The Lowdown
Alright, let’s talk in feet and miles an hour for those who don’t do metric.
The swell window is open, but the wind is gonna be the deciding factor. The first proper session fires up on Sunday morning.
Peak Rock is a reef setup, soaked by SW swells. Water temp is about normal for this time of year. Sunday the 23rd, we’ve got a solid 8ft SW groundswell with a 14-second period. That’s a lot of juice—combined energy of 2503, which means strong wave energy. The wind is a light offshore from the NNW, so the surface will be clean. This is the pick of the bunch early on. It’s for intermediate-to-expert crew only at that size. The long period means there’ll be a break between sets, making the paddle out easier. Crowds can show up here sometimes, so be ready.
Sunday afternoon cleans up with a glassy WNW breeze, dropping to 6ft, but still packing 1793 energy. It’s still top-notch.
Monday the 24th, the swell drops to 5ft, but it’s clean with a moderate offshore N wind at 15 mph. Energy drops to 874. Monday afternoon stays clean with a NNW wind, 5ft at 13 seconds. A decent backup session.
Tuesday the 25th is a mess. Light rain, cross-shore winds from the ENE and then WSW at 9 mph, making the surface bumpy. Swell is 6ft and 5ft, with energy around 1000, but the chop kills it. This is a kite-surfing day if you’ve got it.
Wednesday the 26th is similar—cross-shore WSW winds at 15 mph, with a 7ft swell in the afternoon. Energy jumps to 2085, but the wind is ugly. Thursday the 27th is small and clean—4ft with a light offshore NW wind. A fun little morning wave.
Friday the 28th gets serious again. A 8ft, 18-second SW groundswell hits in the morning with a cross-offshore NW breeze. The energy is massive at 3379, and it’s clean. That 18-second period is very long, so the waves will be grinding and perfect for a reef. The afternoon gets an onshore south wind and ruins it. This Friday morning is a major standout.
Saturday the 29th is cross-shore and lumpy. Sunday the 30th has a cleaner morning with a cross-offshore WNW breeze, 6ft, then the afternoon blows up to 8ft at 16 seconds with a massive energy reading of 4462. Wind is cross-shore, so a bit messy, but the power is unreal.
Monday the 31st is the next big one. Morning sees a 8ft, 15-second SW swell with a clean offshore NW wind at 12 mph. Energy is 2502. Monday afternoon is even better with 7ft at 16 seconds and a light WNW cross-offshore breeze. Clean and heavy.
September 1st brings strong 25 mph winds—offshore from the NW in the morning—6ft at 16 seconds, but it’s a fight to paddle into. The afternoon has the same wind issue with a 8ft swell. September 2nd is more strong offshore wind, making it tough. September 3rd gets dangerous. The afternoon has a 13ft, 12-second swell from the WSW with 8250 energy. That’s insane power. The wind is cross-offshore at 25 mph, so it’s clean but massive. Expert only.
September 4th starts with an 12ft, 17-second SW swell, energy at 7345. Cross-offshore wind. Huge and only for the brave.
September 5th is the last solid day. A 7ft, 14-second SW swell with a moderate offshore NNW breeze. Clean and a good size for advanced surfers. September 6th drops off hard, and September 7th is just 5ft with a fresh offshore, nothing special.
The long-range stuff around September 3rd and 4th is a big, promising but less certain swell—it looks huge.
It’s a patchy run. Lock in Sunday the 23rd morning and Friday the 28th morning. After that, pick your days clean.
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.
