The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Anzacs.
We’ve got a proper run of solid, long-period SW groundswell heading our way over the next couple of weeks. The water temp is sitting at 56°F, which is about bang on average for this time of year, so nothing unusual there. The first few days are a bit of a write-off thanks to strong winds, but once that cleans up, there’s some serious potential.
The first real chance to get wet is Monday afternoon, August 31st. The swell is a clean 5ft from the SW with a long 15-second period, and the combined energy is a solid 1261 (moderate). The wind is light and offshore from the SSW, which is a major positive. It’s a start, but the shape isn’t firing on all cylinders with the tide. Still, a surfable option.
Tuesday the 1st and Wednesday the 2nd are a no-go. A strong NNW wind blows through, making it messy and cross-off, then it swings cross-on, chopping things up. The swell bumps up to 6ft but the quality is poor.
Thursday the 3rd is a washout. A big 10ft SW swell hits, but the wind is howling onshore from the W at 25 mph. The combined energy is monstrous (3105), but it’s a complete mess. Not for paddling.
Friday the 4th sees the swell drop to 8ft, but the wind is still a strong cross-off from the NNW at 19 mph. The energy is huge (2888), but it’s big and on the edge. Better for the experienced crew.
Saturday the 5th is a full-blown storm. 12ft swells, 4334 energy, and a near gale cross-on. Stay home.
Now, Sunday the 6th is where it starts to get interesting. The swell eases to 8ft from the SW, period still 16 seconds, and the wind swings light cross-off from the NNW. The energy is still high (3482), and it’s clean. This is a proper big-wave day for experienced surfers. The crowd factor is “sometimes,” so expect company.
The standout, and I mean the real standout, is Wednesday the 9th and Thursday the 10th. This is the best of the lot. On Wednesday morning, the swell is a solid 8ft from the SW with a 17-second period, and the wind is dead calm – glassy. The combined energy is 3125 (strong). The guidance says “excellent surf conditions for experienced surfers,” and I’m telling you, that’s a rare combination. Thursday morning is even better, with a 7ft, 19-second period SW groundswell, glassy conditions, and 3662 energy. That’s a very long-period groundswell, which will be epic at a point or reef, but at a beach break it might throw some straight lines. Still, for the experienced surfer, that’s the session to circle.
The following week (11th to 15th September) sees the swell drop back down. The 11th and 12th are clean but smaller, with 6ft and 4ft swells. The 13th and 14th are choppy and cross-on. Tuesday the 15th morning offers a final glimmer with 5ft, a 15-second period, and light offshore wind – clean and fun for the smaller-wave crew.
So, to wrap it up: the real blue-ribbon days are Wednesday the 9th and Thursday the 10th of September. Glassy, powerful, long-period SW groundswell. You’ll need to be on your game, and you’ll be sharing the water, but that’s the kind of day you live for.
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.
