The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for El Mongol.
Right off the bat, we’ve got a slow start. The first few days are flat and pretty much a write-off. Monday the 24th and Tuesday the 25th are barely showing any life, with tiny, weak swell and poor conditions. You’ll be sitting on the beach watching the tide lines, not surfing. Wednesday the 26th is more of the same – flat, glassy, but nothing to ride. That’s a three-day gap right there with no real surf on offer.
Things start to stir on Thursday the 27th. The swell bumps up to 3ft from the WNW, but the period is a short 8 seconds, so the energy is weak (128). The morning is a bit messy with a cross-off shore, but the afternoon turns glassy. It’s surfable, but nothing to get excited about. Friday the 28th is a bit of a write-off again with a strong onshore wind ripping into a 6ft swell, making it choppy and ugly. The energy is ramping up though (703) – that’s a moderate kick.
Now, Saturday the 29th morning is a real standout for the near term. The wind drops to nothing – glassy – and the swell is a solid 5ft from the NNW with an 8-second period. It’s not a long period groundswell, but the conditions will be clean and the energy is decent (322). This is your best bet for the first week if you want a clean session. The afternoon goes cross-shore, so get out early.
We then hit another gap. Sunday the 30th and Monday the 31st morning see a building swell. Monday the 31st morning is the real gem here: a clean 7ft from the NW with a 10-second period, glassy wind, and the wave energy is pumping (765). That’s a very good looking session. The afternoon gets a bit cross-on, but the morning is a winner. Tuesday the 1st of September keeps the quality up with a 6ft NW swell and glassy conditions in the morning. That’s another top pick for the start of the week.
After that, the swell drops off again through Wednesday the 2nd and Thursday the 3rd. The energy fades, and the conditions become less interesting. Friday the 4th has a pulse of 5ft from the NW with a long 12-second period, but the wind is cross-on, so it’s not clean. The energy is building again though (502).
Now, here’s the big one. Hold onto your board. We’ve got a serious long-range promise for Monday the 7th of September. The morning is looking like a beast: 12ft from the NW with a 17-second period. That’s a very long period groundswell. The wave energy is enormous (6528). The wind is glassy. This is an expert-only session – that size is too big for beginners. The long period means the waves will be lining up with serious power, best handled at a reef break like El Mongol. It’s a standout, but it’s a week away, so keep an eye on the forecast. The afternoon drops to 10ft with a 15-second period, still huge, but with a bit of onshore wind.
Tuesday the 8th of September settles down to 5ft from the NNW, with a 12-second period, but the wind is onshore, so it’s more of a marginal day.
Overall, the best on offer is Monday the 31st of August morning for a safe, clean, fun session, and the absolute standout for the experienced crew is that Monday the 7th of September morning glassy monster. El Mongol is a reasonably consistent reef break, but it can get crowded, so expect some company on the good days.
Rusty.

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.
