The Lowdown
Alright folks, Rusty here. Let’s break it down.
Well, it’s a bit of a slow start for Ansteys. The first few days are looking pretty average – nothing to get excited about. Friday the 21st and Saturday the 22nd have some small swell, but the wind is either cross-shore or onshore, and the energy is weak (461 and 108). It’s a real struggle to find a decent wave.
The pattern really opens up as we head into the end of August and the start of September. The best bet in this whole outlook is the afternoon of Wednesday the 2nd of September. We’ve got a 4ft swell from the E, and the wind is forecast to be glassy. That’s a major positive – clean, smooth conditions. The water temperature is nothing unusual for this time of year, so it’s comfortable.
The swell is a bit short period (8 seconds), so it won’t have the power of a groundswell, but for a clean, cruisy session, that’s the standout. The combined energy is moderate (225), so there’s enough to have fun without it being a washing machine.
A couple of other days might be worth a look if you’re desperate. The mornings of the 29th and 30th of August have a moderate 7ft swell from the ENE, but it’s a short period (8 seconds) and the wind is cross-shore, so it’ll be a bit lumpy. It’s not the best quality, but there’s wave energy (1255 and 1213) if you’re willing to work for it.
After that, the first week of September has some bigger swells, but the wind is mostly onshore or cross-onshore, so it’s messy. The 1st of September has a 8ft swell from the NE, but it’s a short period and the wind is cross-on, so it’s not going to be clean. That’s more for the experienced crew who don’t mind a fight.
Looking further out, the 4th of September has a 6ft swell from the S, but the wind is onshore, so it’s blown out. The 5th has a 8ft swell from the S, but again, fresh cross-shore winds will ruin it.
So, overall, the standout is that glassy afternoon on the 2nd of September. The rest of the window is a mixed bag of average conditions and poor wind. Don’t expect much else.
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.
