Marengo Surf Forecast and Surf Report

Alright folks, Rusty here, lookin’ at what Marengo’s got cookin’ for us over the next couple of weeks. We’ve got a solid run of waves comin’, but you gotta pick your moments—this ain’t a constant party, but there are some absolute ripper windows.

The pattern starts this Sunday, the 23rd of August, with a decent pulse of SW groundswell already in the water. We’re talkin’ a long-period 14 second swell at 6ft, with a massive 2097 combined energy—that’s serious power. It’s clean with a light cross-off breeze, but this is for experienced surfers only. Too much grunt for the groms.

Monday the 24th is a beauty for the average punter. The swell drops to a friendly 5ft from the SW, still with a nice 14 second period, and the energy is a moderate 898. Monday afternoon goes glassy with no wind at all. That’s the window for the intermediate crew to get some clean ones.

Tuesday the 25th gets a bit messy. Rain and a shifting wind mean marginal conditions, though there’s still some waist-high swell around. Not your best day.

Wednesday the 26th is a standout for the big dogs. The morning starts with a clean 5ft SW swell and a moderate offshore breeze, but the real fire comes in the afternoon. We’re talkin’ a 10ft WSW groundswell with a 13 second period and a combined energy of 3356. That’s a proper paddle, and it’s blowin’ offshore. This is expert territory, and it’ll be a sight to see.

Thursday the 27th gives you a breather in the morning with tiny 2ft surf, but the afternoon bounces back to 6ft from the WSW with light offshore wind and 1502 energy. Clean, punchy, and very surfable.

Friday the 28th is another cracker. Solid 6ft SW swell, 17 second period—that’s groundswell with serious travel—and a gentle offshore wind all morning. The energy is 1949. You’ll be gettin’ long, lined-up walls. This is the pick of the first week for a good all-round surfer.

Saturday the 29th keeps the run goin’. Clean offshore conditions again with a 6ft SW swell in the afternoon and 2109 energy. Sunday the 30th has a big morning with a 5ft SSW groundswell at 18 seconds and 2490 energy. That afternoon, though, hits 10ft from the SSW with 4881 energy, but there’s a note of caution in the data—tide could mess with it. Keep an eye.

Monday the 31st is solid: 8ft SW swell, 15 second period, light cross-off breeze, and 2409 energy. Another very good day for experienced surfers.

Now, we get a gap of a few days, but then the real monster arrives. On Tuesday the 1st of September afternoon, the ocean goes off. A 13ft WSW swell with a 14 second period and a combined energy of 8446. That’s exceptional, and it’s blowin’ moderate offshore. This is for experts only—the kind of day that gets the heart pumpin’.

The swell keeps pumpin’. Wednesday the 2nd is messy with cross-on wind, but Thursday the 3rd is a huge day. Morning hits 18ft from the WSW at 12 seconds, with a combined energy of 9680. That afternoon goes 20ft with a 14 second period and a staggering 18550 energy. It’s blowin’ a strong offshore at 25 mph. That’s a true big-wave day, only for the brave, and paddlin’ in will be a battle.

Friday the 4th of September is still pumping but more manageable: 12ft SW groundswell at 16 seconds with 5940 energy and clean offshore wind. Still expert territory, but slightly less chaotic.

After that, the surf settles. Saturday the 5th has 6ft clean waves, and Sunday the 6th drops to small 4ft with strong wind. Monday the 7th has 5ft but is a bit ordinary.

So, to wrap it up: for the average surfer, the standout window is Friday the 28th of August through Monday the 31st. For the big-wave crew, the true standout is Tuesday the 1st of September afternoon through Friday the 4th of September. Get on it if you can handle the juice.

Rusty.
