Marengo Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what's on the cards for the Marengo area. The water temp is sitting at 59°, which is about a degree and a half warmer than usual for this time of year. Nothing crazy, but you'll notice the difference.

Right now, we've got a little bit of a wait for the real action. The first few days are just too small to get excited about. Sunday morning the 19th is glassy with some clouds, but the swell is only 3ft from the SSW on a long 11-second period. It's clean, but there's just not enough push. The combined energy is weak (330). We'll see a similar story through Monday and Tuesday, with the swell picking up a little but staying very ordinary.

The real standout of this whole run kicks off on Thursday the 23rd. That afternoon, the wind goes fresh offshore from the WSW, and the swell jumps to a solid 13ft from the SW on a 14-second period. The combined energy is massive (9841). This is proper groundswell. This is expert-only territory, way over 8ft, and the long period means it will be better for the reef and point setup at Marengo than a beach break. It's going to be a beast, but you'll need to know what you're doing.

Friday the 24th is even bigger. The afternoon sees an 18ft SW swell (15473 combined energy) with fresh offshore wind from the W. This is another massive, expert-only day. The long period (14 sec) will keep it lined up and powerful on the reef and point.

Saturday the 25th is another big one. The morning has 16ft SW swell (11538) with a cross-off wind, but it's the afternoon that steals the show. The wind goes offshore from the W, and the swell is still a hefty 15ft (8673). This is described as exceptional for experts. The consistency is there, and the crowds are a "sometimes" thing here, so you might get some company if you're out there.

After the big weekend, Sunday the 26th is a welcome drop-off to a more manageable 6ft from the SSW with light offshore winds – clean and fun for those who aren't chasing the massive stuff. The combined energy is a moderate 944.

The following week gets messy. Monday the 27th is small and cross-off, and Tuesday the 28th is a write-off for surfing with a strong cross-shore wind and lumpy conditions. That afternoon, the swell jumps to 20ft, but it's a short-period WSW windswell (12062 energy) coming in with a cross-off wind. This setup is more interesting for the kite surfers than paddle surfers.

Wednesday the 29th has a clean 8ft swell in the morning with offshore wind – good for experienced surfers. The rest of the week into the start of August sees the swell hanging around the 10-13ft mark, but the wind is mostly cross-off, keeping the conditions ordinary. The combined energy stays strong (around 4000-5500), but it's not the clean, lined-up stuff we saw in the first week.

So, to wrap it up: if you're an expert, mark your calendar for Thursday the 23rd through Saturday the 25th. That's the heart of the biggest, cleanest swell. The 24th (Friday) afternoon looks like the absolute peak for size and conditions. For the rest of us, the Sunday the 26th is the best call for a cleaner, smaller session.

Rusty.
