The Lowdown
G’day, Rusty here. Let’s run through what’s cookin’ over the next couple weeks.
We’re startin’ Thursday the 13th of August with a big pulse of long-period groundswell from the SW. The ocean’s got serious energy—combined energy’s at 5036—and the water’s a touch warmer than usual at 56°, just above average for the time of year. Thursday morning’s got a 10-foot swell with a cross-off breeze, so it’s clean but only for the experienced crew. That afternoon, the wind lightens up from the west and conditions turn excellent for the guys who can handle it. Friday the 14th still has that 10-foot SW swell in the morning with clean faces, but the wind picks up. Friday afternoon gets lumpy with a cross-shore breeze. Saturday the 15th looks messy with cross-on winds and a drop to 8 feet, not worth the effort.
Sunday the 16th cleans up with a 6-foot swell and a light NE cross-off breeze in the morning—nice and tidy for intermediates. Monday the 17th stays around 5 to 5 feet but gets choppy. Tuesday the 18th sees a clean 4-foot swell with light cross-off winds, but it’s small. Wednesday the 19th the swell drops to 3 feet with offshore wind but barely any push. Thursday the 20th improves with a clean 5-foot WSW swell and glassy winds in the afternoon. Friday the 21st and Saturday the 22nd have fresh winds and small swell, though Saturday afternoon gets a clean offshore.
Now for the standout: Monday the 24th of August, we get a solid 8-foot SW swell with a 15-second period and a strong offshore NW wind at 22 mph, combined energy at 3154—real power, but experts only. Monday afternoon the wind hits 28 mph offshore, clean but hard to paddle into. Tuesday the 25th gets messy with cross-shore winds. Wednesday the 26th has a 10-foot WSW swell with cross-off breeze but strong wind. Thursday the 27th of August is a beast: combined energy hits 12607 with a 13-foot SW swell and 16-second period, but onshore winds from the SSE ruin it for paddle surfing—that’s more a kite day. Friday the 28th is the real gem: morning brings glassy 6-foot SW swell with a light NE breeze, excellent conditions for the experienced.
Best bets are Thursday afternoon the 13th and Friday morning the 28th. There’s a long stretch of marginal days from the 15th through the 23rd, but keep an eye out.
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.
