El Mongol Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s cookin’ for this little slice of coast. We got one spot in the frame, and it’s gonna be a bit of a rollercoaster over the next couple weeks. There’s a real gem in there, but you gotta be patient.

Right off the bat, Saturday the 29th of August ain’t a waste, but it’s not the main attraction. You’ll find clean 5ft waves from the WNW at El Mongol, with the water temp sittin’ at a nice 70°, a touch warmer than normal for this time of year. That’s a sweet bonus. The wind is glassy, so the surface will be smooth, but the energy is moderate (335) and the period is a short 8 seconds, so the waves will be a bit lumpy and lack real drive. It’s surfable, but not the highlight.

Sunday the 30th is a bit of a bummer. The swell bumps up to 6ft from the NW with a slightly better 9-second period, but that onshore wind is gonna chop it up. It’s a “marginal” call all day, so I’d sit this one out.

Monday the 31st of August is where it gets real. Early morning is your first real standout. We got clean 6ft NW swell, and the wind is dead calm – glassy as a lake. The period stretches to 10 seconds, and the combined energy jumps to a solid 671. That’s moderate to strong energy, meaning the waves will have some proper punch. This is the best session of the first week, no doubt. The afternoon stays the same size, but a light cross-shore breeze will put a few ripples on it.

Tuesday the 1st of September is another morning-only show. The swell drops to 4ft from the NW, but it’s glassy again, and the energy is still decent at 333. It’ll be clean and fun for the early crew. The afternoon turns to poor conditions, so don’t bother.

After that, we hit a dry spell. From Wednesday the 2nd right through to Thursday the 3rd, the swell tanks. We’re lookin’ at waves under 3ft with almost no energy. There’s a tiny bump on Thursday morning with 3ft and glassy conditions, but it’s barely enough to get excited about. It’s basically a gap of two days with nothing worth paddlin’ out for.

Then, on Friday the 4th of September, we get the true standout of the whole outlook. This is the one to circle on the calendar. The morning serves up 6ft from the NNW with a very long period of 13 seconds – that’s real groundswell energy. The combined energy is a massive 944, which is strong. The wind is light and cross-offshore, so the waves will be clean and well-shaped. This is a reef break, and that long-period swell will love wrapping in here. It’s expert territory, but for those who can handle it, this is gonna be firing. The afternoon holds at 6ft with a 12-second period and similar clean conditions (877 energy).

Saturday the 5th of September keeps the momentum going. The morning is 5ft from the NW, clean and cross-off (717 energy), and the afternoon sees the swell kick back up to 6ft from the NNW with a 13-second period and a massive 1093 energy. That’s very strong. Another fantastic day, but note that the afternoon has a slight cross-off breeze that will keep it clean.

Things start to fade on Sunday the 6th. The swell is still 4ft from the NNW, but the wind swings cross-onshore, and the quality drops to marginal. Monday the 7th of September has a glassy morning with 4ft NW swell (436 energy) which is worth a look, but the afternoon turns ugly.

The second week is a bit of a slow burn. The swell stays small and inconsistent through Tuesday the 8th and Wednesday the 9th, with most days showing poor conditions. There’s a brief flash on Friday the 11th of September, where a very long-period 15-second NW swell arrives (4ft, 501 energy) in the morning, and 4ft (583 energy) in the afternoon. That could be a sneaky good session with clean, cross-off winds. It’s promising, but it’s a week and a half out, so keep an eye on it.

The weekend of the 12th and 13th of September looks marginal again, with onshore winds messin’ up a 4-5ft NW swell. Not worth planning around.

Bottom line: Monday the 31st of August morning is your first standout – glassy, solid, and clean. But the real champion is Friday the 4th of September, with that long-period NNW groundswell and clean conditions. That’s the one.

Stay wet, stay salty.
Rusty.
