Marengo Surf Forecast and Surf Report

Alright folks, it’s Rusty here, and I’ve been staring at the charts for our local patch – Marengo. This is a reef and point setup that can handle a bit of size, and it loves a good SSW swell. The water temp is sitting at 58°, which is pretty much what you’d expect for this time of year, nothing weird going on there.

The next few days are going to be a proper ride. The swell is big and the wind is offshore, so if you’ve got the skill level, Friday the 24th is your day. We’re talking a solid 16 ft of SW swell with a 15-second period, so the energy is pumping (16885). The wind is a clean offshore W breeze, but it’s a fresh 15–19 mph, so it’s going to be a workout just getting out there. This is for experienced surfers only – 5 ft is already pushing it for beginners, and 16 ft means you better know what you’re doing. The waves will be lined up, but the paddle out is a mission.

Saturday the 25th is still solid, but the swell starts to ease. You’ll find 13 ft on Saturday morning and 12 ft by the afternoon, still from the SW with a 12-second period. The offshore wind holds, so it’ll be clean. The energy is still significant (7145), but it’s a step down from the peak on Friday.

Then Sunday the 26th is a real standout. The swell drops to 10 ft, but it’s still a long-period SW groundswell at 11 seconds. The wind is a lighter offshore W breeze at 12 mph. Conditions are described as excellent for experienced surfers, and I’d call this the best balance of size and workability. The combined energy is still strong (2858), and the sea state is clean. If you’re looking for a big day that isn’t as terrifying as Friday, this is the one.

We hit a lull after that. Monday and Tuesday see the swell drop right off to 4 ft–5 ft, with the wind shifting cross-offshore. The energy is weak (down to 404 on Monday). Wednesday the 30th sees a bit of a pulse back with a 8 ft SW swell and a beautiful 15-second period. The wind is a gentle offshore WSW breeze, so it’s clean and glassy. This is a great window for a more relaxed session with the energy back up (3093). The weekend of the 1st and 2nd of August is a big one. Saturday the 1st has a 12 ft SW swell in the morning, but it’s cross-offshore. The real standout is Saturday afternoon: a 8 ft SSW swell with a 16-second period. The energy is massive (7147) and the wind is light. This is a rare, powerful groundswell that will be drawn into the point. We’re looking at exceptional conditions for experts. Sunday the 2nd holds 10 ft from the SW with a very long 18-second period, but the wind is light cross-shore, so it won’t be as perfect. That long period groundswell might make it a bit too straight for a beach break, but at a reef and point like Marengo, it’s going to produce some grinding, set waves.

After that, the energy trails off. From the 3rd of August through the 8th, the swell is smaller and the wind is mostly cross or onshore. The energy drops right down (under 1000 most days), and conditions are described as poor. It’s a quiet end to the outlook.

So, to wrap it up: the absolute best on offer is the afternoon of Saturday the 1st of August – that 8 ft SSW groundswell with a 16-second period and light wind is a proper dream scenario for the point. My second pick is Sunday the 26th of July, for the cleanest, most manageable big swell of the first week. Get amongst it.

Rusty.
