Marengo Surf Forecast and Surf Report

Alright, Rusty here. Let's have a look at what’s cooking for Marengo over the next couple of weeks. The water temperature is about average for this time of year, nothing wild.

Right off the bat, Monday the 7th is pretty weak with small, messy 3ft SW swell and a cross-off wind, only a moderate energy (469). Not worth paddling out. The afternoon gets a bit bigger at 6ft but the period drops to 8 seconds – short-period, crumbly stuff. Energy picks up (1048) but still a marginal call.

Now, Tuesday the 8th is where things start to look interesting. The morning brings a clean 4ft SW groundswell with a long 18-second period and a clean offshore wind. The energy is solid (1272) and conditions look very good. The afternoon gets even better: 6ft SW swell, still that long 17-second period, offshore wind, and pumping energy (1774). This is excellent for experienced surfers.

Wednesday the 9th sees the swell absolutely jack up. Morning has a 13ft SW swell with a 16-second period and cross-off wind, but the energy is massive (13095). Afternoon pushes 15ft SW at 18 seconds, energy off the charts (20693). This is too big for anyone but the most experienced, and even then, it’s a beast. For most, it's a watch-and-wonder day.

Thursday the 10th drops back a bit to 12ft SSW and 10ft SSW with moderate energy (5702, 4312), still big and cross-off winds. Friday the 11th is much more manageable: 7ft to 7ft SW groundswell (14-15 secs), light cross-off breeze, clean, and strong energy (1736-2037). This is a solid, powerful day for the crew who know what they’re doing.

The real standout comes on Saturday the 12th morning. The swell is a clean 6ft from the SW, a long 15-second period, and the wind goes absolutely glassy. The energy is still high (1667) and the conditions are perfect – offshore, glassy, just beautiful. The afternoon gets a light cross-on breeze and drops off a little.

After that, the surf takes a dive. Sunday the 13th and Monday the 14th are poor – small, weak, and windy. Tuesday the 15th brings it back with a punch: 10ft SW at 14 seconds in the morning, 8ft SW at 15 seconds in the afternoon, both with solid offshore winds and big energy (3128, 3109). Excellent for experts.

Wednesday the 16th is another cracker: afternoon session has an 12ft WSW swell, 14-second period, offshore wind, and huge energy (5688). This is one of the best on offer in the whole forecast. Thursday the 17th drops back to average, and Friday the 18th sees an 12ft SW swell with cross-off wind and 11-second period – a bit jumbled.

Saturday the 19th has a consistent 7ft SW with offshore winds, but the period is shorter (11-12 seconds). Sunday the 20th is a write-off with strong winds. Monday the 21st has a 7ft SW groundswell (15 seconds) but a cross-on wind messes it up. Tuesday the 22nd offers a 6ft SW at a long 17-second period with a light cross breeze, energy (1774), but not quite clean.

If I’m calling the standouts, it’s the Tuesday morning session on the 8th for a very good clean long-period swell, and the Saturday morning on the 12th – glassy conditions and a solid 6ft groundswell is as good as it gets for the crew. Keep an eye on Wednesday the 16th afternoon for the big-wave specialists.
