Marengo Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on tap for Marengo. This is a reef and point set-up that handles a fair bit of swell, but you gotta pick your moments. The water’s sitting at 57°, which is about average for this time of year, so nothing weird there.

Straight up, the first couple of days are small but surfable. Monday the 24th sees a clean 5 ft SW swell with 14-second period and cross-off wind. It’s a gentle start, but the energy is there at 898, and it’ll be a nice session for a beginner or someone wanting to stretch the arms. Not a standout, but a solid entry.

The next few days drop off a bit. Tuesday and Wednesday are smaller, around 4 ft to 5 ft, but the wind stays cross-off and sometimes glassy. Nothing to write home about. Then Thursday the 27th goes glassy with a tiny 2 ft to 3 ft SW swell – that’s a longboard or cruise session, but it’s clean as a whistle.

Now, Friday the 28th is where it starts to get interesting. We’ve got a 5 ft SW swell with a seriously long 18-second period, and the energy jumps to 1518. That’s a proper groundswell. The wind is cross-off, so the reef and point will handle that long-period energy beautifully. This is the first real standout for competent surfers. It’s not huge, but the quality is there.

Saturday the 29th and Sunday the 30th stay clean with glassy mornings and small to moderate SW swell, good for a relaxed paddle. But the real firecracker comes on Monday the 31st. That morning, it’s dead calm, glassy, with a 8 ft SW swell at 19 seconds. The energy is 3845 – that’s a powerful, solid groundswell. This is for experienced surfers only. The point will be lining up beautifully if you know what you’re doing. Crowds are possible here, so get in early.

Tuesday the 1st of September stays clean with offshore wind and a dropping 5 ft SW swell, still decent. Wednesday the 2nd is okay but gets a bit messy in the PM with onshore junk.

Then hold onto your board. Thursday the 3rd of September afternoon sees a massive 15 ft WSW swell with 13-second period and clean offshore wind. The energy hits 7798 – that’s ‘exceptional for experts’ territory. That is not for the faint of heart. Only the most experienced should even think about paddling out. This is the second true standout, but it’s massive.

Friday the 4th is still big, around 13 ft dropping to 8 ft, with decent wind. The rest of the first week of September stays bumpy and big, with a 13 ft swell on the 6th and then a howling 55 km/h cross-off on the 7th with an 18 ft swell (energy 20804) – that’s just insane. That’s not surfing, that’s survival. The 8th has a 13 ft SW swell with 18-second period and fresh offshore wind, but it’s for experts only.

So, the long story short: if you’re not an expert, your window is this week and early next week. The absolute best on offer is Monday the 31st of August for a big, clean, lined-up groundswell, and Thursday the 3rd of September afternoon for the truly brave. The rest of the time, it’s either small and clean or dangerously big. Respect it.

Stay safe out there.
