The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s heading our way. We’ve got a solid run of South West groundswell on the cards for Peak Rock, and it’s a reef break that likes that direction. Water temp is sitting at 57°F right now, which is about average for this time of year, so no surprises there.
The immediate picture is a bit average. Sunday morning (30th August) kicks off with 6ft of SW swell, but the wind is a bit messy and it’s marginal. The combined energy is moderate (1217). Not the one to get excited about.
Monday 31st August is when things start to get tasty. Morning sees 7ft from the SW with a clean cross-off breeze, and the energy jumps up (1828). Then Monday afternoon is the absolute standout: the swell drops a touch to 7ft, but the wind goes glassy from the SSW, and the energy is pumping (1982). That’s clean, lined-up reef waves for the experienced crew. This is your best window early on.
Tuesday 1st September flips dramatically. The swell is still there, but a howling 25 mph offshore wind from the north makes it a battle to paddle into. The waves are clean but only for the hardcore, and the forecast calls it marginal. It’s a no from me.
The swell builds again through Wednesday and Thursday (2nd-3rd September), hitting 8ft and then 10ft. The wind is strong and cross or cross-off, which keeps it clean but the period is shorter (13 seconds), so it’s less refined. The energy is strong (2713 then 5134), but Thursday afternoon gets lumpy and messy with the cross-shore wind. That’s a miss.
Friday 4th September is another big winner. The swell is a solid 10ft from the SW with a very long 16-second period. The wind is offshore and moderate from the north-northwest, keeping it clean. The energy is massive (5068 in the morning). This is for experienced surfers only – it’s powerful, hollow, and demanding. But if you’ve got the skills, this is the session to aim for.
From there, the swell slowly fades through the first week of September, staying around 5ft to 7ft, with variable winds. The middle of the second week, around 11th and 12th September, looks promising again. Friday morning (11th) has a 5ft swell with a very long 20-second period, clean cross-off breeze, and excellent conditions. Then Saturday 12th morning has 6ft from the SW with a gentle offshore, and Saturday afternoon goes glassy with 6ft and 16-second period. That’s a beautiful, clean weekend window.
The forecast confidence drops for the second week, but those late dates are worth keeping an eye on. The run of swell is consistent, and the reef handles the long period well, so the shape should be good.
Overall, the two standouts are Monday afternoon 31st August and Friday 4th September. Monday is the cleaner, more accessible glassy session for intermediates, and Friday is the big, powerful groundswell day for the experts.

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.
