Marengo Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s cooking.

We’ve got a bit of a slow start, but the first real chance to get wet is Monday morning, July 27th, at Marengo. It’s a reef and point setup, fairly exposed to the swell, and it's a beginner-friendly spot. The water is sitting at 58°, which is about average for this time of year, so nothing crazy there. The morning session is a bit marginal, with a 4ft swell from the SW, period at 11 seconds, and a cross-off wind from the NNW at 9 mph. It’s clean, but the energy is moderate (415). Not a standout, but it’s a start.

The real story starts to build on Monday afternoon. The swell picks up a touch to 4ft, and the period stretches out to 13 seconds from the SW. The energy jumps to a moderate 718, and the wind stays clean. It’s a solid session, but the main event is still a day away.

Now, Tuesday, July 28th, is where things get serious. The morning is clean but the wind is a fresh 19 mph from the NW, making it a bit of a wrestle. The swell is 5ft from the SW, period 16 seconds, and the energy is strong at 1017. That’s a long-period groundswell, and at a point and reef break, it’s going to line up beautifully. But the real firecracker is Tuesday afternoon. The wind swings offshore from the WNW at 22 mph, the swell pushes to 6ft, and the energy jumps to a very strong 1547. The period is 15 seconds. This is the best window of the first week. The conditions are clean with a fresh offshore breeze. For a beginner-friendly spot, 6ft is on the edge of being too big, but for anyone with a bit of experience, this is a ripper.

Wednesday, July 29th, is for the brave. The swell hammers in at 15ft from the SW. Morning sees a strong breeze at 25 mph from the SW, cross-off, and the energy is a massive 15660. That’s a very strong, powerful swell. The period is 16 seconds. This is a full-on, expert-only day. The afternoon eases slightly with a 19 mph wind, still clean, but the swell holds at 15ft. This is not a day to be learning. It’s a spectacle.

After that, the swell drops back. Thursday, July 30th, has a clean morning with offshore wind from the WSW at 12 mph, and a 5ft swell from the SW (period 13 seconds, energy 1013). It’s a good, manageable day after the chaos. Friday, July 31st, is smaller but still clean, with a 4ft swell and light offshore winds in the morning. Saturday, August 1st, is the smallest of the run, with a 3ft swell from the SW, but the period is a very long 17 seconds. The energy is moderate (701), but the wind is light and cross-shore. It’ll be a bit of a slow, lully day, but the waves will have shape.

Looking into the second week, the standout is Monday, August 3rd. The morning is a big one: 13ft from the WSW, period 14 seconds, and a strong 7612 energy. The wind is offshore from the W at 16 mph. This is for experts only. The afternoon is cleaner but smaller, at 6ft. After that, the swell settles into a more consistent 4ft to 5ft range through Tuesday and Wednesday, with clean conditions. Thursday, August 6th, gets a bit choppy with a cross-on wind, and Friday, August 7th, is a write-off with onshore winds. The weekend of August 8th and 9th is small and a bit messy, with the swell staying around 4ft to 4ft and cross-onshore winds.

The best of the best? No question, it’s Tuesday afternoon, July 28th, and Wednesday morning, July 29th. Tuesday afternoon is the sweet spot for a strong, clean, long-period swell at a manageable size (6ft). Wednesday morning is the big one, but only for the hardcore crew. If you want a more relaxed standout, the Monday morning, August 3rd session is a promising long-range call, but keep an eye on the wind.

Rusty, out.
