Marengo Surf Forecast and Surf Report

Alright, let’s get into it. The next couple of days look pretty quiet at Marengo, a reef and point setup that loves a solid SW groundswell. The water is sitting at 57°, which is pretty normal for this time of year.

Sunday the 23rd kicks things off with a good pulse. We’re looking at a 6 ft SW swell, long period around 14 seconds, and a light NW cross-off wind. Combined energy is strong at 2097. It’s not huge, but it’s clean and well-shaped. Best for experienced surfers, and the crowds are only sometimes an issue, so you might get a few ones to yourself. Sunday afternoon holds similar – 7 ft, 16 second period, glassy cross-off. Clean lines all day.

Monday the 24th drops a little to 5 ft, still a long 14 second SW swell, with a NNW cross-off in the morning. Energy reads 900 – moderate. Decent waves, but the afternoon gets cross and a bit messy. Definitely a morning session.

Tuesday the 25th has light rain and onshore wind in the morning – not great. But Tuesday afternoon turns it around: 4 ft SSW swell, 13 seconds, with a light offshore wind. That’s clean, fun little waves. Worth a paddle.

Wednesday the 26th and Thursday the 27th are small and a bit wind-affected – waves around 2 ft to 5 ft, but the wind is either cross-off or offshore, so it stays clean. Nothing special.

Now Friday the 28th is a real standout. Morning sees 6 ft WSW swell with a long 18 second period, WNW offshore wind. Energy hits 1663. Clean, powerful, lined up. This is the kind of day that makes you forget the work week. Afternoon stays solid at 5 ft, 16 seconds, still offshore.

Saturday the 29th holds a steady 4 ft, 14 second SW swell with offshore wind. Moderate energy, clean conditions – good for a long session.

Sunday the 30th is another big standout. Morning swell jumps to 8 ft SW with a 16 second period, combined energy a massive 2718. Offshore wind from the WSW. This is proper groundswell – powerful, clean, and only for experienced surfers. The afternoon is a touch smaller at 8 ft but just as clean.

Monday the 31st stays strong: 6 ft SSW, 15 seconds, light offshore wind. Clean and fun through the day.

Into September, Tuesday the 1st sees 6 ft SW swell, 15 seconds, with offshore winds in the afternoon. A good session but the morning is a bit messy. Wednesday the 2nd and Thursday the 3rd drop off quickly – small, weak, not worth hustling for.

Friday the 4th and Saturday the 5th are marginal. Small clean waves, but nothing to write home about.

Sunday the 6th brings a glassy morning with 5 ft SW swell – nice and clean for some cruisy rides. Afternoon picks up a long 16 second period swell, very clean.

Now, Monday the 7th of September – hold onto your board. We’ve got a monster 18 ft WSW swell with a 13 second period, combined energy an insane 11516. But the wind is howling at 22 mph, cross-off. This is massive, messy, and only for the absolute best or for those who like their kites. The afternoon gets even stronger with 16 ft and 25 mph offshore wind – hard to paddle into, extreme conditions.

Overall, the real gems are Sunday the 23rd, Friday the 28th, Sunday the 30th, and Monday the 31st. Best on offer? Friday the 28th morning for that long period offshore clean combo, and Sunday the 30th for the big, powerful groundswell.
