El Mongol Surf Forecast and Surf Report

Alright, Rusty here. Let's check out what's cooking at El Mongol.

It's a proper mixed bag over the next week and a half. The first few days are small and average, but the real juice is building later. Don't bother rushing out tomorrow.

Saturday, September 12th starts off weak with a 2ft NW swell. The combined energy is a measly 76, so there's nothing pushing through. It's clean with light winds, but the surf is poor. The afternoon is a bit better with 108 energy, but still just ordinary.

Things change on Sunday morning, September 13th. The swell jumps to 5ft from the NW with a period of 12 seconds, giving us a decent combined energy of 608. What makes this a standout is the offshore wind – light and clean from the ESE. This is the first real highlight. The wave quality is good and it's consistent, so get out there early. Sunday afternoon holds a 5ft NNW swell with 658 energy and gentle cross-off winds, still a great window.

Monday the 14th drops back to a 4ft NW swell (277 energy) in the morning, which is clean but nothing special. The afternoon is a step down again.

Tuesday the 15th is a write-off. Onshore and cross-onshore winds, short-period junk. A day to do something else.

Wednesday the 16th is a funny one. The morning is dead glassy, zero wind, with a 4ft NW swell (263 energy). It's surfable but ordinary. The afternoon is cross-onshore and marginal.

Thursday, September 17th morning is a true standout. We get a 6ft NNW swell with an 11-second period and a huge combined energy of 709. The wind is glassy from the SSW. This is the best we've seen so far – very good wave quality, consistent, clean. The afternoon gets a bit bumpy.

Friday, September 18th morning is another absolute beauty. A 6ft NNW groundswell (12-second period) with a massive 765 combined energy and dead calm, glassy conditions. This is primo. The afternoon swell pushes to 6ft NNW with 1027 energy, but it gets a light cross-shore wind giving it a bit of texture. Still a great day.

The swell stays in the 5ft to 6ft range through the weekend of the 19th and 20th, but the wind is a bit messier – onshore and cross-onshore. It's still surfable but not the peak.

Monday, September 21st morning is another cracker. A 5ft NNW swell with a 13-second period and 863 combined energy. The cross-off wind from the east is light and clean. That's a proper session.

The following week sees the swell drop a little, with 4ft to 5ft on offer, but the winds are good again. Tuesday the 22nd is clean, and Wednesday, September 23rd morning is glassy with a 5ft NW swell and 503 energy. Consistent and clean.

Then, the real fire comes in on Friday, September 25th. The morning delivers an 8ft NW groundswell with a 14-second period and a staggering 2425 combined energy. That is excellent surf, but it's only for experienced surfers. The afternoon holds a 7ft NNW swell with 1741 energy. This is the biggest and most powerful swell of the whole forecast. For the experts, this is the one to aim for.

The last few days of the month see the swell ease back to a fun 5ft to 6ft range.

The water temp is about average for the time of year.
