The Lowdown
Alright, listen up. The last few days have been a total dirge, but there's light at the end of the tunnel. You just gotta be smart about it.
The start of the week is a complete no-go. Tuesday arvo we got some chest-high swell at 5ft, but it's cross and chopped up with weak energy (1753). Not worth the drive. Wednesday and Thursday are big, pushing 10ft plus, but the wind is howling cross-onshore, making it a complete lumpy mess. All that energy (7200 and even 13569) is just going to waste. Forget it.
Things finally clean up Friday morning. The swell drops to a solid 7ft at 14 seconds, and it's glassy. Water temp is around 56°, which is about normal for the time of year. That's a decent window, but Friday arvo gets a bit of a ripple on it. Saturday is the one to circle, boys. Saturday morning is clean with light cross-off wind and 7ft of SW swell at 16 seconds. Then Saturday arvo the wind just dies completely – glassy conditions and 7ft of clean energy (1992). This is where Peak Rock (Big Island) will be at its best, not too big, nice lines, and you won't be fighting the wind. It's the standout of the next few days. Crowds are possible, so get in early.
Sunday holds onto that SW swell, but it's dropping to 5ft. The wind is fresh offshore, which will keep it clean, but the energy is fading (1159). It's still surfable, but the magic's gone. Monday is small and weak, back down to 3ft. Not worth the effort.
Then there's a bit of a lull before the next pulse. Tuesday and Wednesday next week pick back up to a solid 8ft, but the conditions are average at best – cross-onshore, choppy. Not great. Thursday the 17th looks sweet though. Morning is clean, light cross-off with 6ft, and the arvo goes glassy with 7ft of clean swell (2039). Another good window there.
Then we get to the big one. Saturday the 19th. This is where it gets serious. The swell jumps to a proper 13ft at 14 seconds, with a strong offshore wind. The energy is huge (10903). This is expert territory, no two ways about it. This is the best on offer for the whole forecast period, but it's not for the faint-hearted. Peak Rock is a reef, and with that much west in the swell, it could be firing, or it could be a washing machine. With that size, you're looking at a heavy day. If you're not sure, watch from the rocks first. The next couple of days after that are a mix of clean but fading surf, and then another pulse of 10ft+ that's got strong winds all over it, making it mostly a mess.
The second week is a bit more hit and miss. There's a promising window on Wednesday the 23rd, with 10ft of SW swell and light offshore winds, turning glassy in the arvo. That's another one for the experienced crew, but it's a bit further out, so don't book your flights yet. For the rest, it's a case of picking your moments and dodging the wind. The main takeaway: get on it Saturday the 12th and Thursday the 17th for some proper clean waves. That Saturday the 19th is the big boy, but respect it. This is Peak Rock, and when it's big, it's serious.

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.
