker is that for the first week and a half, there's hardly a decent window. From Thursday the 27th of August all the way through to the start of September, the wind is a constant problem, coming from the NE or ENE, and it's just tearing the surface apart. The swell energy is moderate to strong, with values like 1347 and 1326, but it's all wasted on that cross-chop. It's a real shame because the swell size is actually there, between 5 and 8 feet, but with that wind, it's just a lumpy mess.
We then get a bit of a lull at the start of September, with smaller, weaker energy (around 200-300) and still cross or cross-on winds. It's not until the 3rd of September, Thursday morning, that we see a glimmer of hope. Swell picks up to 6 feet from the ENE, but the wind is light and cross-on. It's still a marginal call, but it's the best we've seen. Then, just as we think it might clean up, the conditions take a wild turn. On Friday the 4th of September, we get a massive spike in energy – 8593 and then 10890 – with an 18 to 20-foot swell from the south, but it's arriving with a near-gale cross-shore. That's just a washing machine.
The real standout, if you can call it that, is on Sunday the 6th of September. The morning session sees a 13-foot swell from the SSE with a 12-second period, which is a solid, powerful groundswell. The wind is a fresh cross-shore, and the energy is massive (3982). While the guidance says it's too big for this break, for the experienced crew with big-wave boards, it might be the only serious session on offer. The sheer size and power are there, but you'd be mad to think it's going to be clean. It's a brute, not a beauty.
Beyond that, the tail end of the forecast from the 7th to the 11th of September is just a mix of fading swells, cross-shore winds, and marginal conditions. Energy drops back to the hundreds, and the magic is gone. All in all, it's a bleak outlook for Ansteys. The best advice is to wait for a change in the wind pattern, because the swell is there, it's just being hammered flat by the elements.

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.
