Marengo Surf Forecast and Surf Report

Alright surfers, Rusty here. We’ve got a mixed bag coming our way over the next couple of weeks, but there are a couple of windows where Marengo will absolutely turn it on. Let’s get into it.

This forecast is all about Marengo, a reef and point set-up. It’s a beginner-friendly spot that’s fairly consistent and gets pretty exposed to the swell. The water temp is sitting about average for this time of year, so nothing too wild there.

We kick things off with a bit of a wait. The surf coming in on Tuesday the 15th is big, with swell heights around 15 ft and a solid 13-second period from the SW. The combined energy is huge (8827), but honestly, with a fresh cross-off breeze at 19 mph, it’s not going to be that clean. It’s a bit of a beast, and the conditions are marginal. Wednesday the 16th is much the same story: big 10 ft SW swell, still a bit windy, and the tide might mess with the quality. It’s not the best time to paddle out unless you’re really keen on big, windy waves.

Now, things start to clean up on Thursday the 17th. We’ve got a 7 ft SSW swell with a 14-second period, but the wind swings offshore from the WSW at 9-12 mph. That’s the good stuff. The combined energy is still significant (1644), and the forecast calls for excellent conditions for experienced surfers. This is a definite standout, but remember, with 7 ft waves and that long period, it’s a proper groundswell that will be firing down the point. It might be a bit much for the beginners, but for the rest of you, this is the window to clear your schedule.

Friday the 18th keeps the fun going with a similar 7 ft SW swell and a very long 17-second period. The wind is light and cross-off, so the waves will be clean and lined up. The energy is high (3326), and it’s another day of excellent conditions. This is your second standout of the first week.

We drop off a bit over the weekend. Saturday the 19th sees the swell drop to 4 ft, and Sunday the 20th starts small and windy before a massive pulse hits Sunday afternoon with a 16 ft WSW swell. That is huge, and with a fresh offshore wind, it will be a wall of water for experts only. The energy reading is through the roof (8122). For most of us, this is a "watch from the cliff" day.

The following week is a bit of a mixed story. Monday the 21st and Tuesday the 22nd have moderate to solid swell (7 ft to 10 ft), but the winds are a problem, turning onshore and choppy. Not worth the drive. We get a few smaller, cleaner days around Wednesday the 23rd and Thursday the 24th, but the swell is tiny.

Here’s the real gem for the second week. Keep an eye on Friday the 25th. The morning is looking glassy with a 5 ft SW swell and very light winds. It’s going to be clean as a whistle. Then, Saturday the 26th is looking absolutely prime. The morning has a 6 ft SW swell with a 19-second period, and it’s clean. But the afternoon? It goes completely glassy with a 10 ft SW swell and a 19-second period. That’s a massive, long-period groundswell with zero wind. The energy reading is massive (5766) and the forecast says excellent conditions for experienced surfers. That afternoon session on Saturday the 26th is the best call of the whole forecast. It’s still a week and a half away, so don’t hold me to it, but if it comes together, it will be a day to remember.

After that, the last few days of the month have some clean but smaller surf, with a 5 ft to 5 ft SW swell and offshore winds. A nice way to finish the run, but not the headline act.

So, to wrap it up: the first real standout is Thursday the 17th and Friday the 18th for solid, clean waves. But the absolute best on offer is that Saturday afternoon on the 26th of September. Mark it on the calendar and hope the forecast holds.

Rusty.
