Alright, Rusty here, giving you the rundown on Marengo in feet. This reef and point loves a solid SW groundswell, and the next couple of weeks have a real mix.
To start, the water temp is about average for this time of year, nothing strange. Thursday the 9th morning is a beauty. We’ve got a clean 4ft SW swell with a 15-second period, total energy of 742, and a dead flat, glassy 3 mph northerly wind. That’s prime real estate at the point, clean and lined up. Crowds can pop here, but for that quality, you deal with it. This one’s a standout.
Thursday afternoon gets onshore, so hit it early. Friday the 10th is still good with a slight cross-off breeze and the same 4ft swell.
Saturday the 11th is a mess. Wind hits 22 mph, dropping the swell to 3ft. That’s kite-surfing weather, not for a paddle board.
Then things get serious for the heavy crew. From Sunday the 12th to Tuesday the 14th, Marengo is a big-wave beast. Sunday morning the 12th has 8ft of SW swell with 25 mph offshore winds, energy at 2886. Sunday afternoon jumps to 13ft with 8152 energy. Monday the 13th afternoon peaks at 20ft of WSW swell and 14519 energy with 25 mph offshore wind. Tuesday the 14th afternoon is 18ft with 19547 energy and 28 mph offshore wind. It’s clean, it’s powerful, and with a 16-17 second period on a reef, it’s for experts only. This is a major standout for the big-wave chargers, but absolutely not for the average surfer.
The cross-shore wind messes things up from the 15th, and Friday the 17th is a total blown-out washout.
We get a nice mellow gap on Saturday the 18th afternoon. Glassy conditions, 5ft of SSW swell, energy at 1083, and zero wind. That’ll be a beautiful, clean little session.
The following week is steady but smaller with clean offshore breezes. Monday the 20th afternoon shows a long-period 3ft SW swell with a clean offshore wind.
The big long-range call is Thursday the 23rd. Thursday afternoon shows a clean 10ft SW swell with a 16-second period, energy at 4034, and a light 6 mph cross-off breeze. That’s huge, clean, and lined up. It’s two weeks out, so keep an eye on it, but that’s the one to get excited about.
Bottom line: For the big stuff, circle Thursday the 23rd afternoon. For the classic, smaller, clean waves, go for Thursday the 9th morning or Saturday the 18th afternoon.
Rusty.

Information about the Marengo Surf forecast
The above surf forecast table for Marengo provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Marengo can be found by selecting the local surf guide option on the grey menu. Our Marengo 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 (Marengo) 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 Marengo 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.
Marengo is 93 km (58 miles) from the city of Geelong West. If you plan a holiday in Cape Otway, look for hotels and other accommodation in Geelong West. Geelong West has rooms for a wide range of budgets as well as car hire and transport links.
