Marengo Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s shaping up for Marengo.

We’ve got a solid run of swell headed our way, but it kicks off with a bit of a raw Saturday morning. The 22nd of August starts with a chunky 16ft SW swell at 14 seconds, but that 16 mph WSW wind is blowing straight offshore – which is good for shape, but that’s a lot of ocean moving. The combined wave energy is at 13588, so there’s plenty of grunt. This is expert territory, no two ways about it. The water temp is 57°F, which is about normal for the time of year, so nothing unusual there.

The standout window really opens up later that afternoon and into Sunday. Saturday afternoon the swell drops to a still-serious 10ft from the SW at 15 seconds, but the offshore wind holds at 16 mph, so it’s powerful and clean. Then Sunday the 23rd is the real gem. The morning has a clean 6ft SW swell (14-second period) with a light cross-offshore breeze from the NNW at 6 mph. By Sunday afternoon, it goes glassy – wind is dead calm from the SW at 3 mph, and the swell holds at 7ft SW at a very long 16 seconds. That long period means the waves will have real push and shape, and with zero wind, it’s going to be pure, clean lines at this reef and point. Crowds are possible here sometimes, so get on it early.

Through next week we see the size drop. Monday the 24th is a nice, manageable 5ft SW swell with clean conditions and light breezes – good for beginners and intermediates. Tuesday the 25th goes glassy again in the morning with a 5ft SW swell and absolutely no wind. It doesn’t get much better than flat-calm conditions and waist-to-chest-high waves.

The surf stays fun and clean through midweek, with sizes ranging from 3ft to 4ft. By Thursday the 27th, it gets small – 1ft in the morning – borderline for a paddle. But it picks back up Friday the 28th with a 6ft SW swell at a very long 17 seconds and clean cross-offshore winds. That longer period means the reef and point setup at Marengo will really shine.

As we move into the first days of September, we’ve got another pulse. The 1st of September sees a 7ft SW swell at 16 seconds with light cross-offshore breezes – solid, powerful, and clean for experienced surfers. The 6th of September is a warning: Sunday morning shows a massive 25ft SW swell at 16 seconds, combined energy of 37916, and it’s just too big for this break. That one is for experts only, and even then, caution is the word.

Overall, the best of the best is Sunday the 23rd of August – glassy, long-period groundswell, and clean. After that, Tuesday the 25th morning is the other standout for pure, glassy fun. Don’t sleep on the first week of September either, especially the 1st.
