The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up for Peak Rock over the next couple of weeks.
We’ve got a solid run of surf on the way, but it’s not all going to be clean. The real standout looks to be the very start, with a powerful, long-period groundswell pushing in. The water temp is sitting at 56°F, which is pretty much bang on average for this time of year, so nothing unusual there.
Monday the 10th is your call-to-action. Morning brings a 7ft SW groundswell with a very long 19 second period, and it’s packing a huge 2974 combined energy. That’s a lot of water moving. The wind is a fresh offshore from the NNW, so the face should be clean and lined up. This is serious, powerful stuff, and at that size with that period, it’s going to be one for the experienced crew only. The crowd factor here is “sometimes” so you might have some company, but the quality should make it worth it. The afternoon gets messy with a cross-on shore, so the morning is the window.
Tuesday the 11th drops off a touch in size to 5ft, but the period stays at 14 seconds. The wind is offshore again in the morning, so it’ll be clean and rideable, just not the same punch as Monday. Wednesday the 12th sees the swell bumping back up to 8ft with a 16 second period, and the wind turns cross-off. The energy is up in the 3000-4000 range, so there’s plenty of grunt, but the cross-off angle might make it a bit tricky to find the perfect peak. It’s still good, solid surf, but not quite the perfection of Monday morning.
Thursday the 13th through Saturday the 15th holds at 8ft to 10ft with that long 16-17 second period, but the wind becomes a problem. Cross-off and cross-on breezes will put a chop on the surface, making it lumpy and less inviting. The energy is still massive, hitting 6460 on Friday morning, but the quality just isn’t there for a paddle surfer. At this size and with these winds, this stretch actually looks more interesting for the kite crew than for us.
We then hit a lull. From Sunday the 16th afternoon right through to Tuesday the 20th, the swell drops below 5ft, and the wind stays tricky. It’s a quiet patch where you’d be scratching for a wave.
Then things get interesting again on Tuesday the 18th. We get a 5ft SW swell with a 15 second period and a light cross-off wind in the morning. But the real gem is Tuesday afternoon: glassy conditions with a 4ft swell. That’s a beautiful window for a longboard or a funboard, just you and the ocean.
The end of the run, around the 23rd and 24th, looks promising but is a long way out. The 23rd is showing a big 10ft SW swell with 17 second period, but with a strong 28 mph cross-off wind it’ll be wild. The 24th, however, has a 6ft SW swell with glassy conditions in the morning. That one has the potential to be a real gem, but it’s over two weeks away, so we’ll have to keep an eye on it.
Overall, the clear winner is Monday the 10th morning. If you’re an expert, that’s your session.
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.
