The Lowdown
Alright folks, Rusty here. Let’s break down what’s happenin’ at Peak Rock for the next couple of weeks. There’s a heap of ocean energy on the way, but we’ve gotta be smart about when we paddle out. Water temp is about average for this time of year, nothin’ wild.
Kickin’ off Tuesday the 1st of September, we’ve got a solid SW groundswell pushin’ in at about 6ft, with a super long 16-second period and heaps of energy (1568). A strong offshore N wind is keepin’ it clean, but the waves are a bit tough to paddle into. Not a beginner day, but you intermediates with some grit might snag a few.
By Wednesday the 2nd, the swell builds to 6 to 7ft from the SW, energy climbin’ to 2427. The wind goes cross-offshore and the conditions stay tidy, though the wave comment flags it as a bit marginal.
Thursday the 3rd gets gnarly. Swell jumps to 10 to 11 feet with the wind cross and cross-off, morning rain showers makin’ a mess of it. The afternoon cleans up a touch, but that’s expert-level size – over 8ft for sure. Energy peaks at 7807.
Friday the 4th is a real treat for the experienced crew. Solid 10ft SW swell, long 15-second intervals, and a fresh offshore NNW wind all day. Energy is massive at 4585. Clean, powerful, lined-up waves. If you can handle it, this is a standout.
Saturday the 5th is a monster: 13 to 15 feet from the WSW, with energy skyrocketin’ to 7261. The wind is a near gale cross-offshore – it’s clean, but this is pure big-wave country. Experts only. For everyone else, this looks more like a kitesurfing day.
The big highlight is Sunday the 6th. Morning delivers an excellent 10ft SW groundswell, 16-second period, moderate offshore NNW wind, and energy at 4957. This is the one to circle on the calendar: excellent surf for experienced surfers. It drops to about 8ft in the afternoon, still clean.
After that, Monday the 7th goes flat and onshore. The next pulse hits Tuesday the 8th with a massive 10 to 13 foot SW swell and an 18-second period (energy over 9200), but the cross-shore wind wrecks it with lumpy chop. Skip it.
Wednesday the 9th cleans up: 11 to 12 foot SW swell, 18-second period, moderate cross-off wind, energy at 7011. Another solid day for the big-wave crew.
Lookin’ ahead, Friday the 11th of September is another standout in the second week. Clear skies, light offshore wind, a steady 10ft SW swell with a 17-second period, and excellent conditions. Energy is 5561 and 4558. Promising, but it’s a ways off – keep watchin’ the forecasts.
From Saturday the 12th onward, the swell fades. A few decent 6 to 7 foot days early on, but by Sunday the 13th it’s on the decline, and Monday the 14th through the end is mostly poor, onshore, and lumpy. Not much worth paddlin’ for.
So here’s the bottom line: your best sessions are Sunday the 6th and Friday the 11th. Both have that magic combo of size, clean offshore wind, and excellent conditions. Peak Rock is a reef that needs the right tide, but when it’s on, it’s on.
Stay sharp, and don’t miss that Sunday morning.
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.
