Marengo Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s talk about what’s shaping up at Marengo over the next couple of weeks.

Right off the bat, we’re looking at a solid run of swell, but it’s not all clean. Tuesday morning (28 July) is a bit of a write-off with a fresh cross-off breeze making things messy despite some waist to chest-high swell. The real kick-off comes Tuesday afternoon. The wind swings offshore and we get a solid 6ft SW groundswell with a very long 15-second period. The energy is pumping (1547), and it’s clean. That’s the first proper session window.

Wednesday (29 July) is the standout of the first week. We’ve got a massive 16ft to 18ft SW groundswell rolling in with a long 15-16 second period. The combined energy is huge (18238 and 16559). This is serious, powerful stuff. The wind is a cross-off, so it’ll be clean, but this is only for experienced surfers. Beginners, stay on the beach. This is big, heavy, and will have plenty of grunt. It’s the best on offer in the whole outlook.

Thursday (30 July) drops back to a much more manageable 8ft SW groundswell with a 13-second period, and the wind is offshore. It’s clean, good for experienced surfers, but not the monster the day before. Friday (31 July) is smaller again, with light breezes and clean conditions, but nothing to get too excited about.

Saturday (1 August) has a tricky morning with a cross-shore wind, but the afternoon is interesting. A 6ft SW groundswell with a very long 18-second period rolls in, and the wind is light and cross-off. The energy is building (3084). That long period will make the waves peel nicely here at this reef and point.

Sunday (2 August) and Monday (3 August) are messy with onshore and cross-shore breezes. The surf is around, but it’s not worth the paddle for the quality on offer.

Now, we hit a bit of a lull, but the second week has a couple of good days. Wednesday (5 August) is a hidden gem. The morning has a 5ft SW groundswell with a very long 18-second period, and the wind is a light cross-off. The afternoon goes glassy. That’s a window for some smooth, lined-up waves. The energy is solid (2889 and 1371). This is a top pick for the second week.

The run from Thursday (6 August) to Sunday (9 August) is mostly small or onshore, with a brief glassy spell Sunday afternoon. Then Monday (10 August) brings a bigger 8ft SW groundswell, but the wind is messy, so it’s not the cleanest.

The real wildcard is Tuesday (11 August) afternoon. The wind goes offshore, and we get a solid 13ft WSW groundswell. The energy is massive (7273). This is big, powerful, and will be a heavy wave for the crew who want it. And then Wednesday (12 August) is a 23ft WSW groundswell – the biggest of the whole forecast. The wind is a moderate cross-off, but the data says it’s simply too big for this break. That’s a day to watch from the cliff.

So, the best bets: Wednesday (29 July) for the big, clean, expert-level swell. And for the second week, Wednesday (5 August) for the glassy, long-period, clean conditions. The crowds are “sometimes” here, so you might have some company, but with that quality, it’s worth it.

Rusty.
