El Mongol Surf Forecast and Surf Report

Alright, folks, Rusty here. Let’s get straight into it. We’ve got a mixed bag ahead, but there are definitely some windows of fun surf to chase.

The water temp is sitting at 70°, which is a touch warmer than normal for this time of year – nothing radical, but a nice little bonus if you’re heading out.

The standout in this forecast is El Mongol, a consistent reef break that handles a swell from the NNW. It’s fairly exposed, so when the conditions line up, it pumps. The best of the bunch kicks off on Saturday the 29th of August. The morning shows a 5ft NW swell with an 8-second period, and the wind is glassy. That’s pure, clean conditions. The afternoon holds a similar 5ft WNW swell, also glassy. Combined energy is moderate around 376 and 327. This is the pick of the early period.

Sunday the 30th starts off well too – 6ft NW swell, 9-second period, and glassy conditions on the morning. That’s a solid session with moderate energy (457). The afternoon turns a bit cross-on, so get in early.

Coming into Monday the 31st, the morning glass again with a 6ft NW swell and a 10-second period. That’s a longer period groundswell, which means more energy and better shape, but it’s best at a reef like El Mongol. Combined energy is strong at 666. This is a quality window.

We then hit a bit of a lull. From the 2nd of September through to the 5th, the swell really drops out. Heights fall below 3ft, and while the winds are clean, the energy is weak (values as low as 27). Not much to write home about.

Then, on the 6th of September, we see a new pulse of swell from the NNW, 5ft with an 11-second period. The wind is offshore on the morning, but it’s marked as marginal. The energy is moderate (556). Worth a look if you’re keen, but be aware of the conditions.

The next real standout arrives on the 10th of September. Thursday morning has a 5ft NNW swell, 10-second period, and glassy winds. The afternoon is even better: 5ft NNW swell, a short 7-second period, but dead calm winds. Combined energy is 451 and 321 – both moderate. This is a very promising window, though it’s a week and a half out, so keep an eye on it.

The 11th of September also offers some clean cross-off winds with a 5ft NW swell in the morning and a 4ft NNW swell in the afternoon. Good conditions for a session.

After that, the swell fades again into the 12th.

So, the bottom line: if you want the best surf, hit El Mongol on the morning of Saturday the 29th, Sunday the 30th, or Monday the 31st of August. The 10th of September is also a strong candidate, but it’s a long-range call. The crowds can be a factor here, as it’s often busy, but for those quality windows, it’s worth the company.
