The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for Ansteys over the next couple of weeks. It’s a bit of a mixed bag, so let's get stuck in.
Right from the get-go, things are pretty grim. We've got a solid onshore flow messing up any chance of a wave for the first few days. Friday 11th, Saturday 12th – it's all crossed-up and lumpy with onshore wind. You're better off staying on the couch with a coffee.
We finally see a bit of a pulse around Sunday the 13th. The swell bumps up to about 5 ft from the east-northeast, but it's a short-period job (7 seconds) and we've still got a light cross-onshore breeze. It's only a low score for the morning and afternoon – marginal at best. The combined energy is moderate (533 and 427), but the wind just isn't doing us any favours.
Then we get a bit of a beast rolling in on Monday the 14th. The swell jumps up to 10 ft in the morning and a heavy 13 ft in the afternoon from the east-northeast. The energy readings are huge (1054 and 2277). Problem is, the wind is howling from the northeast at 30-37 mph with a strong cross-shore mess. This thing is going to be a washing machine. Too big and too messy for most. Honestly, that setup looks more interesting for kite surfing than paddle surfing. The combined swell energy is strong to very strong (1054-2277). This is expert-only territory, and even then, it's a battle.
Things settle down a bit for Tuesday the 15th. Swell drops back to around 7 ft from the east. It's still a bit choppy in the morning with a moderate breeze, but the afternoon gets interesting. The wind goes light, almost calm from the east, with the swell at 6 ft and a solid period of 9 seconds. The combined energy is moderate (619). It's not perfect, but it's the first real window we've had. That afternoon session could be worth a look if you can dodge the slight cross-chop.
Wednesday the 16th looks okay in the morning with a light offshore from the south-southeast and 5 ft of east swell (10-second period), but the wind swings hard onshore in the afternoon and ruins it. Thursday the 17th is more of the same – onshore winds spoiling a 5 ft swell.
Now, here's a real standout if you can wait. Far out on Sunday the 20th of September. We've got a proper long-period groundswell pushing in. The morning brings a 3 ft swell from the south with a *very long* period of 21 seconds and strong energy (1072). The afternoon bumps up to 4 ft with a 20-second period. The morning wind is light cross-shore. That is a clean, powerful wave. The crowd forecast says "sometimes", so there'll be a few out, but for a spot this inconsistent, when it lines up with that kind of period from the south, it could be truly special. Just keep in mind that long-period swell like that can sometimes close out at a beach break, so look for a bank that can handle it.
The final chance worth mentioning is on Friday the 25th of September. The afternoon shows a 4 ft south swell with a 13-second period and moderate energy (818). The wind is light from the east, leaving it clean. It's not the size of the 20th, but the conditions look solid.
So, best of the lot? For me, it's Sunday the 20th of September. That long-period south groundswell with light morning winds is the highlight. The second best is Tuesday the 15th of September's afternoon session with that small but clean window. The rest is mostly wind-slop or blown-out.
Stay salty.
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.
