Righto, gather 'round. Rusty here. Let's have a look at what's coming our way for Marengo over the next couple of weeks.

We're kicking off a bit slow, but there's some proper juice on the horizon. The water temp's hangin' around average for the time of year, nothing too wild. The real story unfolds as we get into next week.

The first few days are a bit of a mixed bag. Wednesday the 8th has some decent sized swell, with 5ft to 7ft of long-period SW groundswell pumping in, but the wind is straight onshore. It's a bit of a mess, honestly, with a heap of energy in the water (2150 to 2327), but not much to write home about for a paddle. Might be more fun for the kite crew out there. Thursday the 9th looks much cleaner. The swell drops to a more manageable 4ft, still from the SW with that long 15-second period, and the morning is dead glassy with a NE breeze of 3 mph. That's your window for a clean, fun session on the points, even if it's not pumping. The energy is moderate (756).

Friday the 10th offers clean-ish surf in the afternoon with a light cross-offshore breeze, but the swell is dropping. Saturday the 11th is a write-off with a howling 22 mph cross-offshore wind and small swell. Then Sunday the 12th... hold onto your hats. The morning shows a massive 16ft WSW swell, with a very strong energy reading of 9911, but it's crossed up by a 22 mph NW wind. That's expert-only territory, and even then, it's gonna be a beast. The afternoon is a bit more manageable at 6ft with fresh offshore wind, but the morning is the real headline, for the brave few.

Now, for the absolute standout. If you've got the skills, Tuesday the 14th afternoon at Marengo is the one. It's not for the faint-hearted. We've got a 15ft WSW groundswell with a 15-second period and a moderate offshore breeze from the WNW. The combined energy is a beastly 11960, and the call is for exceptional conditions for expert surfers. The reef and point will be handling that long-period energy beautifully, creating some seriously heavy, thick lines. This is a big, powerful swell for big, powerful surfers.

Look out for that glassy morning on Thursday the 16th, with 5ft to 5ft of SW groundswell and no wind at all. A very clean, easy day compared to earlier in the week. Friday the 17th is also looking glassy and clean, with the swell sticking around 6ft to 7ft. Lovely conditions.

The second week fades out. From the 19th onwards, the swell drops right off and the wind turns ugly. By the 21st it's down to tiny 1ft dribble. The 22nd and 23rd show a small pulse of SW swell returning with clean winds, but nothing to get too excited about.

So, to sum it up: the best bet for a proper session is that Tuesday 14th afternoon for the experts. For everyone else, the glassy mornings of the 9th, and then the 16th and 17th are your best shots at clean, fun waves.

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.
