The Lowdown

Alright, Rusty here. Let’s talk about what’s on the menu for the next couple of weeks at El Mongol.

Right off the bat, it’s a quiet start. Nothing much doing for the first week or so. We’re looking at a bit of a flat spell with tiny, wind-affected dribble. The water temp is sitting about average for this time of year, so no surprises there. Don’t get your hopes up for the first few days; it’s a long stretch of “poor surf conditions” all the way through to the end of the week and into the weekend.

Now, there’s a slow build starting on Sunday the 16th. The morning shows a knee-high 4 ft swell out of the north with a short period of 7 seconds, combined energy is moderate at 134. The wind is glassy, so it’ll be clean, but the waves are pretty ordinary. That theme continues into Monday the 17th – similar size, glassy morning, but the waves are just weak and uninspiring. The week after that gets even smaller, with barely a ripple through Wednesday the 19th and Thursday the 20th.

But hold on. Friday the 21st starts to wake up. The morning brings a clean 3 ft swell from the northwest with a period of 10 seconds, and energy climbs to a moderate 174. Glassy wind, so the surface will be smooth, but the waves are still just “ordinary.” It’s a teaser.

The real standout comes on Saturday the 22nd. The morning is dead calm, glassy, with a 4 ft northwest swell at 10 seconds and energy at 264 – moderate but building. That afternoon, though, it kicks off. The swell jumps to a solid 8 ft from the north-northwest, with a period of 12 seconds and combined energy screaming at a massive 1854. That’s strong wave energy. The wind is a gentle cross-shore, so it’ll be a bit lumpy, but the size is real. This is for experts only – that’s well over the 8 ft mark, so keep the beginners out of the water. It’s a big, powerful groundswell, and with that long period, it’ll be lining up nicely on this reef setup.

Sunday the 23rd is another cracker. The morning brings a clean 6 ft swell from the north-northwest at 10 seconds, with light cross-offshore wind and energy at 837. That’s “expect very good surf conditions” territory. The afternoon drops a touch to 6 ft, still clean with cross-offshore wind. Great, solid, rideable waves for experienced surfers. Monday the 24th holds clean smaller options at 4 ft with good winds, still a fun size.

So, the call is simple. Screw the first week. The best on offer is the afternoon of Saturday the 22nd for the big-wave hunters, and then Sunday the 23rd morning is your all-around winner – solid size, clean conditions, and that swell direction of NNW is right in the wheelhouse for El Mongol.

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.
