Marengo Surf Forecast and Surf Report

Alright, let’s get into it. Rusty here, looking at the next couple of weeks for Marengo.

First up, we’ve got a solid, clean run of surf kicking off Tuesday, July 14th. The water temp is about average for the time of year, so don’t expect any surprises. The big story early on is the size. Tuesday morning (July 14th) is pumping – we’re talking a solid 18ft swell from the WSW, with a very long period of 16 seconds. That’s a serious groundswell, and with that much energy (19461), it’s powerful. A word of caution: at over 8ft, this is expert-only territory, and on a reef and point setup like Marengo, the long period will make for some fast, tapering lines – best for those who know what they’re doing. The wind is offshore and fresh, so it’ll be clean. Tuesday afternoon drops a bit to 13ft, still a big, powerful swell from the SW with a 15-second period (12069 energy). Still for experts.

Wednesday, July 15th, is the standout window. The swell eases to 13ft in the morning, but the wind is a clean offshore from the W at 12 mph, and the period is a solid 14 seconds. This is where the quality really shines. The energy is still very strong (8029), but it’s cleaner and more manageable for experienced surfers. Wednesday afternoon drops to 7ft, which is still a great size, and the wind remains offshore. The combination of a strong, long-period SW groundswell and clean offshore wind makes this the best session on offer.

Thursday, July 16th, and Friday, July 17th, keep the good vibes going with consistent 7ft to 6ft SW swell and light offshore or glassy winds. Friday afternoon (July 17th) is particularly noteworthy with a glassy surface and a 17-second period – that’s a very long, clean groundswell, perfect for the point. The energy is still significant (2358), and the conditions will be silky.

Saturday, July 18th, sees a drop in size to 4ft, but it’s glassy in the morning, making it a fun, clean option for all levels. After that, the surf gets smaller and weaker through the end of July, with a lot of days in the 2ft to 4ft range. The wind stays mostly cross-off, but the energy drops off a cliff. There’s a gap from around July 19th through July 22nd where the surf is mainly marginal and small.

Now, look ahead to the end of the month. Wednesday, July 29th, is a long-range standout to keep an eye on. The forecast shows a 6ft swell from the SW with a very long period of 18 seconds, and the wind is forecast to be glassy. That’s a promising setup, but it’s a long way out, so don’t bet the house on it yet. If it holds, that’s another morning of excellent, clean conditions at Marengo.

So, to wrap it up: the best surfing is definitely Wednesday, July 15th, and Friday, July 17th, for the combo of size, clean wind, and long-period groundswell. Tuesday morning (July 14th) is for the big-wave crew only. The rest of the window is small until that potential gem on July 29th.
