The Lowdown
Alright, this is Rusty, and I’m looking at the stretch ahead for Ansteys. We’ve got a bit of a mixed bag coming our way, with the first few days being pretty rough. The water temp is sitting at 72°, which is about normal for this time of year, so no surprises there.
The opening weekend is a write-off, honestly. Friday the 31st of July has some chest-to-shoulder high swell at 8ft coming from the SSE with a short, weak 9-second period, but that cross-onshore wind at 19 mph is just going to make it a lumpy, blown-out mess. The combined energy is moderate at 1060, but it’s not worth paddling out for. Saturday and Sunday are similar stories with cross and cross-onshore winds, keeping conditions poor. The energy picks up on Sunday morning with an 8ft SE swell at 11 seconds, giving us a combined energy of 1460, but the wind is still cross-shore, so it’s a bumpy ride.
Now, the real standout is Monday the 3rd of August. That’s the one to circle. Early morning, it’s glassy. The wind will be a light ENE breeze at 3 mph, and the swell is a clean 7ft from the SE with a 10-second period. Combined energy is moderate at 914, but the conditions are labeled as “glassy,” which means you’re looking at clean, smooth faces. This is the best bet for intermediate surfers. The swell size is a bit much for beginners, but for anyone with a bit of experience, it’s going to be fun.
After that, the surf drops off. Tuesday the 4th sees a smaller 5ft swell, but it’s cross-shore again. The rest of the first week into the second week is a mess of fresh to strong cross-onshore winds, with the swell jumping around in size. Around the 7th of August, we get a long-period 6ft S swell at 14 seconds, which is a groundswell. Combined energy is strong at 1417, but with a cross-shore wind, it’s going to be a bit lumpy. The long period will make it better at a point or reef, but at a beach break like Ansteys, it might break a bit too straight.
The second week looks grim. From the 8th of August onwards, it’s a lot of strong winds and messy conditions. A couple of days have decent swell sizes, like the 11th with 8ft, but the wind is near gale force, so it’s blown out. Not worth it. The 13th of August afternoon has a 6ft S swell with a 13-second period and a clean cross-offshore wind, but the energy is strong at 1435. It’s a possible session, but it’s a long way out.
So, to sum it up: your best bet is Monday morning, the 3rd of August. It’s the only time the stars align with glassy conditions and a decent swell. For the rest of the window, it’s mostly a waiting game.
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.
