The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a solid 16-day window with only one break to talk about, so let’s dig into what’s coming.
The overall picture is pretty active, with a lot of swell on the way, but we’ve got to work around a few rough patches. The first real opportunity is this Friday afternoon, but it’s a bit of a tease – the swell is there at 4ft from the SW, but with a cross-offshore wind and a fair bit of energy (1123) it’s marginal. Not worth getting wet for.
Saturday the 22nd sees the swell jump up to 7ft and then 12ft, but the wind is cranking from the SW and that’s going to chop things up. The 12ft on Saturday afternoon is a lot of power (7310), but with cross-shore winds and lumpy conditions, it’s only for the hardcore.
Now, Sunday the 23rd is where it starts to get interesting. The morning has a clean 8ft SW swell with a light offshore breeze from the NW. That’s going to be good, clean surf for experienced surfers. But the real standout is Sunday afternoon. We’re looking at 7ft from the SW, glassy conditions with a light WNW wind, and the water temp is 56°F, which is about normal for this time of year. That’s the best session of the first week, no doubt.
The weekdays from Monday the 24th to Wednesday the 26th are a mixed bag. The mornings are mostly clean with offshore winds, but the swell is a bit all over the place. The surf quality is variable, and the afternoons get messy. Then we get a bit of a lull on Thursday the 27th, with only 3ft to 4ft, but it’s glassy in the afternoon, so it’s a nice little clean-up set.
Friday the 28th is another big one. A 8ft swell with a 17-second period, that’s a groundswell. The wind is offshore from the NNW, so it’s clean. This is a different beast – long period, lots of energy. For a reef break like Peak Rock, that’s a good thing. The waves will have shape and power. Saturday the 29th looks blown out.
The second week gets interesting again. Sunday the 30th has a 6ft SW swell with a NW cross-offshore wind in the morning – clean lines. Then Monday the 31st and Tuesday the 1st of September offer up 8ft and 8ft swells with long 16-17 second periods. The wind is offshore or cross-off, so the surf will be powerful and clean. This is a run of good, solid days.
The best on offer, though, has to be Sunday the 23rd afternoon. The combination of a solid 7ft SW swell, glassy conditions, and a reef break that holds it well – that’s a dream session. The second standout is the whole run from Sunday the 30th through to Wednesday the 3rd of September. That’s a full week of solid, clean, long-period SW groundswell. Monday the 31st morning with the 8ft SW swell and 17-second period, offshore wind, is a close second. It’s going to be a classic.
One thing to keep in mind: Peak Rock is a reef break, so it’s not for beginners. Anything over 8ft is only for the experienced crew. The swell is from the SW, which is the optimum direction for this spot. Crowds are possible, especially on the good days.
Alright, that’s the picture. Get out there and get wet.
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.
