The Lowdown
Alright, Rusty here, let’s get into it.
First up, the good news. This stretch at El Mongol starts off a bit ordinary, but there’s some proper juice on the way. After Thursday afternoon, which is a bit of a write-off with that cross-on wind and weak energy (92), we start to see Friday morning come alive. Friday the 28th morning is clean—light offshore, 4ft of WNW swell with solid period pushing 11 seconds. The combined energy ramps right up (497), and the water is sitting at 70°, which is a touch warmer than normal for this time of year. That’s a nice little bonus.
Saturday the 29th morning is the standout of the whole run. Glassy conditions, light offshore wind from the SSW, and 5ft of NW swell. Sure, period is a bit short (8 seconds), but the clean surface will make the most of it. The combined energy is moderate (376), and for a spot that’s fairly consistent, this is a proper call. The wind is dead still, so expect clean lines, especially early.
Then Monday the 31st morning is another one to circle. Glassy again, 6ft of NW swell, and period stretching out to 10 seconds. The energy jumps nicely (630), but at nearly 6ft, this might be getting a bit much for beginners. Still, for the more experienced crew, that’s a solid morning. Tuesday the 1st of September also delivers two glassy windows, though the swell drops slightly to 4ft. Good shape, easy paddling.
After that, the swell takes a real dive through the 2nd to the 4th of September. Tiny waves, low energy (down to 30), and while winds are cross-off and clean, there’s just not enough size to get excited about. That’s a three-day flat spell.
But hold on—Saturday the 5th of September brings a new pulse: 5ft from the NNW, period hitting 12 seconds, and combined energy (554) back in the moderate range. Winds are cross-off and clean in the afternoon, so this late-season runner has promise, even if it’s a ways out.
Sunday the 6th morning also looks tidy with glassy conditions and 4ft from the NNW, but by afternoon the cross-on wind messes it up.
From there, it dribbles away into the second week—smaller swells, periods dropping, and energy fading to the low hundreds or less. Nothing really worth setting the alarm for after the 7th.
So the one true standout: Saturday 29th August morning. Glassy, 5ft from the NW, clean as it gets at El Mongol. That’s the session.
The next best: Monday 31st August morning and Friday 28th August morning.
Keep an eye on the 5th of September too—long-range but it has potential.

Information about the El Mongol Surf forecast
The above surf forecast table for El Mongol provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at El Mongol can be found by selecting the local surf guide option on the grey menu. Our El Mongol surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (El Mongol) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for El Mongol may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
El Mongol is 2 km (1 miles) from Gijon. If you plan a holiday in Asturias, look for hotels and other accommodation in Gijon. Gijon has rooms for a wide range of budgets as well as car hire and transport links.
