Marengo Surf Forecast and Surf Report

G’day, Rusty here. We’ve got a solid run of swell ahead for Marengo, but this ain’t for the faint-hearted—there’s some serious size on the way, and plenty of good wind to go with it. We’re looking at a few standout days, especially for the experienced crew. Let’s break it down.

Right now, Tuesday morning is a bit of a tease. There’s a 5ft SW groundswell rolling in with a long 16-second period, but the NNW wind is a cross-off, so it’s clean enough. The combined energy is moderate (1043). It’s more of a warm-up than a real go. Tuesday afternoon drops a touch to 4ft, still clean, but nothing special.

Wednesday, though, that’s when it starts to cook. Morning has a 6ft SW groundswell (16 seconds) with clean offshore wind from the W—beautiful conditions. The energy jumps to 1768. By the afternoon, it’s 7ft SW with the same perfect offshore, and energy hits 1804. This is a really solid day for the experienced surfer, with clean, lined-up waves at the reef and point.

Thursday the 3rd of September is a beast. Overnight the swell jumps to a massive 18ft from the WSW with a 14-second period, and the offshore wind is fresh at 35 km/h (22 mph). The combined energy is a whopping 13087. That’s a lot of power. Thursday afternoon sees it peak at 20ft, energy 16486. This is expert territory only—too big for anyone else. The wind is strong and offshore, so the faces will be clean, but paddling in will be a mission.

Friday the 4th backs off a bit to 8ft SW, with a long 15-second period, but the wind switches to a cross-off from the NNW. Energy remains strong at 3357. It’s still clean, but the direction isn’t as ideal. Saturday the 5th fires up again: 23ft WSW in the morning with a strong breeze from the WNW (40 km/h / 25 mph) and energy at 17722. This is huge, and while it’s clean, it’s going to be hard to paddle into. Afternoon drops to 16ft, still massive.

Sunday the 6th settles to 8ft SW with a 16-second period and a lighter cross-off from the NNW. Energy is 3182. The morning is clean and much more manageable for experienced surfers. This is a solid option if Thursday and Saturday are too heavy.

The standout days are Thursday the 3rd and Saturday the 5th for the big-wave crew – these are the biggest swells with clean offshore wind. If you’re looking for a more manageable but still pumping session, Wednesday the 2nd is a beauty, with clean 7ft waves and perfect offshore wind.

Late in the forecast, around Thursday the 10th of September, we get another spike: afternoon shows a 16ft WSW swell with moderate offshore wind and exceptional conditions—energy is 14788. This is a long-range call, so keep an eye on it, but it looks like another epic day for experts.

The first week is heavy, so beginners should sit this one out. The second week has smaller windows, but the quality remains high on the bigger pulses. There’s a couple of days around the 13th and 15th with smaller swell, but the wind is mostly clean or offshore. Overall, Marengo is delivering.
