Marengo Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what’s cooking at Marengo over the next couple of weeks.

Straight up, this is a classic case of big energy but you’ve got to pick your moments. The first few days are pumping with a serious swell, but it comes with a lot of wind, so we’re not looking at perfect conditions straight away. We’ve got a solid run of swell coming through, but the real gems are tucked away in the middle of the week and then again further out.

We kick off on Wednesday, 29 July, and it’s all about size. We’re looking at a 16 ft SW swell with a 16-second period, carrying a massive combined energy of 18611. That’s a lot of power. But the wind is a cross-off SW breeze at 22 mph, so it’s going to be a bit of a battle. The surf is clean, but the conditions are marginal. It’s a big, powerful ocean out there, and for the experienced crew only – this is way over the 8 ft mark. It’s a reef and point set-up, so that long period should wrap in nicely, but the wind is the main factor here.

By Thursday, 30 July, things settle down a notch. The swell drops to 3 ft from the SW on Thursday morning, with a 14-second period, and the combined energy is down to 964. But the wind has swung to a W 9 mph offshore breeze. That’s the ticket. The report says "expect very good surf conditions" and it’s clean with a gentle offshore. This is a solid window for a longer board, but it’s small. The afternoon kicks up a bit to 8 ft from the SW, with a solid 13-second period, and the wind stays offshore from the WSW. That’s "excellent surf conditions for experienced surfers" – a standout for the week. The combined energy jumps to 3019, so there’s proper push. If you’re an experienced surfer, Thursday afternoon is your session.

Friday, 31 July, is smaller again, with 4 ft and 4 ft from the SSW and SW, and light cross-off winds. It’s clean, but not a standout.

Saturday, 1 August, has a mixed bag. The morning is tiny at 3 ft, but the afternoon brings a 6 ft SW swell with a 17-second period, a long period groundswell, and the wind is a clean cross-off from the NNW. The combined energy is 3092, and it’s described as "excellent surf conditions for experienced surfers". That’s another top pick, but it’s a bit of a step up in size.

Sunday, 2 August, holds the same 6 ft SW swell, but the wind picks up to a fresh 19 mph cross-off from the NNW. It’s still clean, but the wind is stronger, so it’s not as clean as the day before.

We’ve got a bit of a lull in the quality from Monday, 3 August, through to Wednesday, 5 August. The swell drops, the wind is onshore or cross-off, and the conditions are generally marginal. There’s a window on Monday morning with a fresh offshore from the W at 22 mph, but the swell is only 4 ft. It’s clean, but the energy is dropping.

The next true standout is on Friday, 7 August. The afternoon session is looking juicy. A 4 ft SW swell with a 19-second period – that’s a very long period groundswell. Combined energy is 1502, and the wind is a light cross-off from the NW. It’s described as "excellent surf conditions for experienced surfers". This is a late-week highlight, but it’s over a week away, so keep an eye on it.

After that, from Saturday, 8 August, the wind turns messy onshore and cross-on, and the quality drops off. There are a few clean windows further out, like on Tuesday, 11 August, with a 4 ft SW swell and a moderate offshore, but the swell is small.

The last big bump we see is on Wednesday, 12 August, with an 12 ft SW swell packing a combined energy of 7469, but the wind is a fresh cross-shore at 22 mph, creating a lumpy cross-chop. That’s only for the brave and the experts.

So, overall, the best on offer is Thursday afternoon, 30 July, and then Saturday afternoon, 1 August. Friday, 7 August, is a promising long-range option, but it’s a week and a half out. The water temperature is about what you’d expect for this time of year at Marengo, nothing unusual.

Stay stoked.

Rusty.
