The Lowdown
Alright, Rusty here. Let’s take a look at what’s on offer at Ansteys over the next couple of weeks.
To be honest, the next week-plus is a bit of a rough patch. The swell direction from the east has decent energy in it at times, but the wind is just not playing ball. It’s going to be a long wait for a proper window. From now through to Friday the 18th, the conditions are mostly messy with cross-shore and cross-onshore winds, and the quality is just not there. It’s a tough stretch, with plenty of those days seeing combined swell energy in the 134 to 2541 range, but it’s all blown out and choppy. The Saturday the 19th is the first real glimmer of hope.
Now, if you can sit tight, there is one standout. The weekend of Saturday the 19th. On the Saturday morning, it all comes together for a short while. The wind goes glassy – a light S breeze at 3 mph, which is about as clean as it gets. Swell is a modest 4 ft from the ENE with a short period of 5 seconds, so the combined energy is a weaker 226. But that glassy, clean surface is the key here. For a break that can be inconsistent, catching it when it’s this pristine is the move. It won’t be huge, but the quality will make up for it.
The rest of that weekend and into the following week is mostly back to cross-shore winds and poor conditions, though there is a very long period groundswell showing up on Thursday the 24th afternoon. A 4 ft swell from the south with a 15-second period, and the combined energy jumps to 1078. The wind is a gentle cross-shore from the NE. This is a classic case of a long period south swell hitting this east-facing spot – it might be a bit straight and fat, but if you can find a bank or a bend in the reef, there could be a sneaky clean wave or two.
Last thing – the water temp will be about average for this time of year, no real surprises there.
Rusty out.

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.
