The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s in store for Ansteys over the next couple of weeks.
Straight up, we’ve got a bit of a waiting game on our hands. The early part of the forecast is a write-off, honestly. The first recommendation doesn’t pop up until the morning of Wednesday the 13th of August, so we’re looking at a gap of a few days with no worthwhile surf. The big issue early on is a massive swell on Wednesday the 12th, with a combined energy of 1283, that’s just too much for this spot. It’s a messy, un-surfable situation.
But then, things clean up nicely. The standout of the entire forecast is the morning of Thursday the 13th of August. The wind goes glassy, dead calm, and we’ve got a solid 6ft swell from the ESE. The energy is strong, sitting at 576, and with that offshore wind, Ansteys is going to be clean, lined up, and absolutely worth the paddle out. This is the one to circle on the calendar for a morning session.
The following Friday morning, the 14th, still has some juice with a 4ft E swell, but the wind is a cross-offshore, so it won’t be as perfect as Thursday. The swell hangs around at a similar size into the weekend, but the wind swings onshore or cross-shore, making it pretty average, with a combined energy dropping off. From the 15th through the 19th, the conditions are largely poor with onshore winds and a bumpy surface. Not much to get excited about.
We get a second pulse of serious energy arriving on Sunday the 23rd of August. We’re looking at an 12ft S swell with a combined energy of 2299, but again, it’s forecast as too big for this break. The wind is also cross-shore, so unless you’re an expert looking for a challenge, it’s a pass. That big S groundswell has a period of 10 seconds, but the size and wind make it a messy proposition.
The last few days of the month, from the 24th to the 27th, are a mix of leftover S swell and onshore winds, creating more lumpy, choppy conditions than anything user-friendly. The energy eventually fades right out, with barely a ripple showing by the 27th. So, to sum it up: get on the Thursday morning session, and don’t hold your breath for the rest.
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.
