Marengo Surf Forecast and Surf Report

G’day, Rusty here, looking at the Marengo stretch over the next couple of weeks. The water temp is sitting pretty average for this time of year, so nothing to worry about there. The real story is a solid pulse of SW groundswell that’s gonna light things up, but you’ll have to sit through a few average days first.

We start off quiet on Friday the 10th with a 4ft SW swell, period hanging around 15 seconds, but it’s a cross-shore breeze and the energy’s only moderate (716). Not much to write home about. Saturday the 11th gets worse – a fresh breeze from the N with 3ft to 3ft SW swell, poor conditions, and the energy drops off (310). Sunday the 12th is where it gets interesting. A big 20ft WSW swell rolls in early morning, period 13 seconds, combined energy is a huge 13867 – that’s some serious power. The wind is offshore and strong, but this is only for experts. It’s a strong offshore breeze, so the face will be clean, but paddling into that size at a reef and point setup is no joke. By afternoon it’s still 12ft, still offshore, but the energy backs off (7048). Still a heavy day.

Monday the 13th and Tuesday the 14th keep the size up around 8ft to 12ft, with a very long period of 15-16 seconds. That’s proper groundswell, and at a reef and point like Marengo, that’s a dream – the waves will have shape and power, but the sets will be spaced out. The wind is cross-offshore, clean, but the energy is still strong (3227 to 5180). These are days for experienced surfers only.

Now, the standout that’s really got me buzzing: Wednesday the 15th. The swell drops to a more manageable 8ft in the morning, still that 15 second period, and the wind is light from the NW. Combined energy is 2296 – still strong but way more user-friendly. The description says “excellent surf conditions for experienced surfers” and I reckon that’s the pick of the run. Clean, powerful, and the crowd at Marengo can be “sometimes” busy, so expect a few bodies out there, but it’ll be worth it.

Thursday the 16th is a treat for the early birds – glassy conditions with a 4ft SW swell, 14 seconds. That’s a nice, clean, smaller wave for the intermediate crew. Friday the 17th also looks good, with 6ft in the morning and glassy by afternoon, that 16 second period still rolling in. The energy is moderate (1512) and the reports say “very good surf conditions.” Lovely.

After that, the run fades out a bit. Saturday the 18th and Sunday the 19th see the swell drop to 4ft and then 2ft, with poor conditions and a cross-shore breeze. The energy falls off a cliff (689 to 166). There’s a bit of a gap here with no real recommendations. Monday the 20th is poor, with strong offshore wind but only 4ft to 3ft. Tuesday the 21st picks up a little with 5ft, 13 seconds, and a gentle offshore in the afternoon (610), but it’s not a standout.

The back half of the window has a couple of promising blips. Wednesday the 22nd afternoon shows 5ft with a short 9 second period (819 energy) – that’s a bit of a messy windswell, but it’s clean. Then Thursday the 23rd morning is another one for the experienced crew: 6ft, 16 seconds, cross-offshore, energy at 1825. The afternoon gets chunkier with 8ft, 15 seconds, and a light breeze – that’s a solid session if you’re up for it. Friday the 24th has 8ft to 8ft SSW swell, but the period drops to 12-14 seconds and the wind is a moderate cross-offshore, making it a bit lumpy. Not the best.

Overall, the absolute best is Wednesday the 15th – 8ft SW, 15 seconds, light cross-offshore, and that classic reef and point shape. The Thursday 23rd afternoon is a close second, with 8ft and a very light breeze. Get on it, but don’t sleep on the glassy sessions on the 16th and 17th if you want something smaller.

Rusty.
