Marengo Surf Forecast and Surf Report

Alright, this is Rusty, checking in with your local surf outlook for Marengo.

We’ve got a bit of a slow start, but don’t write the week off. The real juice is building up later, with a couple of absolute standouts that have me proper excited. The water temp is sitting around 57°, which is pretty much what you’d expect for this time of year.

First up, Tuesday the 25th morning. It’s not the biggest, but it’s clean. We're looking at a 5ft SW swell (moderate wave energy, 1041) with a 13-second period and light NW cross-off winds. That’s a solid, workable wave for the beginner-friendly Marengo reef and point setup. The afternoon drops off a bit in size and the wind picks up, so get on it early.

Wednesday the 26th is a write-off for quality; the wind is up, making things messy. Thursday the 27th offers a tiny relief with a clean 3ft SSW swell in the morning, but it’s small.

Alright, here’s where it gets good. Friday the 28th is your first standout morning. The swell jumps to 5ft from the SW, with a very long 18-second period and light wind. The combined energy is strong (1652). This is proper groundswell, offering unreal shape and power on the point. It’s not for beginners at over 5ft, but experienced surfers will be in heaven. That long period means the sets will be clean and well-spaced.

Saturday the 29th keeps the quality high. The morning has a clean 4ft SW swell with offshore wind, and by the afternoon it’s pushing 6ft with moderate offshore breezes (energy jumping to 2034). This is excellent.

Sunday the 30th is the biggest call of the first week. Morning sees 8ft SSW groundswell (strong energy at 3639) with a 17-second period and light cross-off winds. The afternoon pumps up to 10ft (very strong energy, 5110). This is big, powerful stuff – expert-only territory. You’ll need your wits about you. Monday the 31st is a gem, with a 7ft SW swell and glassy conditions. That’s a rare combo.

The first few days of September thin out a bit, with onshore winds and messy conditions from the 1st to the 4th. There’s some swell, but the quality just isn’t there.

Now, for the true, late-period standout: Saturday the 5th of September. The morning is ridiculous. A massive 13ft WSW swell (exceptional energy, 8681) with glassy, off-conditions. This is as good as it gets for the experts. The afternoon bumps up to 16ft SW, but the wind swings cross-onshore, which will chop it up. The morning session is the one to circle on your calendar. It’s a week and a half out, so it’s a promising long-range call.

After that, Monday the 7th cleans up again with a 7ft SSW swell, and Tuesday the 8th afternoon offers a surprise with a 3ft SW swell but a period of 20 seconds – super long period, fantastic for the point, producing great shape even at that size.

So, to sum it up: don't bother this weekend, but lock in Friday the 28th morning for the first real score, and keep your fingers crossed for Saturday the 5th of September morning – that could be the session of the year.

Rusty.
