Alright, this is Rusty, and I’m looking at what’s on the cards for us here at Marengo over the next couple of weeks. There’s a bit of a slow start, and a whole lot of waiting, but there are a few moments that will fire.
First things first – we’ve got a slow kick-off. The first solid recommendation isn’t until Friday the 3rd of July. Up until then, it’s mostly flat or too messy to even think about. So we’re burning a few days right off the bat.
Now, Friday morning the 3rd, Marengo (reef and point) sees the party start. We’re talking a meaty 15 ft swell from the WSW, with a period of 16 seconds. That is proper groundswell energy, and the combined energy is very strong at 14727. The wind is a strong offshore at 25 mph, which will clean things right up. But listen – at 15 ft, this is for experienced surfers only. That energy is huge, and the offshore will hold it up, but the paddle-out is going to be a beast. Beginners, stay on the beach for this one. The water is sitting at 59°, which is pretty standard for this time of year.
Friday afternoon keeps the quality high. Still 15 ft, shifting a little more SW, with a 15-second period. Wind drops to a fresh 22 mph offshore. It stays clean and powerful. This is still big and demanding, but if you’ve got the skills, Friday is the standout of the entire outlook.
Saturday the 4th has dropped a touch: 13 ft in the morning, 12 ft in the afternoon, period dropping to 13 and then 12 seconds. Wind goes cross-offshore. It’s clean but the energy has mellowed some. Still a solid day, but not as intense as Friday.
Sunday the 5th takes a dive. The wind swings cross-onshore and onshore, with a 12 mph breeze from the ESE/E. The swell is still 12 ft to 10 ft, and the period is long (17 seconds), but the wind messes it up. Choppy, blown-out. Not worth paddling out.
Monday the 6th and Tuesday the 7th, the swell drops significantly. We’re looking at 6 ft down to 3 ft. The wind is light and variable, offering clean conditions on Tuesday. But the energy is low (592-1301), meaning very weak, small surf. Good for a longboard or a learner session, but not a standout.
From Wednesday the 8th through Thursday the 9th, the swell picks back up to around 7 ft, but the wind is onshore and cross-onshore. It’s choppy and messy. A couple of those days have light winds, but the direction is wrong. Not your best bet.
Then, Friday the 10th of July – worth talking about. Morning has clean 4 ft swell with a NNW cross-offshore wind. But the afternoon is glassy. Flat calm, 4 ft, 16-second period from the SW, energy around 692. This is small but perfect. Clean, glassy, gentle. The kind of afternoon you take off work for. A real hidden gem in the middle of this run.
Saturday the 11th and Sunday the 12th continue with small 4-4 ft swell, cross-off to cross winds. Clean-ish but weak. Really only for the log or a fun cruiser.
Monday the 13th, the swell bumps up to 5-5 ft, but wind is cross to cross-onshore, so it’s choppy again. Not great.
Tuesday the 14th – another spike. Morning has 10 ft from the SSW, with a cross-off wind. Afternoon jumps to 13 ft, cleaner with a gentle cross-off. That afternoon session could be a beauty if you’re ready for big waves. The energy at 6880 is strong.
Wednesday the 15th and Thursday the 16th get blown out by a strong SE wind, cross-onshore, with swell still 8 ft to 12 ft. Messy, choppy, not good for surfing. I’d say this looks more interesting for kite surfing than paddle surfing.
Through Friday the 17th, we drop back to 5-6 ft, but the wind stays cross-onshore. Choppy and poor.
Finally, on Saturday the 18th, we end the run nicely. Morning and afternoon are both glassy, with a tiny 3 ft of clean, long-period groundswell from the SW. The energy is very low (425-598), but for a tiny, clean, glassy day on a longboard, it’s a beautiful way to sign off.
So, the true standouts – without a doubt – are Friday the 3rd of July (both sessions), and the afternoon of Friday the 10th of July. Friday the 3rd is for the big-wave crew; Friday the 10th is for everyone who loves perfect, small conditions.
Stay stoked,
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.
