The Lowdown
Alright, Rusty here again. Let’s break down what’s happening at Ansteys over the next couple weeks.
Water temp is about 70°, which is pretty normal for this time of year. Nothing unusual.
The first week is a total dud. From Sunday, August 30th all the way through to the start of September, the wind is blowing cross or cross-onshore, the swell is small and the conditions are just plain poor. The wave energy is weak to moderate, like 616 or 527, but it doesn’t matter because it’s all lumpy and messy. Not worth getting wet.
Monday, September 7th, there’s a tiny window of light wind but the swell drops right off. Marginally better, but still nothing to write home about.
The best chance you’ve got is around Tuesday, September 8th. That morning we see a 1.9m groundswell from the SSE with an 11-second period, light cross-shore wind, and combined energy climbing to just over 1000. That’s the standout window. It’s still a marginal call, but it’s the closest thing to a good wave in the whole forecast. Wednesday the 9th also has size – 2.0m from the SE – but the wind gets moderate and lumpy.
The second week gets big and ugly. Saturday, September 5th is a monster – 7.0m swell from the south with a 12-second period, but it’s blown out by a strong breeze, cross-onshore. Wave energy is huge at 13264, but it’s a mess. Sunday the 6th, the swell is still big at 3.5m from the SE, but the wind goes lighter and cross-shore. The computer says conditions are favourable, but the swell is too big for the break unless you’re a proper expert.
Later, around the 10th and 11th, we get some nice long-period groundswell from the south, but the wind is still cross-shore and the surf is only marginal. Wave energy is strong (around 1700), but it’s not lining up perfectly.
Honestly, the only real standout in this whole 16-day stretch is the morning of Tuesday, September 8th. It’s a promising but not locked-in call – light winds, a good 1.9m groundswell from the SSE, and moderate energy. Keep an eye on it. The rest is either flat, blown out, or way too big for this spot.
I’d say sit tight for the next week, then try your luck on the 8th.
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.
