Marengo Surf Forecast and Surf Report

G’day, Rusty here, looking at the Marengo stretch over the next couple of weeks. We’ve got a bit of a slow start, but once the swell kicks in, there’s some serious size on offer, especially for the experienced crew.

Right now, nothing’s really happening. The first solid chance doesn’t roll in until the afternoon of Thursday the 10th of July, so you’re looking at a few days of flatness before that. Even then, Thursday the 10th afternoon is only showing 4 ft of SW swell with a long 15-second period, but the wind is light and cross, so it’s pretty weak overall. Not much to write home about.

The real action starts to build on Sunday the 12th of July. Sunday morning brings a 7 ft SW swell (13-second period) with a strong offshore wind from the west, but it’s blowing 25 mph—clean, but a mission to paddle into. The afternoon gets bigger, jumpin’ to 13 ft SW (13-second period), and the wind eases to 22 mph offshore. The combined energy is massive, but this is expert territory now. The break is a reef and point setup, which handles a long-period groundswell well, but 13 ft is no joke.

Tuesday the 14th of July is the standout, but it’s not for the faint-hearted. Morning and afternoon both see a massive 18 ft SW swell with a 16-second period, and the combined energy is off the charts. The wind is cross-off at 19 mph, so it’s clean, but the file says it’s too big for this break. This is strictly for experts, and even then, it’s a wild one. The water temperature is sitting at 59°, which is a touch warmer than the norm for this time of year.

After that, Wednesday the 15th of July is a sweet spot for experienced surfers. You’ve got an 8 ft SSW swell (15-second period) in the morning, with light cross-off wind, dropping to 7 ft in the afternoon. Clean conditions, solid energy, and the reef and point will handle that long period nicely. Crowds are possible at Marengo, so keep that in mind.

The week of the 22nd of July brings another highlight. Thursday the 23rd of July morning has a 8 ft SW swell (17-second period) with glassy conditions—that’s a big plus. The afternoon is the real gem: 15 ft SW swell (16-second period), clean with slight air, and the combined energy is massive. The file calls it exceptional for expert surfers, and I’d have to agree. The light wind makes it clean and inviting, but the size means it’s for the big-wave crew only.

Overall, the best on offer is Monday the 14th of July for sheer size and power, but it’s intimidating. For a more manageable but still high-quality session, Wednesday the 15th of July and Thursday the 23rd of July morning are your standouts. Keep in mind, the long-period swells (15-17 seconds) will break with more energy and longer lulls, which is ideal for the reef and point setup here.

Rusty out.
