The Lowdown
Alright, let’s get into it. The next couple of weeks here at Peak Rock (reef break) start off with a bit of a tease. We’ve got a small, long-period groundswell building, but the real juice doesn’t start kicking in until the end of the first week and into the second. The water temp is sitting at 13°, which is pretty much normal for this time of year, so no surprises there.
On Thursday the 20th, we’ve got a tiny 2ft swell from the SW with a 18-second period. That’s a very long period for such a small wave – it’ll be super clean with that NNW offshore wind, but honestly, it’s barely a ripple. The combined energy is only 315 (weak), so it’s a paddle-out more than a surf session. The afternoon goes cross-off and drops the score.
Friday the 21st sees a jump to 4ft in the morning and 5ft in the afternoon, both from the WSW. The period drops a bit (14-15 seconds), but the energy starts to roar – 1124 (moderate) in the morning, then 1585 (still moderate) in the arvo. Winds are cross-off, so shape should be okay, but the conditions are described as marginal, likely due to tide. This is for intermediate surfers, and it’s getting more interesting.
Now, Saturday the 22nd is where it gets serious. The morning bump is 8ft from the SW with a 15-second period. The combined energy is 2955 – that’s strong. But here’s the catch: the morning wind is cross-off from the WNW, which helps clean it up. The afternoon jumps to 10ft (WSW, 15 secs) with a massive energy score of 6424 (very strong), but the wind swings cross-shore, bringing some chop. This is expert territory – over 8ft. Unless you’re a seasoned charger, sit this one out.
Sunday the 23rd is the first true standout. Morning sees 7ft (SW, 14 secs) and cross-off winds, energy at 2369 (strong). But the afternoon is the gem: the swell drops to 6ft, but the wind goes near glassy – just 3 mph from the NW, cross-off, with the combined energy still strong at 1753. The report calls it “excellent conditions for experienced surfers.” This is the best on offer for the entire first week. Clean, powerful, and not too crazy.
Monday the 24th has a fresh offshore blow (22 mph from the NNW) which will groom 5ft, 14-second SW swell – energy 904 (moderate). It’ll be clean, but that wind is strong enough to make paddling a struggle. Tuesday and Wednesday slip back into cross-on swill, with weaker conditions and smaller swell.
Now, for the second week, we’ve got a real late bloomer. Thursday the 27th afternoon is a treat: 4ft SW swell, 11-second period, light NNW offshore at 3 mph – glassy conditions, combined energy of 930 (moderate). Very clean.
But the clear standout of the entire 16-day window is Friday the 28th morning. We get 7ft from the SW, a 17-second period, combined energy of 2953 (strong), and light NNE wind – clean, cross-off. The report says “excellent conditions for experienced surfers.” This is a long-period groundswell hitting that reef at Peak Rock, and it’s the kind of pulse that gets the heart going. The wind is light and favourable, so the shape should be epic. Crowds are possible at this spot, so get in early.
From there, the swell backs off slowly. Saturday the 29th stays clean but smaller (5ft), and the 30th gets blown out by a strong 28 mph offshore – that’s too much wind, even if it’s offshore. The 31st has potential in the afternoon with light winds and 4ft, 16-second swell, energy 1040 (moderate). The first few days of September fade to small, weak swell (2ft to 4ft) with poor wind. Thursday the 4th of September finishes the run with a small but clean 4ft, 14-second swell and gentle offshore – surfable, but nothing to write home about.
Overall, there’s a big gap of marginal days in the middle, so don’t expect consistent action. The best two windows are Sunday the 23rd afternoon and Friday the 28th morning. Mark those dates.

Information about the Peak Rock Surf forecast
The above surf forecast table for Peak Rock provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Peak Rock can be found by selecting the local surf guide option on the grey menu. Our Peak Rock 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 (Peak Rock) 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 Peak Rock 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.
Peak Rock is 25 km (16 miles) from Mornington. If you plan a holiday in Mornington Peninsula, 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.
