Marengo Surf Forecast and Surf Report

Alright, let’s get into it.

First up, the long-range looks promising, but we’ve got a pretty flat and messy start to get through. The next week or so is all about waiting for a solid pulse of southwest groundswell to line up with some offshore winds. It’s gonna be a waiting game for the good stuff.

The first real window opens up on Monday the 10th. We’ve got a new southwest swell starting to fill in, showing 6ft with a 19-second period. That’s a proper groundswell, and it’s got some serious energy behind it, with combined energy around 1999. The wind is cross-offshore in the morning, which will keep things reasonably clean, but the tide might be a bit funky, so it’s not perfect. Still, it’s the first decent surf of the period.

The swell dips a little on Tuesday the 11th, down to 4ft, but the period stays long. The wind is still cross-off, so there are some clean waves to be had, but it’s not a standout.

Wednesday the 12th is where it starts to get more serious. The morning sees the swell building back up to 7ft from the southwest with a 16-second period and a strong offshore wind. That’s a good combo, still, the guidance calls it marginal, likely due to the tide. The afternoon is a different story though. The swell jumps to 13ft from the west-southwest, with a 14-second period and a huge energy reading of 9307. Wind is fresh offshore. This is the big one. At this size, it’s only for experienced surfers. The period is a touch shorter, but the power is undeniable. This is the standout of the whole window.

Thursday the 13th keeps the energy high. We’re looking at 8ft of southwest swell with a 15-second period, and the wind is offshore all day. The wave comment calls it "excellent surf conditions for experienced surfers." This is the time to be out there if you know what you’re doing. The energy reading is still strong, around 2779 in the morning and 2830 in the afternoon.

Friday the 14th sees the swell still pushing 10ft in the morning with a 16-second period, but the wind swings to cross-offshore, which takes the shine off a bit. It’s still good, but not as clean as the day before.

The weekend rolls in and the swell eases. Saturday the 15th has 6ft of swell, but the wind turns light and cross-onshore, which messes up the surface. It’s not great.

From Sunday the 16th through to the middle of the following week, it drops right off. We’re looking at poor surf with onshore winds and weak energy. It’s a proper flat spell, a solid few days of nothing.

There’s a glimmer on Thursday the 21st with a small, clean 2ft wave and glassy conditions in the morning, but that’s about it. Then it gets a little bigger again on the 23rd, but the wind is onshore and it’s messy. Not worth it.

The one true standout here is Wednesday the 12th afternoon. That’s the day. Big, powerful, and offshore. The other highlight is Thursday the 13th – still big, still clean, and for the experienced crew.

So, be patient. The surf comes, and when it does, it’s big. Don’t blink.
