Marengo Surf Forecast and Surf Report

Alright, let me tell you how it’s looking for Marengo over the next couple weeks.

Right now, we’ve got a solid pulse of south-west groundswell rolling in. The water’s sitting at 57° and that’s bang on average for this time of year, so no surprises there. The big story is a long-period, 18 second groundswell building out of the SW, packing a massive punch of energy — we’re talking a combined swell energy reading of 7452 (that’s strong to very strong). But that big, clean energy comes with a caveat right now: Wednesday afternoon the wind is a cross-off from the SW at 16 mph, which will keep the lineup tidy enough but it’s a big 12 ft swell. That size is well into expert-only territory, especially with that very long period that’ll make it lurchy and powerful at the reef-and-point setup here. Not one to mess with if you’re not on your game.

By Thursday the 10th, swell holds in the 10 ft range out of the SSW with 16 second periods. Morning looks cleaner with lighter cross-off winds. Still big, still only for experienced surfers. Crowds at Marengo can be around sometimes, but with this size, it’ll thin the pack a little.

Friday the 11th sees the swell drop to a more manageable 8 ft, period still at a nice 15 seconds. Morning glassy conditions with those light cross-off winds out of the SSW — this is where things start to look good for a decent session if you’ve got the skills.

Now, here’s the standout: Wednesday the 16th. Morning glass — dead calm with an SSE breeze, virtually no wind. We’ve got a 8 ft SW groundswell at 16 seconds and the combined energy is 4425 — still strong, powerful, long-period, groundswell. That means clean, lined-up waves on the point at Marengo. It’s still solid, so I’d say experienced surfers are going to have a cracker. After that, winds go cross-onshore in the afternoon and it gets a bit bumpy.

As we head deeper into the second week, things drop off. The weekend of the 13th and 14th fades to around 4 ft – 2 ft with periods dropping to 13 seconds. That’s weak, and by Monday the 14th afternoon the wave energy drops to just 190. Not worth paddling out. There’s a blank stretch there with barely anything rideable.

We do see a small rebound around Tuesday the 15th, with a 7 ft SW swell and 13 second period — but the combined energy is moderate at 1867. Winds stay cross-off and clean, and this makes the Tuesday morning session look okay for intermediates, if only for a few hours.

By the 20th we get another pulse of SW groundswell, 5 ft but with 16 second period: combined energy at 1163 — moderate — and light offshore NW winds. That Sunday morning looks like a nice mellow window for a mixed bunch, but it’s not going to hassle the Wednesday session as the top call.

Overall, the clear winner is Wednesday the 16th morning. Strong, glassy, clean groundswell. If you can make it, that’s your day.
