The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks at Peak Rock.
We’re getting a solid run of SW groundswell, with some serious energy on the way. The water’s sitting at 56° right now, which is pretty normal for this time of year. The early part of the week has some nice, manageable swell, but the real juice comes later.
For the standout session, I’m looking at Monday morning, 31 August. You’ve got a clean 7ft SW swell at 14 seconds – that’s proper groundswell, and with a light W wind 6 mph it’s cross-offshore. That’s gonna be glassy, lined-up, and just beautiful for an intermediate surfer. The energy is pumping with a reading of 1828, so there’s plenty of push. It’s a reef break that’s fairly consistent, but expect company – it does get crowded sometimes.
The rest of the first week holds plenty of options, but nothing quite as clean as that Monday morning. Swell sticks around in the 6ft to 7ft range, with that same long-period SW groundswell. Winds are mostly cross-off or offshore, keeping things tidy, though the 28 mph N offshore wind on Tuesday morning, 1 September, will make paddling out a real mission – that one’s for the fit lads only.
Then we hit a bit of a tricky patch. Around 5 September (Saturday), the swell jumps up to 13ft with winds howling at 34 mph from the NW. That’s a kite-surfing setup, not really for paddle surfing. That big, lumpy cross-off wind and heavy swell will be messy and dangerous for most. That stretch is gonna be a write-off for a couple of days.
After that, things settle. Sunday afternoon, 6 September, looks magic – glassy conditions, 6ft SW groundswell at 13 seconds, no wind. That’s a sneaky good session if the swell holds shape. Then from the 8th onwards, the energy ramps up big time. We’re talking 7ft to 15ft SW swell, with periods reaching 19 seconds. That’s very long-period groundswell, which can get a bit straight at some beach breaks, but at Peak Rock it’ll draw some nice lines.
The real highlight of the second week is shaping up for Thursday morning, 10 September. You’ve got 12ft of SW swell at 16 seconds, glassy conditions with a light SSW breeze, and the combined energy is a massive 6234. That’s a powerful, clean groundswell. This is for experienced surfers only – over 8ft, it’s expert territory. The swell direction is right on the money for this spot, and the period is prime for a reef break like this. That’s the one to circle on the calendar.
After that, we’ve got consistent 7ft to 10ft swell right through to the 14th, with clean windows on the 11th and 13th mornings. The 13th is another monster with 10ft SW at 19 seconds – that’s a very long period groundswell, and with light cross-offshore winds, that’ll be a special session for the strong paddlers.
Overall, there’s plenty to get excited about, with two real standouts: the clean, fun Monday morning on the 31st, and the big, glassy groundswell on Thursday the 10th. The middle of the first week and the 5th are washouts, but the rest has good quality swell.
Stay stoked,
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.
