The Lowdown

Alright, let me tell you what’s coming down the line. To be straight with you, it’s a pretty frustrating stretch for the next couple of weeks. We’ve only got one spot in the game, Ansteys, and it’s not exactly firing. For the first few days, the wind and the wave quality are just not playing ball. We’re looking at a big blank run until we get a glimmer of something surfable.

We start off Tuesday the 18th and Wednesday the 19th with small, weak swell around 3ft from the east, but the wind is a mess – cross-onshore or cross, and gusty. The water is about average for this time of year. The combined wave energy is moderate at best (213), but the conditions are poor and lumpy. Not worth paddling out.

Thursday the 20th brings a jump in size with a 7ft southerly swell, but it’s short period (8 seconds) and the wind is fresh cross-onshore, making it lumpy and ugly. Combined energy hits 585, but it’s still poor quality. Not a good look.

Now, the first real chance we get is on Friday the 21st morning. We get a 4ft swell from the south with a very long period of 13 seconds. The wind turns cross-offshore from the northeast, keeping the surface clean. The combined energy is strong (622). This is the standout of the week. The only problem is Ansteys is inconsistent, and with that long period groundswell, it might break a bit straight at this beach setup. But if you’re an intermediate, this Friday morning is your best bet.

The next glimmer shows up on Sunday the 23rd. The swell builds to 8ft in the morning and 8ft in the afternoon from the south, with period stretching to 15 seconds – that’s very long period groundswell. The wind is light, so conditions are only fairly choppy. Combined energy is massive in the afternoon (3016). This is only for experts, as 8ft is too big for beginners. The long period also means it’ll be walled up at the beach, so if you know what you’re doing on a point or reef, you’d be better off elsewhere. But for the brave, it’s promising.

After that, the wind turns ugly again for most of the next week, with strong breezes and messy cross-chop. We do get a small window on Sunday the 30th afternoon. The swell drops to 4ft from the south-southeast with a glassy wind. The conditions finally look clean, and the score says it’s good. Combined energy is light (224), so it’s small, but the glassy surface makes it a sweet little session for a longboard or a funboard.

After that, we’re back into a run of poor surf with messy winds all the way into early September. The setup is more interesting for kite surfing than paddle surfing on the bigger, windier days.

Look, the forecast can change, so keep an eye on it. For now, Friday the 21st morning and Sunday the 30th afternoon are your best windows at Ansteys.

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.
