The Lowdown
G’day, Rusty here. Look, this forecast is a rough one, plain and simple. We’ve got a lot of ocean energy coming through, but most of it is hitting us from the wrong angle and getting torn up by the wind. There’s a big dry spell at the start, so don’t rush out. The first few days are a total loss, and it’s not until mid-next week that we see anything with a pulse.
The first real chance comes on Thursday, September 3rd. Swell is 8ft from the NE, period is 8 seconds, and the energy is moderate. The wind is offshore, a cross-off from the NNE at 19 mph, so it’s clean. It’s not perfect—there’s a bit of lump—but it’s the first rideable window. Friday the 4th gets messy again, with onshore wind and rain, so skip it.
Your best bet is Saturday morning, September 5th. We’ve got 8ft of SSE swell with a 10-second period, and the energy is strong. The wind is light from the E at 6 mph, but it’s still cross-onshore, so it’s not glass clean. It’s the only day that comes close to being good, but it’s still a marginal call for an intermediate. Water temps are 69°, which is pretty normal for this time of year.
Then the ocean gets angry. Sunday the 6th brings 13ft of S swell, but it’s blown out by a near gale. Monday the 7th is even bigger, with 15ft waves and a 13-second period, but the wind is howling onshore. That’s not surfing, that’s a washing machine. Forget it. This beach with that much swell and onshore wind is a kite surfer’s dream, not a surfer’s.
Tuesday the 8th might have the wind and tide aligned, but the swell is too big for the break. It’s a no-go.
After that, it all fades. The second week is small, weak, and mostly chopped up. There’s nothing worth getting out of bed for. The swell drops, the energy drains, and it’s just not happening.
So, the only real standout is Saturday morning, September 5th, and even then, it’s an inconsistent, so-so session. Be patient, pick your moments, and don’t expect much. This is a week to watch the ocean, not fight it.
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.
