The Lowdown
Alright, surfers, Rusty here, looking at the forecast for the next couple of weeks.
To kick things off, the water is running at 56°F, which is about average for this time of year. Not too crazy, just your standard fair.
We've got a bit of a quiet start, but things are brewing. The most consistent action is at Peak Rock. It's a reef break, and it's fairly consistent, so there will be waves to be had.
Tuesday the 18th morning looks like a sneaky good one to open the account. We've got a 4ft SW groundswell with a 14-second period, and the northeast wind is light. The energy is moderate, but the conditions should be clean. It's not the biggest, but it could be a fun one on the reef.
The middle of the week is a write-off. Wednesday the 19th and Thursday the 20th have some lumpy, onshore energy or just too much wind. You'll be fighting the elements more than riding waves. We'll see a small window Thursday afternoon with a little 3ft WSW bump and light winds, but it's nothing to get too excited about.
Now, let's talk about the real standout. Friday the 22nd of August into Sunday the 24th is where it's at. Friday afternoon sees the swell start to push up to a solid 8ft from the southwest, and the energy jumps way up. The wind is light and cross-offshore, which for a reef like this is going to be excellent. This is for experienced surfers only – 8ft is proper size, so the beginners should give it a miss. Saturday the 23rd keeps that strong energy (7ft on the morning) with a SW swell, but the real gem is Sunday afternoon. The wind drops to glass, the swell stays at a solid 7ft, and the long-period SW groundswell will be lining up on the reef. That's going to be a session to remember.
After that, it gets a bit more interesting. Monday the 25th has a bump in size again, with 5ft surf and a fresh offshore flow, and then Tuesday the 26th sees the swell push back up to 7ft with moderate energy. The winds are decent, but it might be a little more mixed. The second week, we're watching Wednesday the 28th of August. The wind drops off, and we see a clean 8ft WSW swell with strong energy. That's another one for the experienced crew.
The end of the run gets messy. Strong winds from the east and rain showers will chop things up from the 29th into the 30th. Early on the 31st, we see a strong offshore, but it's blowing a gale, making it nearly impossible to paddle into. It settles down a touch, but the run into the first week of September looks pretty underwhelming, with small, weak swells.
So, to sum it up: the absolute pick of the bunch is the Saturday the 23rd afternoon glassy session, followed closely by Friday the 22nd afternoon and Wednesday the 28th. Mark those in your calendar.

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.
