The Lowdown

Alright, this is Rusty. Let's have a look at what’s on the table for Ansteys over the next couple of weeks.

Right off the bat, I gotta be straight with you – the first week or so is looking pretty average. The swell is there, but the wind is just constantly messing things up. There's a lot of cross-onshore wind making things choppy, and the scores reflect that. You’ll see some waves, but mostly it’s a frustrating wait for decent conditions.

Looking at the start, Tuesday the 15th has a 7ft east swell, but it’s coming in with a cross-onshore wind, so it’s a bit of a bumpy mess. That pattern holds for a few days. The water temp is sitting at 69°, which is just a touch cooler than average for this time of year, nothing weird.

There’s one little window that catches my eye. Thursday afternoon the 17th. The swell drops a bit to 5ft from the east, but the wind goes super light, almost calm. The combined wave energy is solid at (1182), meaning there’s some push behind it. It’s the best looking session of that first week, but the crowds are known to show up here sometimes, so get in the water early if you can.

Then we hit a real rough patch. Friday the 18th gets a big pulse from the southeast – 10ft to 13ft – but it comes with heavy rain and a strong cross-onshore wind. That’s a messy, dangerous situation, really only for the most hardcore. The setup looks more interesting for the kite surfers than us paddle guys. That messy and windy pattern carries right through to the end of the month.

The real standout, and it’s a long way off, but worth marking on your calendar, is Sunday the 27th of September. The forecast is showing a small 3ft groundswell from the south, but the wind goes glassy. Absolutely glassy. That’s the best wind you can get for clean waves. The period is a short 10 seconds, so it’s not a big, powerful groundswell, but when it’s that clean, you can make anything work. The only downside is the swell is small, so you’ll need a longboard or a fish. The combined energy is (222), so it's weak, but the quality will be there. This is my pick for the best session of the whole run. Just remember, it’s a long way out, so don’t bank on it just yet.

Overall, it’s a tough outlook. There’s a lot of wind, a lot of chop, and not many clean options. Keep an eye on that Thursday the 17th afternoon and that Sunday the 27th morning. For everything else? Maybe go for a paddle, not a paddle-out.

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.
