The Lowdown
Alright, let’s break it down. Over the next couple of weeks, there’s a bit of a mixed bag for Anzacs. The first few days are pretty rough with onshore winds and messy conditions, but things start to clean up after the weekend. The real standout looks like the first of September, with a glassy morning and a solid SW groundswell.
Right now, the water temperature is sitting about average for the time of year, nothing unusual.
Wednesday 19th and Thursday 20th – pretty poor. Wind is howling from the north and northwest, gusting up to 22 mph, and the wave quality is just not there. Swell is small too, around 1 ft to 3 ft, with moderate energy (250). Not worth paddling out.
Friday 21st – still cross-shore wind, but the swell picks up a bit to 3 ft–4 ft from the southwest, period around 15–16 seconds, so there’s some decent energy (654–861). Still, it’s messy with a cross-chop, so only marginal at best.
Saturday 22nd – swell jumps to 7 ft, with very strong energy (1958) and a 15-second period, but the wind is cross-shore and then cross-on. That’s big for the break, and with the wind on it, it’s going to be choppy and tough. Only for experienced surfers, and even then, conditions are marginal.
Sunday 23rd – slightly better. Swell drops to 5 ft–6 ft, still strong energy (1339–1599), and the afternoon goes light cross-on with a slight breeze. That’s the first hint of something rideable, but still not clean.
Monday 24th – a bit of a letdown. Morning has clean conditions with cross-off wind from the NNW, but the swell is only 4 ft and the energy is moderate (659). The afternoon goes choppy again.
Tuesday 25th – poor. Onshore wind and lumpy conditions.
Wednesday 26th – finally some improvement. Morning is clean with a light cross-off breeze, 4 ft SW swell, moderate energy (568). The afternoon gets even better: glassy conditions, cross-off wind, 4 ft swell, but only 349 energy. That’s a small window of clean, rideable waves.
Thursday 27th – wind picks up again, strong breeze from the NNW, and the swell is small and weak. Not good.
Friday 28th – big swell rolls in, 8 ft from the SW with a 16-second period, and very strong energy (4331). But the wind is onshore and strong from the south, making it lumpy and messy. That’s more of a kite-surfing day than a paddle-surfing day.
Saturday 29th – this is the first real bright spot. Morning is clear, light offshore from the SE, clean conditions, and a 5 ft SW swell with 14-second period and 976 energy. The forecast says “expect very good surf conditions.” This is the best of the run so far, with clean, well-shaped waves. The afternoon goes cross-shore but still rideable.
Sunday 30th – morning is clean again with cross-off wind, but the swell drops to 4 ft. Still a decent little session.
Monday 31st – morning looks promising with a 5 ft SW swell, 16-second period, strong energy (1147), and clean cross-off wind. That’s a solid groundswell with good shape. But the afternoon gets choppy again.
Tuesday 1st September – here’s the standout. Morning is glassy, offshore wind from the NNE, with a 5 ft SW swell, 15-second period, and 836 energy. The forecast says “expect very good surf conditions.” This is the pick of the whole outlook – clean, lined-up waves, perfect for a long session. The afternoon goes onshore, so make the most of the morning.
Wednesday 2nd – small and cross-shore, not much happening.
Thursday 3rd – now this is a real treat. Morning is glassy, with a 5 ft SW swell, 18-second period, and very strong energy (1344). That’s long-period groundswell – the kind that wraps around points and reefs beautifully. The forecast says “excellent surf conditions for experienced surfers.” With such a long period, the sets will be well-spaced and powerful, best at a point or reef break. For a beach break, it might break a bit too straight, but if you’re on it, it’s going to be an epic session.
So, to sum it up: the first week is mostly a write-off with wind and chop. The best windows are Saturday 29th morning, Monday 31st morning, and the real standout is Tuesday 1st September morning with glassy offshore winds and a solid SW groundswell. And keep an eye on Thursday 3rd September – that glassy, long-period groundswell is a rare one.

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.
