The Lowdown
Alright, grab your board. Let’s talk about what’s happening at Ansteys.
Overall, the next 16 days are a bit of a mixed bag. We’ve got some decent sized swell at times, but the wind is going to be fighting us for most of the run. There’s a lot of cross-shore and cross-onshore breeze, which will mess up the surface. The real standout is a single, raw day of power later in the second week.
The first real chance to get wet doesn’t come until Monday the 7th. The water temperature is sitting at 71°F, which is bang on average for this time of year—nothing unusual there. The swell is a solid 7ft of long-period S groundswell (16 seconds), so there’s heaps of energy in the water (2392). That long period is going to create some clean, powerful lines, but it’s a cross-shore NE wind at 15 mph, which will put a bit of a chop on the face. It’s not perfect, but it’s the most promising start we’ve got. The crowd factor is rated as "sometimes", so you might have some company, but it shouldn’t be a zoo.
The next big thing to keep an eye on is Tuesday the 15th. This is the one. We’re looking at a massive 12ft swell from the NE, with a combined energy reading of 2834. That’s serious power. The wind is a cross-shore SW at 22 mph, so it’s gusty, but the forecast calls for wind and tide favorable. However, at 12ft, this is strictly for experts. Beginners will get buried. This is the standout session of the whole outlook.
The days leading up to that are mostly a washout. From Tuesday the 8th right through to Monday the 14th, it’s a stretch of poor to marginal conditions. The wind is mostly cross-shore or cross-onshore, and the swell is short-period (7-8 seconds) and lumpy. The water is messy. You won’t want to paddle out.
After the big Tuesday the 15th, it drops off again. Wednesday the 16th is small and marginal, and from Thursday the 17th through Sunday the 22nd, it’s back to poor conditions with strong, onshore winds and lumpy, choppy waves. The swell is there, but the quality is gone.
So, to sum it up: Monday the 7th is a solid, albeit slightly choppy, session. The absolute standout is Tuesday the 15th for the big, expert-only swell. Other than that, it’s a long wait.

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.
