Marengo Surf Forecast and Surf Report

Alright, let’s get into it.

The next couple of weeks at Marengo are a mixed bag, but there’s definitely some good stuff lining up if you’re patient. The opening days are a bit of a tease—there’s swell, but the conditions feel a little off, and the tide isn’t playing along. The real standout window looks like it’s shaping up around next weekend, with some proper groundswell and offshore flow. Keep an eye on the long-range calls, though—things are a little less certain out that far.

Starting Tuesday the 15th, we’ve got a solid 13.1ft swell from the southwest with a 14-second period, but it’s blowing 35 km/h southwest, cross-off. It’s clean, but the commentary says it’s marginal, and the energy is massive—8215—so it’s going to be big and unruly. Not the day for the faint-hearted. Water temp is 57.7°, which is a touch warmer than normal for this time of year, but you’ll still want a good wetsuit.

Wednesday the 16th drops a bit to 9.8ft, still SW, with a longer 15-second period. Wind is lighter, 20 km/h from the SSW, cross-off. Clean again, but still that "marginal" tag. Energy is still strong at 3590. This is more manageable than Tuesday, but the quality call is muted.

Thursday the 17th eases down to 6.2ft. Morning’s a bit cross-off, but the afternoon turns offshore from the WSW at 20 km/h. The comment flips to "expect very good surf conditions," but the score is still modest. Period is 14 seconds, so there’s some push. This feels like the start of the cleaner stretch.

Friday the 18th is interesting. Morning has 6.6ft from the SW, 17-second period—that’s a proper groundswell—but it’s cross-off. The afternoon though, that’s where it’s at: 6.2ft, 16 seconds, light WNW cross-off at 15 km/h, and the comment says "excellent surf conditions for experienced surfers." Energy is 1698, so it’s strong but not crazy. This is one of the better windows in the near term.

Saturday the 19th is smaller, 4.9ft in the morning, dropping to 4.3ft in the afternoon, with proper offshore wind from the WNW and W. Clean, but the energy’s dropping off—758 in the morning, 647 in the afternoon. It’ll be fun, but not the standout.

Sunday the 20th is a split personality. Morning is a bit of a dud—3.9ft, cross-off but 35 km/h from the NNW, and the score is zero. Then the afternoon is a big pulse: 11.5ft from the WSW, 12 seconds, with a fresh offshore W wind at 35 km/h. Energy jumps to 4584. The comment is still marginal, but that’s a lot of water moving. More for the experienced crew.

Monday the 21st is back down—5.9ft in the morning, 7.2ft in the afternoon, SW and SSW, cross-off but moderate breeze. Clean but still marginal calls. Energy is moderate.

Tuesday the 22nd is where it starts getting messy. 9.8ft from the SSW, 16 seconds, but the wind turns onshore—SE in the morning, E in the afternoon. It’s choppy and cross-onshore. Not worth the paddle unless you’re into a fight.

Wednesday the 23rd drops to 6.2ft, but the wind is light and cross-shore from the north. Clean-ish, but the energy is winding down. Marginal.

From Thursday the 24th through Friday the 25th, the swell fades to under 3.3ft, and the wind starts coming from the northeast—cross-onshore. Poor conditions, small waves. You’re looking at a flat spell here.

Then the second week picks up again. Saturday the 26th brings a new pulse: 6.9ft in the morning, 5.6ft in the afternoon, with a long 18-19 second period from the SW. Light offshore in the morning, fresh offshore in the afternoon. Energy is strong again—2714 and 3086. This is looking promising, but it’s still a week out.

Sunday the 27th is potentially the best of the run. 6.2ft in the morning, 7.9ft in the afternoon, SSW and SW, 16-second period, with moderate offshore flow from the WSW. The commentary says "excellent surf conditions for experienced surfers." Energy is solid at 2177 and 2785. This is the standout window—proper groundswell, offshore
