The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for Anzacs over the next couple of weeks.
Right off the bat, there is a bit of a lull. The first good session doesn't show up until the morning of Monday, August 17th. That morning, we've got a clean 4ft southwest swell with a nice long 14-second period pushing in. The wind is a light cross-off from the ENE at 6 mph, so the face should be tidy. Water temp is sitting at 56°, pretty much average for this time of year. The combined energy is moderate at 488. It’s a solid, quiet start to the week.
That Monday afternoon gets a bit dicey—cross-shore wind and chop creep in, so I’d be getting my fill in the morning.
Tuesday, August 18th, is where it picks up. The morning session is the standout of this first week. We’ve got a clean 4ft southwest groundswell, period bumped up to 15 seconds, and offshore wind from the NE at 9 mph. The combined energy is a healthy 821. This is very good surf for an intermediate crew. Get out there early before the wind swings SE and turns it cross-shore by the afternoon.
From Wednesday the 19th through to around Friday the 28th, it’s mostly a write-off. Strong winds, messy conditions, and a lot of cross-chop. There’s a pulse of bigger swell around the weekend of August 22nd with 6ft to 7ft southwest swell, but the wind is all wrong—cross and cross-onshore—making it a lumpy, blown-out mess. For the next week, it’s grim, with only one flicker of hope on the morning of August 27th when the swell drops to 3ft but the wind goes glassy. That Thursday afternoon is a treat: 3ft southwest groundswell with a 17-second period and glassy conditions. It’s small, but it’ll be clean and fun for a log or a fish.
Now, hold onto your board for the last few days of the month and into September. The real standout is Monday, August 31st. That morning we’re looking at a massive 10ft southwest groundswell, a very long 17-second period, and clean cross-off wind from the NNE at just 6 mph. The combined energy is a whopping 8292—this is serious, powerful surf. This is strictly for experts only; that size and period will be a freight train. Best suited for a point break or reef setup, as it could close out fast at a beach break. The crowds are likely here, but for good reason.
Also worth a mention is the morning of Saturday, August 29th: 10ft southwest swell, period 14 seconds, light cross-off NNW wind, and clean conditions. Combined energy of 3273. Excellent for experienced surfers, but it’s a day or two before the big Monday event.
For the remaining days, the wind stays a bit unpredictable, and the swell drops back, but that Monday the 31st is the one you circle on the calendar.

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.
