El Mongol Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s cut through the noise and get into what’s actually going on at El Mongol over the next couple of weeks.

First up, we’ve got a pretty slow start. The early part of September is a write-off for anything worthwhile – the swell is tiny, with heights barely scraping 3ft and combined energy is weak (55). It’s small, messy, and not worth worrying about. We’re looking at a solid gap of about three days with no real recommendations. Hold your horses.

Friday 5th September is where it finally wakes up. Saturday morning kicks off with a decent 5ft swell out of the NNW, and the period hits a sweet 13 seconds – that’s groundswell with proper shape and energy. The combined energy jumps to 808, which is a solid moderate range. Winds are light and cross-off from the east, so the faces will be clean. This is the first real standout. By the afternoon, it pushes up to 6ft (energy 958) and holds. This is solid intermediate territory – not for beginners, but the better surfer will find some proper lines on this reef.

Then Sunday 6th September morning is a beauty. The swell drops a touch to 4ft, but the period is still a long 11 seconds. The wind goes glassy out of the west – dead calm. Combined energy is 427. That’s a morning to have the place to yourself if the crowds aren’t on it. Clean, groomed, and punchy. The afternoon turns onshore, so get it early.

After that, the middle of the week gets a bit hit-and-miss. Monday and Tuesday have more size but the winds turn onshore or cross-on, making it lumpy. Not the best call unless you're desperate.

Wednesday 9th September is another true standout. The morning session sees a glassy calm, with 6ft of NNW groundswell at 11 seconds. Combined energy is 682. That’s clean, powerful, and lined up perfectly for this reef. The direction (NNW) is right in the sweet spot for El Mongol. This is your pick of the week, no question. Just be aware that the water temp is sitting at 69°F, about 2° above the norm for this time of year – pretty normal, nothing wild.

The second week settles down. From the 14th, we see smaller, cleaner waves. Monday 14th September offers 4ft from the NW with a long 12-second period and light cross-off winds. Energy is 355 – weak to moderate, but clean. It’s a “good” call, but nothing to get overly excited about. The 16th and 17th repeat this pattern: small, clean, but ordinary. Not a bad run, but the real magic is in that first weekend and Wednesday morning.

On the whole, El Mongol is consistent enough that this blank run won’t last – and it doesn’t. The first week has a couple of proper windows.

Stay salty.
