The Lowdown
G’day, Rusty here. Let’s talk about Ansteys. Bit of a slow burner, but there’s a couple of windows worth paddling out for.
The first real chance to get wet is Tuesday the 21st of July. We’ve got a solid 5ft swell out of the SE with a 12-second period, pushing a decent amount of energy (561). The water’s sitting at 74°, which is a touch warmer than normal for this time of year – feels good on the skin. The morning is looking alright with a light cross-breeze, but it’s not perfect, just marginal. If you’re keen, the morning session is the one, but don’t expect it to be firing.
After that, things go quiet. Wednesday the 22nd through to the end of July is pretty grim – the wind swings around and gets messy, and the swell drops off or gets chopped up. Thursday the 24th brings a bit of size with 6ft, but it’s a short-period 8-second S swell and the wind is cross-onshore and lumpy. Not worth it. There’s a long stretch of poor conditions, with only a few days offering any hope.
The standout, and I mean the real standout, is Thursday the 30th of July. The morning is glassy – dead calm. That’s rare as hen’s teeth. The swell is 5ft from the ENE with a 9-second period, and the energy is pumping (597). For a break like Ansteys, which is exposed and inconsistent, this is about as good as it gets. Clean, glassy conditions, decent size, and the wind is offshore from the ENE. If you can only surf one day in this whole forecast, this is the one. Get on it early.
Looking further ahead into the first week of August, the swell gets massive. Sunday the 2nd of August morning has a tiny 1.0ft, but by the afternoon it jumps to a huge 13ft from the S (12 seconds, 4414 energy). That’s proper big, and the wind is light cross-shore, but honestly, for Ansteys, this is too big for most folks. It’s a deep-water spot, but anything over 8ft is for experts only. The following Monday and Tuesday are even bigger – 15ft and 12ft – with long-period groundswell (14 seconds). That’s a lot of water moving around. The wind is cross-shore, but the size is intimidating. This is not a beginner’s wave. The energy readings are off the charts (12344 on Monday morning). If you’re an experienced local, you might love it, but it’s going to be a heavy, powerful day.
After that, things settle down a bit. Wednesday the 5th of August morning has 6ft from the SE (12 seconds, 1083 energy) with light cross-shore winds. It’s a bit marginal, but cleaner than the chaos before it. Still, nothing beats that glassy Thursday morning on the 30th.
So, bottom line: the first week is a write-off, but don’t lose hope. The 30th is your golden ticket. The second week brings monster swell for the big-wave crew. Stay safe out there.
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.
