G’day, I’m Rusty, and I’ve been reading the water at Marengo. This reef and point break is the only spot worth talking about for the next couple of weeks—got clean glass, some real power, and a few days that’ll test your nerve.
The first real surf shows up Monday, July 6th. Marengo’s picking up a solid SSW groundswell, 6ft with a 14-second span. The combined energy is 1443, and with glassy conditions and a light N breeze, it’s gonna look perfect. Water temp’s about average for the time of year. This is good quality, but at that size and period, it’s for experienced surfers—beginners will want to sit this one out.
Tuesday the 7th stays glassy in the morning, 4ft SSW swell, but the period jumps to 17 seconds. That’s long-period groundswell—shapes up nice on the point, but might break a bit straight on the beach. Energy’s still solid at 786. By the arvo, a cross-on wind messes it up a bit.
Wednesday the 8th brings a big pulse. Morning: 5ft SW swell, 18-second period, offshore E wind, energy at 2168. Clean, powerful, but tide-dependant. Afternoon jumps to 7ft at 17 seconds, energy at 2327—again, questionable. This is expert territory.
Thursday the 9th and Friday the 10th offer a breather. Thursday morning is glassy with 4ft SW swell at 15 seconds—a proper session without the chaos. Friday morning is cross-off, clean, 4ft at 15 seconds, energy 800. Solid.
Saturday the 11th is blown out by a strong N cross-wind at 30 km/h—small, weak 3ft swell, energy barely 350. Sunday the 12th starts with strong offshore wind and tiny 1ft—kite-surfing weather. The afternoon picks up to 6ft but with a short 9-second period and strong W wind; it’s messy.
Now the big one. Monday, July 13th afternoon: a monster 13ft SW swell, 12-second period, energy at 7698. Moderate offshore wind. This is exceptional for experts only—size, power, and clean faces. If you’ve got the stones, go.
Tuesday the 14th stays big: 10ft morning, 7ft afternoon with offshore wind. Both clean, but all about positioning on the reef. The week after settles into a nice groove—Wednesday the 15th, Thursday the 16th, and Friday the 17th have clean, glassy or cross-off mornings with 5ft to 6ft SW swell and good 14-16 second period. Energy stays moderate to strong. These are your best all-round days.
The final week gets wind-affected and smaller. By Monday the 20th and Tuesday the 21st, the wind’s up and the swell’s messy.
Bottom line: the first few days are clean and quality for experienced surfers, Monday the 13th is a bomb for experts, and the middle of the second week offers the best balance.
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.
