The Lowdown
G’day, Rusty here.
Let’s look at what’s brewing for Peak Rock over the next couple of weeks. Starts off a bit quiet, but there’s some real juice later if you wait it out.
The water’s running at 13.2°, which is about 0.7° warmer than average for this time of year – nothing crazy, just a touch on the comfortable side.
Tuesday 18th August: A bit of a start. Tuesday morning brings a 3.9ft SW groundswell with a long 14-second period, and moderate wave energy (962). A gentle cross-off breeze from the NE at 9 mph keeps it clean. Good for intermediate surfers, but don’t think you’ll have it to yourself – the crowds pop up sometimes. The afternoon glass off a bit but the energy fades.
Wednesday 19th: A day to skip. Strong winds from the N at 25 mph thrash the place all day with small 2.3-2.6ft SW swell. Wednesday afternoon sees offshore wind but it’s blowing a gale – you’ll struggle to even get out. Save your energy.
Thursday 20th: Thursday morning offers a chance. A 3.9ft WSW swell with a 13-second period and moderate energy (777) under a light offshore NW breeze at 16 mph. It’s clean, but the wind is moderate, so not pristine. The afternoon gets a bit lumpy with stronger cross-off winds.
Friday 21st: Swell builds. Friday morning you’ve got 5.2ft from the WSW with a 12-second period and solid wave energy (1365). A moderate cross-off from the NW at 12 mph keeps it clean. Good session for those with some experience. The afternoon backs off a little.
Saturday 22nd: Now we’re talking. Saturday morning serves up a 9.8ft SW groundswell with a very long 16-second period and strong wave energy (4603). That’s serious size – over 8ft, so experts only. The wind is a moderate cross-off from the WNW at 16 mph, keeping it clean. The afternoon gets even bigger with the same 9.8ft swell, but the wind swings to a moderate cross-shore from the SW, stirring up some chop. This is the standout for the experienced crew, but that long period might make it wall up a bit at the reef. If you’re solid, get in there. Expect crowds.
Sunday 23rd: Swell holds but drops a touch. Sunday morning has 6.9ft from the SW, 14-second period, and strong energy (2495). A light offshore from the NW at 9 mph makes it clean and inviting. The afternoon is similar with 7.2ft swell and a light breeze. Still big, still for experienced surfers.
Monday 24th into Tuesday 25th: Swell settles into the 3.6-5.2ft range with long periods and gentle winds – offshore on Tuesday morning. Clean, manageable, good for intermediates. A nice run.
Wednesday 26th to Thursday 27th: The wind turns nasty again. Strong to fresh gales from the N and WNW make the 3.6-7.5ft swell messy. Thursday sees a 7.5ft WSW swell with a short 8-second period and fresh cross-off winds – it’s a sloppy, choppy mess. More of a kite-surfing day than a paddler’s dream.
Friday 28th: Friday morning offers a glimmer with a 6.6ft SW swell and a strong offshore NW wind at 28 mph. It’s clean, but that wind is howling – hard work to paddle into. The afternoon gets even stronger. Only for the die-hards.
Saturday 29th and Sunday 30th: A bit of a dud. Onshore winds from the S and SSE, with a long-period 3.6-3.9ft swell, but the wind is onshore or cross-onshore, making it lumpy and messy.
Monday 31st August: The real sleeper. Monday morning is glassy – 3 mph from the SSE, dead calm. You’ve got a 5.2ft SW groundswell with a very long 16-second period and strong energy (1535). This window is excellent for experienced surfers. Clean, glassy, and good size. This is the other standout if you can wait. The afternoon gets a gentle cross-onshore, so hit the morning session.
Tuesday 1st September: Still surfable with 4.6ft SW swell, long 16-second period, but a light cross-onshore wind makes it a bit choppy. Not the best.
Wednesday 2nd September: The last day, Wednesday morning has a 5.6ft SW swell with a 17-second period and strong energy (1703). A gentle cross-shore from the ENE at 9 mph gives it a slight chop

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.
