Marengo Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s take a look at what’s on the cards for Marengo over the next couple of weeks.

The first real action kicks off Monday morning, 3 August. We’ve got a solid 4.3 ft SW swell rolling in with a long 14-second period, and the wind is blowing offshore from the WNW at 15 mph. That’s clean, lined-up surf with moderate wave energy (913) – a nice way to start the week. Monday afternoon builds a bit, but the swell jumps to 9.8 ft from the W with a shorter 9-second period, and the wind stays fresh offshore. That’s a lot of power (2499) but the shorter period makes it a bit unruly – better for experienced surfers only.

Tuesday, 4 August, is still big but the wind swings cross-offshore, which takes the edge off the perfection. 9.8 ft SW swell at 11 seconds on Tuesday morning, dropping to 8.2 ft in the afternoon. The energy is still high (3542 and 2420), but it’s not the cleanest.

Wednesday, 5 August, is where it starts to look good again. Morning has 5.6 ft SW at 10 seconds with a gentle cross-offshore breeze – clean and fun. But the standout is Wednesday afternoon: 6.6 ft SW swell, 14-second period, and offshore wind at 12 mph. That’s excellent, powerful surf (2100) for experienced surfers, with long, clean lines.

Thursday, 6 August, drops right off – 2.3 ft to 3.0 ft with very long 16-second periods. The energy is weak (316-384), so it’s a small, slow day. Still clean, but you’ll be scratching for waves.

Friday, 7 August, is the pick of the first week. The morning is clean with 4.6 ft SW at 16 seconds, but the afternoon is glassy. The wind goes dead calm from the SW, and the swell is 3.9 ft at 15 seconds. That’s perfect, smooth conditions – you’ll be out there with a smile.

Saturday, 8 August, is a write-off. The wind cranks up from the N at 15 mph, cross-shore, and the surf is poor. Don’t bother.

Sunday, 9 August, recovers a bit with offshore winds again, but the swell is modest (3.6 ft to 4.3 ft) and the energy is moderate (489-711). It’s clean, but not exciting.

Now, the second week gets interesting. Monday, 10 August, sees a 7.2 ft SW swell at 17 seconds – that’s proper groundswell, with moderate energy (2794). The wind is cross-offshore, so it’s clean, but be aware that a 17-second period at a point/reef break like Marengo means the waves will be powerful, with long lulls between sets. Not for beginners.

Tuesday, 11 August, holds 5.9 ft to 5.6 ft SW swell, and Tuesday afternoon is a standout: offshore wind, 5.6 ft at 14 seconds, excellent quality for experienced surfers (1668).

Wednesday, 12 August, is another big day. 7.2 ft SW swell at 16 seconds in the morning, building to 6.9 ft in the afternoon with offshore wind. The energy is massive (3933) – clean, powerful, and demanding. This is expert territory.

Thursday, 13 August, is HUGE. The morning pushes 13.1 ft SW at 11 seconds (6480), and the afternoon hits 16.4 ft SW at 16 seconds (14143). That’s extreme energy. Only for the most experienced, and even then, it’s a serious challenge. The wind is cross-offshore, so it’s clean but massive.

Friday, 14 August, is a welcome drop – 5.6 ft to 5.2 ft SW at 12-13 seconds, with gentle offshore wind. Clean, fun, and manageable (915-935). Good for a lot of surfers.

Saturday, 15 August, is back to big. 9.8 ft SW at 19 seconds in the morning (6594) and 9.8 ft at 19 seconds in the afternoon with offshore wind (6433). That’s very long-period groundswell, and it’s excellent for experienced surfers, but that long period will make the waves jack up fast – best on the point.

Sunday, 16 August, is the biggest day. The morning is 14.8 ft SW at 17 seconds (18661) with cross-onshore wind – choppy and dangerous. The afternoon is 19.7 ft SW at 17 seconds (24532) – the forecast says it’s too big for this break. That’s a no-go for paddle surfing; this setup would be more interesting for kite surfers.

Monday, 17 August, is exceptional for experts. The morning has 14.8 ft WSW at 15 seconds (11599) with light cross-offshore wind, and the afternoon is 13.1 ft SW at 14 seconds (8193) – both clean and powerful. This is the true standout of the whole 16 days: big, clean
