The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for our region.
Right off the bat, the first few days are a write-off. We’re talking Wednesday the 19th through Friday the 21st – the wind is howling from the north and northwest, and the swell is getting chopped up. You’d be better off staying on the beach. The water temp is sitting at a pretty average 56°F for this time of year, so nothing crazy there.
The first real glimmer of hope comes on Sunday the 23rd. The afternoon at Anzacs is looking like a gem. The wind drops to glassy – zero wind – and we’ve got a solid 6ft swell from the southwest with a period of 15 seconds. That’s proper groundswell, packed with energy (1339 combined swell energy). The water will be clean, the waves will have some push, and it’s going to be a great session for experienced surfers. This is the standout of the whole forecast period. The only downside is that it’s a very consistent spot, so expect a few other paddlers out there.
After that Sunday high, we’re back into a bit of a lull. Monday and Tuesday are marginal at best with cross-shore winds and messy conditions. The swell drops off, and the energy levels are low.
Now, looking further ahead into the second week, there’s something promising brewing for the very end of the month. On Monday the 31st of August, we’ve got light offshore winds from the north-northeast and a clean 2ft swell from the southwest, but with a very long period of 19 seconds. That’s a classic groundswell. The energy is moderate (472 combined swell energy), but the wind will be perfect for lining up those waves at Anzacs. It’s a smaller day, but it’ll be clean.
The absolute best of the long-range stuff is on Tuesday the 1st of September. Morning session: light offshore wind from the north-northeast, and a 5ft swell from the southwest with a 15-second period. The energy is climbing (972 combined swell energy), and the forecast is for “very good surf conditions.” This is the one to circle on the calendar. Get ready for some clean, powerful waves.
Finally, Wednesday the 2nd of September morning has glassy conditions again with a 4ft southwest swell, but it’s a smaller, cleaner day to finish off the run.
So, to sum it up: the first few days are a bust. The big winner is Sunday the 23rd afternoon – glassy, solid, and powerful. The backup is the Tuesday the 1st of September morning. Everything else is a bit of a gamble or just small.
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.
