The Lowdown
G'day, Rusty here. Let’s have a look at what’s coming down the line for Anzacs.
Honestly, the next week or so is pretty ordinary. We’ve got a bit of swell, but the wind is all wrong for a decent wave. Tuesday the 18th has a 3ft SW swell with 14-second periods, giving moderate energy (398), but a light cross-breeze will keep it bumpy. Water temp is 56°, which is about normal for this time of year.
Wednesday the 19th and Thursday the 20th are write-offs – small swell with fresh cross-off and cross winds, poor conditions. We go through a long, flat, messy stretch. Friday the 21st is onshore and choppy, no good. By Saturday the 22nd, the swell jumps to 8ft from the WSW with strong energy (5271) – that’s a solid, powerful wave, but with moderate cross-shore wind and a period of 16 seconds, it’s going to be a lumpy mess. Sets will be long and powerful, but the wind is killing it. Only for the experienced, and even then, it’s not clean.
The real standouts, the only times it’s worth paddling out, come right at the end of the period. Sunday the 30th morning is the standout. You’ve got a clean 5ft SW swell with 14-second periods, decent energy (1441), and a light offshore from the N at only 6 mph. Glassy, clean conditions. This is the best combination of size, shape, and wind in the whole outlook. Anzacs is very consistent and exposed to the SW, so it’ll be working. The water temp is around 56°, normal for the time of year.
Then Monday the 31st morning and afternoon are also very good. The morning has a 4ft SW swell with 15-second periods, light offshore N wind at 6 mph, and clean surf (1066 energy). In the afternoon, it goes glassy with a light SW breeze, and the swell holds at 4ft with a very long 17-second period – that’s a classic groundswell that will wrap in nicely, though it might break a bit straight at a beach break, making the paddle out easier with longer lulls. That afternoon is a special window.
Into the first week of September, Tuesday the 1st morning has a clean 4ft SW swell with 15-second periods and a light offshore NNE breeze – another solid option. Wednesday the 2nd afternoon has a small 3ft SW swell but with a very long 19-second period (766 energy) and clean conditions – small but perfect for a log.
The long gap of poor or marginal surf from Tuesday the 18th through to Saturday the 29th is rough, but the end of the month and start of September deliver. Don’t waste your energy on the messy days – wait for those clear mornings and that glassy afternoon on the 31st. That’s where it’s at.
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.
