Marengo Surf Forecast and Surf Report

Alright, this is Rusty comin' at ya from the Marengo area. Let's have a look at what's on the table for the next couple of weeks.

First things first, the water temp is sittin' at 58°, which is about normal for this time of year. Nothin' wild there.

We've got a pretty solid run of surf ahead, but it takes a sec to get goin'. The first real action kicks off Friday morning, July 17th. We're lookin' at a solid 7 ft SW groundswell with a 16-second period, packin' a hefty 2033 combined energy. That's a lot of power. The wind is a light 5 km/h NNW cross-off, so it's gonna be clean, but this one is for the experienced crew only. Too big for the groms. The afternoon holds a similar 6 ft swell (1654 energy) with WSW wind, still clean.

Saturday, July 18th, settles down a notch. The morning is 4 ft SW swell (639 energy) with a 10 km/h WNW cross-off, still clean. But the real gem is Saturday afternoon – glassy conditions with a 4 ft SW swell (451 energy). That's smooth, clean, and perfect for a long session. Sunday, July 19th, keeps the glassy theme going with a tiny 3 ft SSW swell (330 energy) and light winds. It's small, but clean.

The week ahead stays consistent and clean, with waist-high surf from Monday through Wednesday, all with cross-off or offshore winds. Not a standout, but dependable.

Now, pay attention. Thursday, July 23rd, is where it starts to get serious. The morning shows a 6 ft SW swell (1480 energy) with a 15 km/h WSW offshore wind. That's gonna be clean, well-shaped, and pumping. The afternoon is a touch smaller but still excellent.

Then we get to the big one. Friday, July 24th. This is the standout of the entire forecast. We're talkin' a massive 16 ft SW swell (12,756 energy) with a 14-second period. The wind is a steady 20 km/h offshore from the west. This is exceptional, expert-only territory. If you know what you're doin', this is the day. The afternoon holds a 15 ft swell (9,884 energy) with a lighter 15 km/h offshore. It's gonna be a big, clean, powerful day.

The swell drops off for the weekend, but there's still a decent 6 ft SW swell on Saturday, July 25th, though the wind gets a bit cross-off. Sunday, July 26th, looks clean again with 4 ft SW swell and a solid offshore breeze.

There's a gap in the quality after that. Monday and Tuesday, July 27th and 28th, see a return of bigger swell (6 ft up to 13 ft) but the wind cranks up to 30 km/h cross-off, makin' it messy and choppy. Not ideal. Wednesday, July 29th, has a strong 40 km/h offshore wind. It'll be clean, but that wind is a beast – hard to paddle into, and only for the strongest.

The end of the run sees a return to cleaner conditions. Friday, July 31st, has a nice 4 ft SW swell (1,340 energy) with a 20 km/h offshore wind in the afternoon. It's a solid way to close out the period.

So, to sum it up: if you're experienced, you live for Friday, July 24th. That 16 ft swell with offshore wind is the stuff of legends. For the rest of us, the glassy Saturday afternoon on July 18th or the clean Thursday morning on July 23rd are your best bets. Stay safe out there.

Rusty.
