Marengo Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s take a look at the next couple of weeks at Marengo.

We’ve got a solid run of surf coming up, but it’s a bit of a mixed bag with the wind. The first few days are rideable but not perfect, then we get a real standout towards the end of the first week and into the second. The water is sitting at 57.6°, which is pretty much normal for this time of year.

Monday, August 3rd kicks things off with a 4.3 ft SW swell, period around 14 seconds, and a moderate offshore wind from the W. The combined energy is moderate (913). It’s clean, but not huge. The afternoon picks up a bit to 6.6 ft from the WSW with a 13-second period, and the wind stays fresh offshore. The energy jumps to strong (2361), but there are some rain showers around. It’s a good start.

Tuesday, August 4th sees the swell push up to 11.5 ft from the WSW with a 12-second period in the morning. That’s solid, but the wind is cross-offshore, and it’s a fresh breeze. The energy is very strong (4613). This is getting into bigger territory – over 8 ft, so it’s for experienced surfers only. The afternoon drops back to 8.2 ft from the SW with a moderate breeze, still cross-off. Clean, but the tide might be a factor.

Wednesday, August 5th is a tale of two halves. The morning has a 7.5 ft SW swell with a 14-second period, cross-offshore wind, and strong energy (2720). The afternoon is the real gem here: the wind swings to a light offshore from the WSW, the swell drops to a cleaner 3.6 ft from the SW, but the period is still a lovely 14 seconds. The energy is moderate (966), but with that light offshore wind, it’s going to be glassy and perfect. That’s the pick of the early week for a longboard or a funboard.

Thursday, August 6th and Friday, August 7th are smaller. Thursday is tiny with 2.3 ft to 2.6 ft, long period (16 seconds) but weak energy (318-354). Not worth paddling out. Friday morning has a 4.6 ft SW swell, light breeze, and clean conditions. The energy is moderate (1108). It’s a nice little window, but the swell is long-period, so it might be a bit walled-off at the beach, but for a point break like this, it should be lined up.

Saturday, August 8th is a write-off. The wind is howling from the NNW at 15.5 mph, crossing the swell, and the surf is a jumbled 4.3 ft to 3.9 ft. The energy is weak (500-800). The comment says "poor surf conditions" – don’t bother.

Sunday, August 9th is also poor. Strong breeze from the SW at 28 mph in the afternoon, with a 4.9 ft WSW swell. That’s a messy, blown-out situation. The morning is also cross-shore and messy. Hard pass.

Now, here’s the big one. Monday, August 10th. This is the standout. The morning shows an 11.5 ft SW swell with a 16-second period, light offshore wind from the WNW, and the energy is exceptional (6966). The description says "exceptional surf conditions for expert surfers." This is a serious swell. The afternoon is still 9.8 ft with the same wind and a 16-second period, energy at 4493. This is a groundswell of the highest order. If you’re an expert, this is your window. The long period is perfect for a reef/point setup like Marengo. The wind stays light and offshore. This is the best on offer.

Tuesday, August 11th drops back to 5.9 ft in the morning, then 7.5 ft in the afternoon with a massive 19-second period. That’s an incredibly long period, so the sets will be far apart but powerful. The energy is strong (3873). Still clean, but the wind is a moderate cross-off from the NNW.

Wednesday, August 12th and Thursday, August 13th continue the run. Wednesday has a 7.2 ft to 7.5 ft SW swell with a moderate offshore wind, excellent for experienced surfers. Thursday, August 13th afternoon is another standout: an 11.5 ft SW swell, 17-second period, and a moderate offshore wind. The energy is through the roof at 10624. That’s another exceptional day for experts only.

Friday,
