Alright, Rusty here again. Let's break down the next 16 days at Marengo in the old units. This spot is a reef and point, beginner-friendly, fairly consistent, and gets a good look at SW swell. The go-to offshore wind is from the W. Conditions are a mixed bag, but there's one day that's a real standout.

We start Sunday July 12 with a bit of rain and a cross-off WNW breeze at 22 mph. The swell is 6.2 ft from the SW, period 12 seconds, and the combined energy is moderate at 1137. Marginal but clean. Sunday afternoon picks up: 11.5 ft of SW swell with a strong offshore wind at 25 mph, period 13 seconds, energy 5681. Big, clean, but tough to paddle into – experts only.

Monday July 13: 9.8 ft SW, 16-second period, cross-off winds in the morning, offshore in the afternoon. Energy is strong (4678 and 5577). Still

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.
