The Lowdown

Alright, Rusty here. Let's have a look at what's coming our way for Peak Rock.

First up, the water temp is sitting at 57°, which is pretty much right on the money for this time of year, nothing out of the ordinary there.

Right now, we're in for a rough start. Monday the 7th is a write-off. We've got a 7ft SW swell but it's being hammered by a strong 22 mph cross-onshore wind, making for lumpy, poor conditions. The combined swell energy is moderate at 1232, but it's just not surfable. The afternoon cleans up a little in height but the wind stays onshore and choppy.

Tuesday the 8th is where it gets interesting. The swell drops to 4ft in the morning with a really long 18-second period, and the wind swings to a light W cross-off, giving us clean conditions. The combined energy is strong at 1684. This is a proper groundswell. Afternoon sees a cleaner 5ft SW swell with a cross-shore light breeze. It’s not huge, but for a reef break like Peak Rock, that long period energy should produce some nice, shapey lines. It's a bit of a slow burner, but the standout session of this first week.

Wednesday the 9th, forget it. The swell jumps to a massive 12ft to 13ft with a super strong 20-second period, but the wind is back to a nasty 22 mph cross-onshore. Combined energy is off the charts at 11792, but it’s a lumpy, blown-out mess. This is for experts only, and even then, it's not going to be pretty.

Thursday the 10th still has a big 12ft SW swell in the morning with a moderate cross-shore wind. The energy is still massive (9983), and the conditions are listed as marginal. It could have some heavy, powerful waves, but it's not clean. The afternoon drops to 10ft but gets a cross-onshore wind again.

Friday the 11th sees the swell ease to 7ft with a 14-15 second period, but the wind is light cross to cross-onshore, leaving a bit of a chop on the face. Manageable, but nothing to write home about.

Now, keep your eyes on Saturday the 12th. This is the best bet of the whole outlook. The swell is still a solid 7ft from the SW with a 16-second period, but the wind goes glassy. Both morning and afternoon are showing glassy conditions with a slight air. Combined energy is solid at 2267 and 1774. For a reef break, glassy conditions on a 7ft groundswell is a recipe for some truly epic waves. This is a standout, but only for experienced surfers as it's over 5ft.

After that, we have a long run of smaller, cleaner days from Sunday the 13th through Monday the 14th. The swell drops to 4-5ft and the wind goes fresh offshore from the N/NW, giving clean walls. The energy is low to moderate, but for a small-wave board or a longboard, it’ll be fun and uncrowded.

We get another pulse of big swell around Tuesday the 15th with 10-12ft, but the cross-onshore wind returns. Wednesday the 16th is similar, with 8-10ft SW swell and a light cross to cross-onshore wind, making it lumpy.

The end of the second week sees a return to offshore winds on Thursday the 17th, with a 5ft SW swell. It’s small but clean. Friday the 18th gets a strong 28 mph offshore wind, which will make for clean surf but a serious battle to get out. You'll want to be fit. Combined energy is moderate at 1072 and 1189.

Saturday the 19th brings a fresh cross-shore wind and a 7ft SW swell. Not great. But the afternoon gets interesting again with a 8ft SW swell, a very long 19-second period, and a light cross-onshore breeze. The energy jumps to 4499, so that's another promising window for the end of the outlook.

The final days from the 20th to the 22nd offer a mix of clean but small conditions and a couple of bigger, longer-period swells with light winds, but the consistency isn't there. The standout is still that glassy Saturday the 12th.

So, if you can only paddle out once, make it Saturday the 12th. After that, keep an eye on Tuesday the 8th for the long-period groundswell and the 19th for a late-afternoon session if the wind plays ball.

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.
