The Lowdown
Right off the bat, Tuesday morning’s looking like the pick of the first week. We’ve got a clean 4ft SW swell rolling in at Anzacs, with a light offshore breeze keeping it glassy. The water’s sitting at 56°, which is pretty much spot on for this time of year—nothing wild there. The energy’s moderate, sitting at 821, but it’s the quality that counts. This is the one to get out for.
The rest of Tuesday afternoon fades into a bit of a cross-shore chop, and then we hit a wall. Wednesday through Friday are pretty much a write-off. The wind goes onshore or cross-shore, the swell drops, and the surf gets messy. There’s a pulse of energy building through Friday, but it’s still not worth paddling out for.
Then Saturday the 22nd, things get interesting, and not in a good way. The swell jumps up to 8ft, but it’s a jumbled mess with strong cross-onshore winds. By the afternoon, it’s a full 10ft onshore slop. This is more of a kite-surfing day than a paddle-surfing day. Sunday and Monday settle down a bit, but the wind keeps it from being clean.
The following Tuesday and Wednesday, the 25th and 26th, are small and clean-ish, but just not enough push. We’re talking knee-to-waist high dribble. The wind is light, but there’s no real power behind it.
Now, here’s the standout for the back half of this window. Monday the 31st of August is looking proper. The wind drops to nothing, it’s glassy, and there’s a clean 4ft SW swell with a nice 16-second period. This is a long-period groundswell, so it’ll have some push and shape to it. Crowds could be a factor, but on a day like this, it’s worth the company. That’s a true gem.
Following that, the 2nd of September, mid-week, has another shot—a clean 4ft SW swell, some glassy calm conditions in the afternoon, and light ENE winds in the morning. That string of days around the end of August into the first days of September is the real deal. Tuesday the 1st is more marginal with onshore winds, but Wednesday the 2nd brings it back.
So, short version: get out Tuesday morning for a quick one, and then mark your calendar for the 31st of August. That’s the one that’s got my attention. The long-range stuff is always a bit less certain, but the potential is there. Until next time, this is Rusty, signing off.

Information about the Anzacs Surf forecast
The above surf forecast table for Anzacs provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Anzacs can be found by selecting the local surf guide option on the grey menu. Our Anzacs 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 (Anzacs) 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 Anzacs 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.
