The Lowdown

Righto, let’s have a look at what’s coming our way. Over the next couple of weeks, we’ve got a bit of a mixed bag, but nothing too crazy. There’s a solid pulse of energy mid-period, but the wind’s gonna be the main player here, making a mess of things more often than not. The first real chance for a surf won’t be until late in the piece, so we’ve got a fair wait on our hands.

The only spot on the radar is Ansteys. This break is inconsistent, so we need to be patient. The water temperature is sitting at 68°, which is a bit colder than normal for this time of year (anomaly of 2°F colder), so you’ll want the 4/3.

The first half of the forecast is pretty grim. Sunday the 13th kicks off with a 3ft easterly swell, but it’s got a light cross-onshore breeze messing it up, and the wave energy is weak (233). Sunday arvo gets worse with a fresh NE breeze. Monday the 14th is a write-off – a 31 mph cross-shore wind and an 8ft swell that’s all over the shop (energy 917). That’s big, messy, and definitely not for beginners.

Tuesday the 15th sees a slight improvement with a 7ft E swell and a longer 10-second period, which gives it a bit more shape, but the cross-shore wind still has it looking a bit lumpy. Energy is moderate at 864. Wednesday the 16th morning could be a sneaky window – 6ft E swell, light cross-onshore, and the energy is still decent (604). But it’s still marginal.

From Thursday the 17th onwards, it’s mostly a write-off with strong onshore winds and messy conditions. Thursday arvo even has a 10ft S swell with a short 8-second period and a fresh cross-shore wind – that’s gonna be a washing machine, and probably more suited to kite surfing than paddling.

Now, after a long dry spell, things finally start to look interesting from Sunday the 20th. Sunday morning has a light cross-offshore breeze and a 3ft SE swell, but it’s small and inconsistent. The energy is weak (205). Still, it’s clean.

The real standout of the whole forecast is Monday the 21st morning. We’ve got glassy conditions – dead calm – with a 4ft ENE swell. The energy is low (276), but with that light wind and clean surface, it’s the best chance for a decent session. The period is only 7 seconds, so it’s a bit short period, but when it’s glassy, you take what you can get. This is the one to pencil in.

After that, we get a few more marginal days, but nothing really fires again. There’s a brief window on Wednesday the 23rd morning with a 7ft NE swell and a light offshore, but it’s short period and the wind swings nasty in the arvo.

So, to sum it up: a long wait, but Monday the 21st morning is your best bet for a clean, glassy surf at Ansteys. The rest is either blown out or too small. Keep an eye on the long-range though – things can change.

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.
