The Lowdown
Right, mates, Rusty here. Let’s have a look at what Peak Rock has in store over the next couple of weeks. It’s a bit of a mixed bag, but there are a few windows to get excited about.
The water’s sitting at about 55°F right now, which is pretty much what you’d expect for this time of year – nothing weird going on there.
We’ve got a bit of a slow start. The first decent chance isn’t until Tuesday the 18th in the morning. The swell’s dropped to a clean 4ft from the SW, and with a light cross-offshore wind, it’ll be tidy. The energy’s moderate at 967, so it’ll be just fun, small waves for the intermediate crew. Not a standout, but a nice way to get the week going.
The real standout, the one you want to circle on the calendar, is Friday the 21st. Morning session is looking prime. We’ve got a clean 4ft SW groundswell with a solid 16-second period and offshore winds from the NW. The energy jumps back up to 1304, meaning there’s some proper push in the water. That long period will make for lined-up, powerful waves peeling down the reef. It’s a bit much for beginners at over 5ft, but for the intermediate and above crew, it’s going to be incredible. Crowds can be a thing here sometimes, so get in early.
Tuesday the 22nd is a write-off. A near-gale whips up a massive, stormy 13ft+ swell – that’s big, nasty, and ugly. Leave the surfboard at home; if you’ve got a kite, maybe take a look. The energy is insane, hitting 4279 and then 7811, but it’s completely unsurfable.
Things settle down after that blow, but the following week stays big. The 25th and 26th have 10ft SW swells, but the wind is cross-onshore, making it choppy and messy. It’s a lot of water moving around with no shape. Not recommended.
There’s one more solid chance right at the end of the forecast. Friday the 28th morning – look out. A 5ft SW swell with a very long 18-second period, pure offshore wind from the N, and clean as a whistle. The energy is a strong 1418. This is the kind of groundswell that will wrap perfectly around the reef at Peak Rock. It’s over the 8ft mark? No, just at 5, but with that period and power, it’s solid and for experienced surfers only. It’s a long way out, so don’t lock it in just yet, but it has all the makings of a proper session.
Into the very end, the 30th has a tiny 2ft groundswell with a massive 21-second period. Clean and glassy, but it’s going to be barely breaking at this reef. More of a longboard grovel.

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.
