The Lowdown
Alright folks, Rusty here. Let’s break it down.
We’ve got just one spot in the mix for this 16-day stretch: Peak Rock. It’s a reef set-up, so it’s got that nice, defined shape when the swell lines up. The water temp is about average for this time of year, so nothing wild there.
The forecast kicks off on Saturday the 22nd, but it’s a bit of a rough start. The swell is already building with a solid 7ft of SW groundswell and a juicy 15-second period, producing a ton of energy (3277). But the wind is howling from the west at 30 km/h, blowing cross-offshore. It’s clean, but that wind is strong, and the report says “marginal” – it’s a battle. Saturday afternoon the swell jumps to 10ft with a 14-second period, and the energy goes through the roof (6998), but the wind swings to a cross-shore chop. That’s big, over 8ft, so it’s expert territory only. For a kite surfer, that afternoon setup would be a blast, but for paddling, it’s a handful.
Now, Sunday the 23rd is where it gets proper. Morning brings a 7ft SW swell (14-second period, 2395 energy) and a clean, offshore wind from the NNW at 15 km/h. The report says "excellent" for experienced surfers. That’s a standout. The afternoon goes glassy with a light NW breeze, swell dropping to 6ft but still holding that 13-second period. That’s your window for Peak Rock.
Monday the 24th is still decent but a step down. The morning has a 5ft SW swell (14 seconds, 874 energy) but the wind is a fresh 30 km/h offshore. It’s clean, but a bit of a blow. The afternoon cleans up nicely with a gentle offshore breeze, same swell size, and the report says "very good" conditions.
Then we hit a rough patch. From Tuesday the 25th through to Thursday the 27th morning, it’s a mix of cross-on winds and onshore slop. The swell is there, but it’s choppy and messy. Not worth paddling out for.
Thursday the 27th afternoon is a little gem. The swell is only 4ft, but it’s a 14-second SW groundswell, and the wind drops to dead glassy calm. The energy is low (795), but that’s clean, lined-up reef waves. A real sneaky session.
Friday the 28th morning is another standout. The swell jumps back up to 7ft, swinging to a WSW direction, with a very long 17-second period. That’s serious groundswell, and the energy is pumping (3023). The wind is a moderate offshore from the NNW. The report says "excellent" for experienced surfers. That long period will groom the reef perfectly, but keep in mind at a beach break it might be too straight. At Peak Rock, it’s a dream.
The weekend of the 29th and 30th is a write-off. The wind is onshore or cross-shore, and the conditions are poor, even with a 10ft swell on Sunday afternoon. Don’t bother.
Monday the 31st is a special one. The morning is completely glassy, with a 7ft SW swell carrying a 16-second period (2475 energy). The report says "excellent" for experienced surfers. That’s your best bet for the whole forecast. Clean, powerful, and empty feeling.
The first week of September (1st to 3rd) is a mixed bag. Tuesday the 1st has an 8ft swell but strong cross-off wind, then onshore slop. But Thursday the 3rd is excellent: morning has a 5ft SW swell with a clean offshore wind, and the afternoon brings a 7ft swell with the same offshore breeze. Both are labelled "excellent" or "very good."
The final weekend, the 5th and 6th of September, looks promising. Saturday the 5th has a 6ft SW swell with a light offshore wind, going glassy in the afternoon. Sunday the 6th morning has a 5ft SW swell, 15-second period, and a clean moderate offshore wind.
The Verdict: The absolute best on offer is Monday the 31st of August at Peak Rock. Glassy, 7ft of SW groundswell at 16 seconds. That’s a quality session. The second best is Sunday the 23rd of August morning, with that clean offshore wind and 7ft SW swell. The Friday the 28th of August morning is also a banger for the very long-period crew.

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.
