The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' over the next couple of weeks.
Right off the bat, we've got a bit of a flat spell. The first real chance of a surfable wave doesn't show up until Sunday the 23rd of August, and even then it's a marginal call. The week leading up to that is mostly a write-off with poor conditions and onshore winds, so you're not missing much.
The standout period, and the one I'd be circling on the calendar, kicks off around the 31st of August and runs into the first few days of September. On Monday the 31st, the wind goes glassy in the afternoon, with a clean 3ft swell from the SW. It's small, but that's the kind of silky smooth surface that makes a longboard or a funboard feel like a dream. The water temp is about 56°F, which is pretty normal for this time of year, so a decent wetsuit is still the go.
The real gem, though, looks to be the morning of Tuesday the 1st of September. We've got a 3ft SW groundswell, but with a very long period of 17 seconds. That's a heap of energy for a small wave, and combined with a light offshore breeze, it's gonna be clean and lined up. The combined swell energy is pumping at 776 (moderate), and with the offshore wind, Anzacs should be offering up some real quality. The only downside is that this spot can get crowded sometimes, so get in early.
Later in the window, on the afternoon of Wednesday the 2nd of September, the swell jumps up to 10ft from the WSW, but it's only a short 11-second period. It's still clean with a cross-offshore breeze, but at that size, it's strictly for the experienced crew. The energy is massive (2733), but it's a big, powerful wave that will be a handful.
The week after that gets messy again. By Friday the 4th and 5th of September, we're looking at a big, blown-out 12ft SW swell with strong onshore winds. That's a no-go for paddling, but if you're into kites, that's a different story.
So, to sum it up: wait for the glassy spells on the 31st, and then make sure you're out there for the morning of the 1st of September. That's your best bet.

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.
