Alright, Rusty here. Let’s break down what we’ve got coming up for Marengo.

We’ve got a bit of a slow start, but things start cooking from Tuesday morning, July 7th, and there’s some real quality on the cards, especially for those who like a clean, lined-up wave. The reef and point setup at Marengo is your only real option here, so that’s where we’ll focus.

The water temp is sitting right around 58.5°F with a 1.6°F anomaly – that’s about average for this time of year, nothing unusual.

Right now, the forecast for this Sunday morning (July 5th) is a messy 11.5ft (6514) swell from the SSW, but with a 12 mph cross-onshore, it’s choppy and no good. Sunday afternoon drops to a zero-score situation. So, we sit it out.

Monday (July 6th) stays pretty ordinary. Swell drops to 5.6ft (1416) early, still from the SSW, but wind is light cross-shore. It’s surfable but nothing to call home about.

Here is the standout window. Tuesday morning, July 7th, is where it’s at. We’ve got a 3.6ft (832) groundswell from the SW with a long 17-second period, and the wind goes glassy – dead calm. That’s a recipe for clean, glassy conditions on a reef/point break. It’s a beginner-friendly 3.6ft, so this is the best option for everyone. It’ll have those long, drawn-out lines.

Wednesday morning, July 8th, picks up a bit more energy – 5.2ft (2150) from the SW with an 18-second period – but wind turns onshore, so it’s a bit of a shame. Still surfable, just not as clean.

Thursday, July 9th, gives us another solid morning: 4.3ft (820) from the SW, 15-second period, and again glassy conditions. Expect very clean surf. A true gem in the middle of the week.

After that, things drop off. Friday (July 10th) is small (3.9-4.6ft, 693-964) with cross-shore breezes. By Saturday, July 11th, it’s tiny and choppy – a skip day. Sunday, July 12th, is even smaller with strong cross-off winds – maybe one for the kites.

Then we get a pulse Monday morning, July 13th: 6.6ft (2058) from the SW, 16 seconds, but with a 16 mph cross-off wind. Clean, but that’s getting into expert territory for size and paddle-out difficulty.

From Tuesday, July 14th, through to Thursday, July 17th, we see more SW swell in the 4.3-6.6ft range (1346-1766) with fresh cross-off winds. It’s clean, but the wind is strong. Thursday the 16th is the pick of that bunch – 5.6-5.9ft (1455-1480) from the SSW with a moderate offshore. Excellent conditions for experienced surfers, but not for beginners.

The second week gets smaller and weaker. From Friday, July 17th, right through to Monday, July 20th, swell drops below 3.6ft (235-435) with light to moderate cross-off winds. Some clean days but very small. Great for a log, but not pumping.

Best on offer: Tuesday morning, July 7th – glassy, 3.6ft SW groundswell, perfect conditions.
For the experienced crew: Thursday, July 16th morning and afternoon – 5.6-5.9ft offshore SSW swell.

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.
