The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got El Mongol (El Mongol) on the radar. This spot is a consistent reef break that’s fairly exposed to the swell, and it's going to see a few really good windows over the next couple of weeks. The water temp is sitting at 69°, which is about normal for this time of year, so no surprises there.
The real standout is Wednesday morning, September 9th. That’s the one to circle. We’re looking at a 7ft swell from the NNW with a 10-second period, and the combined energy is a solid 919 – that’s strong, powerful stuff. The wind is glassy, dead calm. That’s a recipe for clean, punchy reef waves. The swell is over 5ft, so it’s getting a bit hefty for the beginners, but for an intermediate crew, that’s a proper session. The direction is a touch off the optimum, but with that energy and glass, you won’t care.
Before that, we’ve got a few smaller, fun days. Tuesday afternoon, September 1st, brings a clean 4ft from the NW with a 9-second period and a moderate 338 energy. The wind is a gentle cross-offshore, so it’ll be clean. Saturday morning, September 5th, has a similar 4ft from the NW, but the period jumps to 11 seconds, giving it a bit more grunt (339 energy) and that nice, lined-up feel. Sunday morning, September 6th, is also looking tidy with a 4ft swell from the NNW and glassy conditions, energy at 490 – that’s a solid morning.
There’s a bit of a lull from the 7th through the 8th, with smaller, weaker swell and less favorable wind, so don’t bother. Then, after the 9th, it drops back down. Thursday morning, September 10th, is worth a paddle with 5ft from the NNW and glassy conditions again (344 energy). Saturday morning, September 12th, has a 5ft from the NW, but it’s a short 8-second period, so it’ll be a bit softer and less defined. The energy is moderate at 299.
Looking further out, Tuesday morning, September 15th, is a promising one. It’s a 4ft NW swell, but the period is back to 9 seconds and the energy is 378. The wind is dead calm, so it’ll be glassy. The afternoon gets a bit bigger at 5ft and longer period (11 seconds), with a big energy jump to 644, but the wind turns cross-onshore, which messes with the surface. Wednesday morning, September 16th, also has a nice 4ft from the NW with a 10-second period, energy at 305, and again, total glass. That’s a clean, easy morning.
Crowds at El Mongol are often, so expect company, especially on those glassy, clean days. But for the quality on offer, it’s worth it.
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.
