The Lowdown
G’day, Rusty here. Look, it’s a bit of a mixed bag for Anzacs over the next couple of weeks. We’ve got a solid long-period groundswell on the way, but the wind’s gonna be a real pest for a lot of it. The water’s sitting about 56°F, which is pretty much bang on average for this time of year, so no need for the thickest wetsuit just yet.
This first run of surf kicks off Monday afternoon. Swell’s 4ft from the southwest with a lovely 16-second period – that’s proper groundswell energy, good and pushy. The combined energy is 837, so moderate. Winds are light cross-off from the ESE, so it’ll be clean. It’s a bit marginal with the tide, but it’s a start.
Tuesday morning is where it gets good. Offshore wind from the NE at only 6 mph, 4ft southwest groundswell at 15 seconds, combined energy of 821. Surf’s gonna be clean and well-shaped. That’s one of the standouts for this first week.
Wednesday and Thursday are a write-off thanks to strong onshore and cross-shore winds. We’ve got a few days of slop.
Friday the 21st sees the swell bump up again – 4ft from the WSW with a 15-second period, energy jumps to 1343, so moderate to strong. But the wind is cross from the NW at 16 mph, so it’s lumpy and marginal.
Now, the real standout for the whole forecast comes on Monday the 24th. Glassy conditions – wind from the WSW at just 3 mph – with a 4ft southwest swell, 14-second period, and combined energy of 626. The forecast says expect very good surf. That’s a session to pencil in.
Tuesday the 25th offers another glassy afternoon. No wind at all, 3ft southwest swell at 12 seconds, energy 366. Small but clean as a whistle.
We then hit a bit of a dry spell. Wednesday the 26th through to Sunday the 30th is mostly poor with strong, messy winds and onshore slop. The swell gets real big on Saturday the 30th – 7ft from the SSW at 16 seconds, energy of 2606 – but it’s cross-onshore and choppy. That size with that wind is more of a kite session.
The last real gem is Monday the 31st. A glassy morning with light easterly wind at 3 mph, 4ft southwest swell at 14 seconds, energy 1398. Excellent conditions for experienced surfers is what’s on the card. That’s the best of the whole run, and it’s still a week and a half away, so keep an eye on it.
Into the first of September – Tuesday morning brings clean offshore wind from the NNE at 9 mph, 4ft southwest groundswell at 17 seconds, energy 841. Lovely shaped waves, expect very good surf. That’s a solid finish to the outlook.
So, two true standouts: Monday the 24th for the glassy clean conditions, and Monday the 31st for the bigger, still glassy swell. Mark ‘em down.
Rusty.

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.
Anzacs is 44 km (27 miles) from Mornington. If you plan a holiday in Phillip Island, look for hotels and other accommodation in Mornington. Mornington has rooms for a wide range of budgets as well as car hire and transport links.
