Righto, grab yourself a cuppa and let’s see what Marengo’s got cookin’ over the next couple of weeks. We’re in for a proper mixed bag – some real sweet moments, but also some wild, gnarly days that’ll sort the men from the boys.
First up, Monday the 6th of July has got my heart pumping. We kick off with a solid SSW groundswell – 6 ft at 14 seconds – and glassy conditions with just a whisper of northerly air. The wave energy is strong (1439), and with the water sitting at 59°F, about 2°F warmer than usual for this time of year, it’s a nice bonus. This is proper, clean, lined-up surf for experienced surfers, not the place for a learner today. Monday afternoon stays glassy with a 5 ft swell, still clean as a whistle.
Tuesday the 7th eases off a touch but is still lovely. Morning brings 4 ft of clean, glassy surf from the SW with a very long 17-second period. That long period means the sets will be fat and forgiving, and paddling out should be a breeze. By afternoon, wind shifts easterly and it gets a bit trickier – still ridable but not the standout.
Wednesday the 8th is a funny one. The swell builds to 5-7 ft with a solid 17-18 second period, and the wave energy is through the roof (2150-2327), but the onshore easterly breeze makes it lumpy and hard to read. If you’re a local who knows the bank, you might get some, but for most of us, it’s a skip.
Now, Thursday the 9th morning is a wildcard that has me keen. Glassy again, with a 4 ft SW groundswell at 15 seconds, and the wave energy is moderate (740). It’ll be clean and should offer up some fun ones. Friday the 10th holds similar size with light cross-offshores and clean conditions – a solid session for an intermediate.
Alright, brace yourselves. Saturday the 11th and Sunday the 12th are a write-off. Strong winds and rain, with swell dropping to under 3 ft and weak energy (192-298). The Sunday has strong offshore winds, but the waves are tiny and hard to paddle into – leave the kite at home too, it’s not worth it.
But hold onto your board shorts, because Monday the 13th of July is where it gets *proper*. A massive 18-20 ft SW swell rolls in with an insane 18319 wave energy rating. This is big, serious surf – experts only, no doubt. The wind is offshore, so the faces will be clean, but this is a day for charging. Tuesday the 14th settles to a much friendlier 4-5 ft with a classy 17-19 second period and gentle offshore breezes. This is your easy morning highlight of that week – clean, lined up, and not trying to kill you.
Wednesday the 15th gets big again – 12-13 ft with strong offshore winds. It’s clean but massive, again just for the experts. Then, the true standout of the whole outlook: Thursday the 16th of July. Morning brings a 16 ft SW swell with only a slight offshore breeze, glassy and clean. The wave energy is 17401. This is exceptional, big-wave territory for the brave. Afternoon drops to a 10 ft SSW swell with light offshore winds – still big but a bit more manageable.
After that, the last few days from Friday the 17th to Tuesday the 21st are a messy mix of building and dropping swells, with strong winds returning. Saturday the 18th has some 7 ft swell with clean but strong cross-offshore winds, but it’s not the quality of what came before. By Sunday and Monday, the wind is fresh and cross, with lumpy conditions and dropping scores. Not the time to get excited.
So, the pick of the bunch? Monday morning the 6th of July for that first clean, lined-up session, and Thursday morning the 16th of July for the big-wave punters looking for that exceptional, glassy, heavy day at Marengo. The smaller, clean sessions on the 9th and 14th are your solid, fun fallbacks.
Stay safe out there and keep an eye on the sky.

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.
