Marengo Surf Forecast and Surf Report

Alright folks, Rusty here with a long look at what’s on the cards for Marengo (reef and point). Let’s get into it.

Right now, things are flat and messy. The start of the period is a write-off with poor quality surf and a fresh cross-shore wind from the north at 19 mph making a mess of things. You won't want to bother with a paddle for the first day. After that, we’ve got a bit of a wait, but it won’t be long before the ocean wakes up.

Come Sunday the 12th, it starts to get interesting. Early morning, we’re looking at a 7 ft swell from the WSW, with a fresh offshore wind from the WNW at 22 mph. The waves will be clean, but this is already pushing into expert-only territory. By the afternoon, the swell jumps to a massive 20 ft, still with strong offshore wind. The combined swell energy is a staggering 13,442, so this is serious power. Only for the most experienced crew, and even then, paddling in will be a battle. Monday the 13th stays huge – 21 ft from the WSW with a very long 15 to 16-second period, meaning groundswell of the highest order. Combined energy hits 24,196 – that’s a lot of water moving. This break can handle it, but it’s not for the faint-hearted. The reef and point setup might make it work, but for most, it’ll be a tow-in or a spectator day.

The standout of the whole period, if you ask me, lands on Wednesday the 15th and Thursday the 16th. By Wednesday morning, the swell has dropped to a much more manageable 8 ft from the SW, but it’s still got grunt with a 14-second period (combined energy 2,114). The wind is a light offshore from the WNW at just 6 mph. This is clean, powerful, and perfect for experienced surfers. The water temp is 59°, about 2° warmer than average for this time of year – a nice little bonus. Thursday the 16th is even sweeter. The swell is 5 ft from the SW, but the wind goes to absolute glass in the afternoon – 0 mph from the west. Expect clean, lined-up waves that will have a bit of push from that 14-second groundswell. It’s not huge, but the quality will be through the roof. Crowds can be possible here, but on a day like that, any crowd will be a happy one.

Friday the 17th is another gem. Swell holds around 6 ft from the SW with a very long 16-second period, and the afternoon turns glassy with a light breeze from the NE. Combined energy is 1,633 – solid, fun, clean surf. This is the kind of day you call in sick for.

The following week has more action. Monday the 20th brings a building swell again, hitting 15 ft from the WSW by the afternoon, with moderate offshore wind. That’s expert territory, combined energy of 9,746. Then Tuesday the 21st stays big in the morning at 13 ft before dropping off. Wednesday the 22nd has a nice 7 ft from the SSW with glassy afternoon conditions – that’s a good one for a solid session. By the 24th and 25th, the swell drops back to the 5 ft to 7 ft range, but the winds get a little trickier, with cross and cross-onshore breezes. Still surfable, but not as clean as the earlier days.

Overall, the absolute best on offer is Wednesday the 15th through to Friday the 17th. That’s the sweet spot: clean, decent-sized, and with that long-period swell making for proper waves. After that, there are more windows of good surf, but those mid-July days are the ones to circle on the calendar.

Rusty.
