The Lowdown
G’day, I’m Rusty. Let’s break down what’s coming for Peak Rock over the next 16 days.
There’s a slow start – Sunday the 9th has waves but poor conditions and cross-off wind. Wait until Monday the 10th of August for the real deal. That morning delivers a clean offshore NNW breeze at 19 mph with a solid 6 ft swell from the SW, a very long 19-second period, and strong wave energy (2759). This reef loves long-period groundswell, so expect well-shaped, powerful waves. Crowds are possible – the spot can get busy. Swell direction matches the optimum for the break. Water temp sits around 56°F, about normal for this time of year, so you’ll be in a wetsuit.
After that, Tuesday the 11th afternoon has 6 ft with offshore wind, and Wednesday the 12th sees 8 ft with cleaner conditions. The next big call is Thursday the 13th afternoon – 8 ft, 15-second period, huge energy (2857), and a light offshore breeze. That’s expert territory right there.
The second week has some beauties. Monday the 17th morning: 5 ft, light N wind, clean. Tuesday the 18th morning: 4 ft, offshore N breeze, clean. Wednesday the 19th afternoon: offshore NNW wind with clean 4 ft surf.
The long-range standout is Sunday the 23rd of August. Glassy conditions, light W air at 3 mph, 6 ft of SW groundswell with a 17-second period and massive energy (2809). This is excellent surf for experienced hands. Monday the 24th morning is also excellent: 7 ft, cross-off wind, clean.
There are a few quiet days in the second week, but plenty of clean sessions to chase.
Rusty.

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.
