Marengo Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it for Marengo.

We’ve got a solid run of surf coming up, with the best action kicking off this Friday morning and stretching through to the end of the second week. The overall pattern is a sustained SW groundswell, with a few standout sessions that are going to be worth getting wet for.

The first real highlight slaps you right in the face on Friday, 31st July. Marengo is a reef and point setup, and it’s going to be working beautifully. The morning brings a clean 4ft SSW swell with a 12-second period. The wind is light offshore from the WNW, meaning the faces will be smooth as glass. The combined energy is moderate (544), so it’s got plenty of push for a beginner-friendly spot. The water is sitting at 58°F, which is right around the average for this time of year, so no nasty surprises on the temperature front.

Then Friday afternoon holds up just as well. The swell drops a touch to 4ft, but the wind swings to a light cross-offshore from the SW, keeping it clean. Solid.

Now, if you want the real standout of the whole forecast, look no further than Saturday, 1st August, in the afternoon. The swell jumps to 6ft from the SW, but the period is a massive 17 seconds – that’s groundswell with serious legs. The combined energy rockets up to 2787, which is strong. The wind is a light cross-offshore from the NNW. This is expert territory at 6ft with that long period. It’s going to be powerful, offering up some proper, lined-up waves at the point. This is the session to circle.

Sunday morning, 2nd August, still has a solid 6ft SW swell with a 16-second period, but the wind picks up to a moderate 12 mph cross-offshore from the north. It’s clean, but the breeze is there. The energy drops to 1510 (moderate).

Monday, 3rd August, brings a drop in size to 4ft in the morning, but the afternoon is the real story. You get a 7ft WSW swell with a 14-second period, and the wind goes straight offshore from the W at 9 mph. The energy is strong (2911). This is another one for the experienced crew.

The swell stays up through Tuesday, 4th August, with a 8ft SW swell in the morning (energy 2371), but the wind is a cross-offshore. The afternoon is a bit messier with a 16 mph cross-offshore. By Wednesday, 5th August, the swell drops right back to 2ft, but the period is a very long 19 seconds, and the wind is offshore. It’ll be clean but small.

There’s a gap of poor conditions through the middle of the second week. Friday, 7th August morning is a quick highlight: glassy conditions with no wind and a 5ft SW swell (16-second period, energy 1178). That’s a rare, perfect window, but it’s short-lived.

The real monster arrives on Monday, 10th August. The afternoon shows a massive 16ft WSW swell with a 17-second period. The combined energy is an enormous 15620. The wind is a moderate cross-offshore. This is not for the faint of heart – expert only, and even then, it’s going to be a formidable challenge. If you’re a beginner, stay well clear.

The tail end of the forecast, from Thursday, 13th August onwards, has a lot of energy but often with strong winds. Thursday morning has a 6ft SW swell (17-second period, energy 1977) with a moderate offshore from the W. That’s a solid, clean option. Friday, 14th August morning, is similar with a 8ft swell (19-second period, energy 4174) but with a fresh 19 mph offshore wind. Saturday, 15th August, wraps it up with a 6ft swell in the morning and a moderate offshore – very good conditions.

To sum it up: the best of the best is the Saturday 1st August afternoon session and the Monday 3rd August afternoon. Those are the ones you don’t miss. The crowds at Marengo can be present sometimes, so get in early for the peak windows.

Rusty.
