Righto, let’s have a look at what’s coming our way at Marengo.

The pattern is a real mixed bag – starts with a bang, then fades, then builds again. We’ve got a solid pulse of south-west groundswell rolling in this Friday afternoon, and that’s the standout session. Ok, let’s get into it.

Friday July 3rd afternoon – This is the pick of the whole forecast. A solid 15 ft SW groundswell, long period of 15 seconds, and a fresh offshore wind from the WSW. That’s going to be pumping at Marengo (reef and point). The combined wave energy is very strong (12876). With that size and period, it’s best suited for experienced surfers only – this will be too big for beginners. The water temp is 59°, about normal for the time of year. It’s going to be powerful, clean, and with a bit of luck, the crowd factor is manageable – we’ve got “sometimes” for crowds, so there’s hope you’ll find a peak. This is the one to point the car at.

Saturday July 4th – The swell drops to 10 ft in the morning, with a cross-off wind, clean but a bit lumpy. Still a solid 12 ft in the afternoon, period hanging at 13 seconds. Definitely surfable for those with a bit of experience, but not as epic as Friday. Conditions are clean, but the energy is a step down.

Sunday July 5th – Forget it. Cross-onshore ESE wind in the morning, 12 ft but choppy, and then onshore in the afternoon. This is a washout.

Monday July 6th – The swell backs right off. Morning is 6 ft with a light cross breeze, but by the afternoon it’s a glassy 5 ft. That’s tiny, but for a longboard or a funboard, that afternoon session with glassy conditions and clean lines could be a real treat. Wave energy is weak (886). Good for a paddle and a few cruisy ones.

Tuesday July 7th – The morning is glassy with a 3 ft swell, long period of 16 seconds – clean but tiny. Afternoon picks up to 4 ft with a light cross-off. Both sessions are clean, but it’s small.

Now there’s a gap of a few days where the quality’s not there.

Wednesday July 8th – A bump up to 7-7 ft, but with cross-onshore winds. Choppy and not great.

Thursday July 9th – Onshore wind, poor conditions. Hard pass.

Friday July 10th – Small, 4 ft, light cross breeze. Marginal.

Saturday July 11th – Dropping even further, 2 ft. Hardly worth a wet-suit.

Sunday July 12th – A bit of a come-back. Morning is still tiny (3 ft), but in the afternoon we get 5 ft at 17 seconds from the SW, with a clean cross-off wind. The energy is moderate (1727). This is the start of a new pulse.

Monday July 13th afternoon – This is another stand-out. 10 ft SSW groundswell, period 12 seconds, and a fresh offshore wind from the W. The combined energy is strong (4256). It’s a bit shorter period than the first pulse, but still solid and clean. This is good for experienced surfers – big and powerful.

Tuesday July 14th – Strong winds (25 mph) spoil the party. Clean but very windy, and the swell drops to 5-6 ft. Hard work.

Wednesday July 15th – Showers and moderate wind, swell around 7 ft. Choppy. Not great.

Thursday July 16th – Small, messy, poor conditions.

Friday July 17th – The swell picks up again to 6 ft, and by afternoon we have a clean 5 ft with a light cross-off. That afternoon session is a good one – clean conditions, decent energy (1185), and a long period of 15 seconds giving shape.

Saturday July 18th – Finishes with a small, clean note. 5 ft in the morning, 4 ft in the afternoon, both clean. The afternoon glass-off could be a lovely end to the run.

Best on offer: Friday July 3rd afternoon for the big swell and offshore conditions – that’s a proper session for the experienced crew. Second best is Monday July 13th afternoon – another solid pulse with offshore wind. The rest is small, or windy, or just average.

Remember, long-range stuff like that second week is promising but less certain.

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.
