El Mongol Surf Forecast and Surf Report

Righto, Rusty here. Let's have a look at the slate for this stretch.

We're looking at a pretty bleak run for the next couple of weeks, to be honest. The first recommendation we get isn't until Thursday the 13th of August, so there's a long gap of a few days with absolutely nothing worth paddling out for. The overall energy is weak, and the conditions are mostly messy.

The only real standout window pops up on Thursday, 21 August, with a proper pulse of swell. It's over a week away, so keep that in mind, but it's the one to circle on the calendar.

El Mongol (reef) – The early part of the period is a write-off. Small, weak swell with cross-shore winds and barely any energy (combined swell energy often under 100). Tuesday morning the 11th looks glassy but with a tiny 2ft swell and a short period of 8 seconds. It's not doing anything.

Then on Thursday 13 August morning, we finally get something surfable. The swell is still small at 2ft from the WNW with a period of 12 seconds – that's a bit of groundswell, which is good for this reef. The wind is glassy. The wave comment says "surfable waves but very ordinary conditions" and the combined energy is 102 (weak to moderate). It's not pumping, but it's the only clean-ish window in the first week.

Things stay small and average right through until the 20th, with mostly cross or cross-onshore winds and energy that rarely breaks 100.

Then comes Friday 21 August. This is the one. We've got a significant jump. The morning shows a 6ft swell from the NNW with a period of 11 seconds – that's proper groundswell with decent energy. The combined energy is a whopping 1273, which is strong. The wind is light and cross-onshore from the west, so it'll be a bit textured. This is a solid, punchy reef wave. 6ft is getting up there, so it's more for experienced surfers, especially with that longer period making for power. The afternoon builds to 7ft from the same NNW direction, period 10 seconds, but the wind swings onshore from the NNW and there's light rain. The energy stays high at 1094. That morning session is definitely the pick of the entire 16 days.

Saturday the 22nd drops back to a smaller 4-4ft, with glassy conditions in the afternoon, but the energy is moderate (201-277). It's still surfable but nothing compared to Friday.

Overall, a long dry spell, then one solid day that could be a ripper if the forecast holds. The water is about average for the time of year.

Rusty.
