The Lowdown
Alright, let’s get this straight. It's Rusty, and I’m looking at what we’ve got for Ansteys. There’s no surf worth paddling out for until late in the first week. None. Zilch. That first Monday, Tuesday, and most of Wednesday are just a write-off – big, messy, cross-onshore slop with strong winds. Not even worth looking at.
That first real chance comes on Thursday, August 13th in the morning. The swell drops back to 1.7m (that’s about 6ft) from the ESE with a 9-second period. The wind’s going light and cross-offshore, and they’re calling for clean conditions. It’s not huge, but it’s rideable and clean – a solid little window after all that chop. The wave energy is moderate, around 507.
Friday morning the 14th turns glassy. Flat calm wind from the ESE, 1.5m (roughly 5ft) of swell at 8 seconds. It’s small but clean, and the water temp is sitting at 22° (about 71°F), which is about average for this time of year. Nothing wild.
The real standout? Look at the Monday and Tuesday mornings – August 17th and 18th. We’ve got clean glassy conditions both mornings. Swell sits around 1.6m to 1.7m (5ft to 6ft) from the east, 10-second period. The wave energy is moderate (around 520 to 604). For Ansteys, that’s a proper session. The wind is flat and the water will be smooth. It’s the best you’re gonna see in this 16-day spread. But keep in mind, the swell direction is E, and this break works best with an E, so the direction is spot on. Crowds are possible here, so get in early.
After that, things get rough again. From the 19th onward, the wind cranks up, the swell gets wonky, and we’re back to poor conditions. There’s a bit of small glassy surf on Friday morning the 21st – 1.0m (3ft) from the E, but it’s weak. The rest of the second week is either blown out or too messy to call.
So, to sum it up: sit tight through the first few days, get excited for Thursday morning the 13th, and then absolutely be on it for Monday 17th and Tuesday 18th for the best clean waves. After that, it’s a waiting game. The swell energy later in the second week gets stronger but the winds kill it – that kind of setup looks better for kite surfing than paddle surfing.

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.
